Clay figurines from the Middle to Late Preclassic San Isidro Site of western El Salvador.

Bolinas-type figurines are clay figurines from the Middle Preclassic (1000-350 BC) and Late Preclassic (350 BC-250 AD) periods of Mesoamerica, known from a number of sites along the Pacific coasts of Guatemala and El Salvador. They get their name from the Finca Bolinas Ranch in El Salvador, where the first examples were discovered in the mid-twentieth century. A total of 95 figurines were unearthed at Finca Bolinas, although not by an organised archaeological excavation, so much of the context in which they were originally buried has been lost. 

Of these 95 figurines, 93 were female and only two were potentially male. They were depicted either standing or sitting with their legs parted. The largest figurines were over 20 cm tall. The figurines were made from a cream or reddish-brown material, were evenly fired, and then smoothed or polished. Most of the figurines from Finca Bolinas have traces of either white or orange slips (some have both), and a few have traces of black paint. Most wear some kind of jewellery, such as anklets, bracelets, necklaces, or earspools, and most have hair styles, including simple buns, curls, braids, and more elaborate coiffures. Some of the figurines which lack earspools have holes in their earlobes, which have been interpreted as possible attachments for earspools made from a different material, such as jade. Many of the figurines are naked, others have coverings on their lower bodies, leaving their chests exposed, although breasts are either very small or absent completely. Most figurines are cast  in a single piece, but some have protrusions and sockets which enable articulated heads or limbs to be attached.

Bolinas-type figurines were also found at the monumental Kaminaljuyu site in Guatemala City, which was excavated in the 1940s and 1950s by the Carnegie Institution, and later excavations at Vista Hermosa in Guatemala, and Santa Leticia, and Ataco  Zapotitán Valley in El Salvador, though all of these figurines were fragmentary in nature, leading the archaeologists studying them to conclude that these were mundane domestic objects, possibly toys for children, which were deposited on household middens at the end of their usefulness, and then sometimes recycled into core-fill for monumental structures. 

In 2012 an excavation at Tak’alik Ab’aj on the Pacific-facing piedmont of the western Guatemalan highlands uncovered a burial with lavish funerary offerings comprised several high-quality ceramic vessels, jade jewellery, including a four-string necklace with a celtiform pendant in the form of an avian personage, and, in one corner, six broken but complete Bolinas figurines. This burial was dated to the Nil 2 ceramic phase of the late Middle Preclassic Period, or between 350 and 100 BC. 

The Bolinas figurines from Tak’alik Ab’aj were placed overlapping one-another, arranged along a north-south axis. All were standing naked females, placed with their arms band and their hands on their stomachs, their eyes open, and their lips parted to reveal their teeth. The smallest figurine was 273 mm tall, the largest 424 mm. One had an articulated head, which could be turned to face to the sides, two had apparently been painted with elaborate black markings. All were capable of standing, despite having distinctively small feet.

In a paper published in the journal Antiquity on 5 March 2025, Jan Szymański and Gabriela Prejs of the Faculty of Archaeology at the University of Warsaw, describe a set of five Bolinas figurines from the top of a large monumental structure at San Isidro, a large Middle to Late Preclassic site in the Department of Sonsonate, western El Salvador, during field work in 2022.

The layer from which the figurines was recovered has been dated by ceramic typology and radiocarbon assays to between 410 and 380 BC, slightly older than the Tak’alik Ab’aj site. The five figurines were found at the southern end of the excavated area. Three of the figurines are approximately 30 cm high, and made of a fine, cream-coloured material, while the remaining two are smaller, at 18 and 10 cm, and made of a courser, orange-brown paste. All had apparently been covered by a white slip, which can be seen best on the legs and lips, patches of red slip can be seen on the backs of the figurines. The three large figurines have articulated heads, with a protruding neck which fits into a socket on the base of the head. Each of the heads has a pair of holes drilled into the top, while the necks have a horizontal hole and a vertical groove on each side, which would have allowed a string to be passed through, holding the head in place; this is identical to the means of articulation seen at Tak’alik Ab’aj.

The three larger figurines lack any hair or jewellery, while the two smaller figurines have locks on their foreheads and earspools; the smallest figurine also has bracelets and what appears to be a necklace on the chest.  This smallest figurine has its hands beneath its chin, while those of all the others lie on their abdomens. Both small figurines and two of the females are interpreted as female, while one of the larger figurines is interpreted as male, on the basis of its more elongated torso and shorter, thinner hips, and an incised linear pattern on the face, which appears to represent tattoos or scarification. If identified ccorrectly, this is the most complete male Bolinas figurine discovered to date.

All of the figurines were discovered within an area of 0.6 m², at a depth of less than 50 cm below the surface. The figurines were all orientated 15° north of east-west, except the smallst, which was orientated 15°east of north-south. The larger figurines are also orientated with their feet along a line 15°east of north-south, parallel to the axis of the smallest figurine. The northernmost figurine is one of the large females, face down, with her head to the west. South of this, the second large female figurine lies face up with her head to the east. Next the smallest figurine lies face down with her head to the north (and the second female figurine), then the larger of the two small figurines, face up and head to the east, parallel to the two large figurines in this orientation, but without her feet on the same line. Finally, the large male figurine lies on his back with his feet to the west and head to the east, parallel to the other figurines in this position, with his feet on the line as the two large female figurines.

The figurines appear to have been deliberately placed in a planned out way, however, Szymański and Prejs note that the site was excavated on freely-accessible agricultural land (i.e. not a secure site) over a period of several days. Furthermore, the spot where the figurines were found was covered by a Bullhorn Tree, Acacia cornigera, with roots passing through the figurine-containing area, which may have moved their position over time.

The larger dolls, with their movable heads, invite comparison to modern dolls. However, clay is a poor material choice for toys, and the long limbs of the figurines would seem likely to break quickly in any form of play, leading Szymański and Prejs to conclude that the purpose of the figurines is more likely to have been artistic or ritual. They build upon this to suggest that the movable heads imply that they may have been used as marionettes or puppets, either to act out some ritual performance, or arranged in some form of tableaux.

The Bolinas-type figurines from Tak’alik Ab’aj were also apparently arranged in a form of tableaux, with figurines placed in pairs on the cardinal directions along a scaled-down horizon circle. This led archaeologist Christa Schieber de Lavarreda to propose that the figurines were used in an elaborate ritual at the end of funerary rights, in the form of a dance representing the movements of the Sun and the cycle of life.

Tak’alik Ab’aj National Archaeological Park. Schieber de Lavarreda (2016).

The figurines from San Isidro resemble those from Tak’alik Ab’aj in that they will stand upright unaided, which raises the possibility that these figurines were also used to act out some sort of scene before burial. The figurines are broken in a number of places which do nor appear to be obvious week points, which may indicate that they were deliberately broken before being buried, although Szymański and Prejs observe that they are likely to have been made in more than one piece and then assembled, which would have created week points in less obvious places.

The arrangement of the figurines at San Isidro is clearly non-random, and therefore presumably had some significance to the people who deposited them. Notably, all of the figurines, if returned to an upright position would have faced to the west, except for the smallest, which may have faced north, or may have been disturbed by the growth of the tree roots. The west, in Mesoamerican cosmography, is generally considered to be the realm of death (although this understanding is largely derived from Mayan culture). This may indicate that the placement of the San Isidro figurines was part of a funerary right, despite the absence of any Human remains at the site. 

San Isidro is a complex of structures; figurines were recovered from the top of a mound designated Cerrito 1, which lies on the eastern side of a plaza. On the western side of this plaza lies a smaller structure, designated Trapiche 3, from which a large, unmarked, stela (slab) was recovered in 2018. Facing in a 15°-north-of-west direction, the San Isidro figurines would have looked directly at the Trapiche 3 mound and its stela.

The three large figurines from San Isidro are naked, which is not unusual in Bolinas figurines, lack any jewellery, although the large holes in the ears may have served as attachments for earspools, and all lack hair, which is more unusual. It is possible that all these features were made of perishable material and have perished since their burial.

All the San Isidro figurines have their mouths open, which may imply that they were intended to be depicting people engaged in speech or song. The smallest figurine also has its hands raised to its chin, which is harder to interpret. Hands covering the mouth might indicate the keeping of secrets, but this is not the case. Possibly the figurine was originally intended to be holding a whistle or ocarina, or possibly just a food item. White kaolin has been found in the mouths of all five figurines, which might relate to some form of feeding ritual.

The heads of the larger figurines appear to have been adjustable rather than truly movable, and it is unclear how this would have been used. Possibly the heads were placed in different positions at different points in the ritual. Alternatively, the figurines may have had a longer life cycle, being used in multiple rituals before their eventual burial, leading to a need for adjustable, or even replaceable, heads for different rituals.

The San Isidro figurines are only the second Bolinas figurines discovered in situ, which limits the amount which should be inferred from them. What can be stated with some confidence is that their placement is non-random, although the purpose of the way in which they are arranged is far from certain. The presence of figurines in a prone (face down) position is curious. If these figurines were intentionally placed in this position, then was there some significance to it. Burial of Humans in a prone position is also known from Mesoamerica, including Preclassical El Salvador, although this is rare, and the reason behind it is unknown.

It is also unclear whether the figurines represent actual people. It is possible that the male figurine represents a ruler or other important figure, and that the two large female figurines represent wives (one of whom might have pre-deceased him, indicated by having her figurine placed face down) and the two smaller figurines daughters, again, with one placed face down, potentially representing having predeceased her father. Alternatively, the figurines might represent household deities similar to the Roman lares and penates, or possibly anthromorphised depictions of cultural concepts, such as the statues of justice seen on court houses in many parts of the world today. Another possibility is that they are intended to be ritual servants for the afterlife, similar to the ushabti figurines placed in tombs by the Ancient Egyptians. Szymański and Prejs suggest that the markings on the face of the male figurine may indicate that he represents an actual person, while they are less certain about the more generic female figurines.

As well as the figurines, there are other items which were found at both Tak’alik Ab’aj and San Isidro, such as miniature jade celtiform pendants representing avian personages, and tubular and disk beads made using similar techniques. Nevertheless, the Tak’alik Ab’aj site was clearly a burial, while no evidence of Human remains, or even a place where they might once have been placed, has been found at San Isidro. At both sites, the figurines were clearly laid out in a specific arrangement, but the arrangements were different, possibly providing further evidence that the purpose of the two sites was different.

Szymański and Prejs believe that ritualised puppet-theatre was practiced in late Middle Preclassic and early Late Preclassic periods in south-eastern Mesoamerica. They suggest that at least some of the figurines were interchangeable in purpose, generic enough that different costumes and heai pieces would have allowed them to undertake different roles in different performances, while other figurines may have been more specific in their purpose.

Magnitude 6.2 Eaarthquake off the coast of Guanacaste Province, Costa Rica.

The United States Geological Survey recorded a Magnitude 6.2 Earthquake at a depth of 16.0 km, off the west ciast of Costa Rica, roughly 41 km to the west of the town of Tamarindo in Guanacaste Province, Costa Rica, slightly before 11.45 am local time (slightly before 5.45 pm GMT) on Saturday 12 October 2024. There are no reports of any damage or casualties associated with this event, but it was felt across much of northern Costa Rica and southern Nicaragua.

Costa Rica lies on the southern margin of the Caribbean Plate; to the south of the country the Cocos Plate, which underlies part of the eastern Pacific Ocean) is being subducted under the Middle American Trench, passing under Central America as it sinks into the Earth's interior. This is not a smooth process, and the plates often stick together until the pressure builds up enough to force them to shift suddenly, causing Earthquakes. As the Cocos Plate sinks deeper if is partially melted by the friction and the heat of the Earth's interior. Some of the melted material then rises up through the overlying Caribbean Plate, fuelling the volcanoes of Central America.

Magnitude 6.4 Earthquake off the coast of the Mexico/Guatemala border.

The United States Geological Survey recorded a Magnitude 6.4 Earthquake at a depth of 75.4 km, approximately 17 km off the south coast of the border between Mexico and Guatemala, slightly before 5.40 am local time (slightly before 11.40 am GMT) on Sunday 12 May 2024. This even was felt across much of southern Guatemala, and Chiapas State, Mexico, and triggered a number of small landslides as well as minor damage to some buildings, but there are no reports of any injuries.

Mexico is located on the southernmost part of the North American Plate. To the south, along the Middle American Trench, which lies off the southern coast off Mexico, the Cocos Plate is being subducted under the North American Plate, passing under southern Mexico as it sinks into the Earth. Guatemala is located on the southern part of the Caribbean Plate, close to its boundary with the Cocos Plate, which underlies part of the east Pacific. The Cocos Plate is being pushed northwards by expansion of the crust along the East Pacific Rise, and is subducted beneath the Caribbean Plate along the Middle American Trench. This is not a smooth process, and the plates frequently stick together then break apart as the pressure builds up, causing Earthquakes on the process.

The Cocos Plate is thought to have formed about 23 million years ago, when the Farallon Plate, an ancient tectonic plate underlying the East Pacific, split in two, forming the Cocos Plate to the north and the Nazca Plate to the south. Then, roughly 10 million years ago, the northwesternmost part of the Cocos Plate split of to form the Rivera Plate, south of Beja California.

In a paper published in the Journal of Geophysical Research, in 2012, a team led by Igor Stubailo of the Department of Earth and Space Sciences at the University of California Los Angeles, published a model of the subduction zone beneath Mexico using data from seismic monitoring stations belonging to the Mesoamerican Seismic Experiment, the Network of Autonomously Recording Seismographs, the USArray, Mapping the Rivera Subduction Zone and the Mexican Servicio Sismologico Nacional.

The seismic monitoring stations were able to monitor not just Earthquakes in Mexico, but also Earthquakes in other parts of the world, monitoring the rate at which compression waves from these quakes moved through the rocks beneath Mexico, and how the structure of the rocks altered the movement of these waves.

Based upon the results from these monitoring stations, Stubailo et al. came to the conclusion that the Cocos Plate was split into two beneath Mexico, and that the two plates are subducting at different angles, one steep and one shallow. Since the rate at which a plate melts reflects its depth within the Earth, the steeper angled plate melts much closer to the subduction zone than the shallower angled plate, splitting the Trans-Mexican Volcanic Belt into sections above the different segments of the Cocos Plate, and causing it to apparently curve away from the subduction zone.

Top the model of the Cocos Plate beneath Mexico, split into two sections (A & B) subducting at differing angles. (C) Represents the Rivera Plate, subducting at a steeper angle than either section of the Cocos Plate. The Split between the two has been named the Orozco Fracture Zone (OFZ) which is shown extended across the Cocos Plate; in theory this might in future split the Cocos Plate into two segments (though not on any human timescale). Bottom Left, the position of the segments on a map of Mexico.

Archaeologists uncover tomb of a Gran Coclé lord in southern Panama.

Archaeologists from the El Caño Foundation have uncovered a tomb which they interpret as belonging to a lord or other important figure from the Gran Coclé culture within the El Caño Archaeological Park in Coclé Province, southern Panama, according to a press release issued by the Panamanian Ministry of Culture. The tomb is thought to date to between 750 AD and 800 AD, and contains a variety of gold and ceramic objects, as well as an elaborate funerary trousseau (burial costume) comprising five pectorals (large medallions work on a necklace in the centre of the breast), two belts of spherical gold beads, four bracelets, two earrings in the shape of human figures (a man and a woman), an earring in the shape of a double crocodile, a necklace of small circular beads, five earrings made with sperm whale teeth with gold covers, a set of circular gold plates, two bells, bracelets and skirts made with dog teeth and a set of bone flutes.

Most notably, and in common with other burials associated with important people of the Gran Coclé culture, the main occupant of the tomb was not buried alone, but with a number of companions. Previous excavations of such tombs have found between eight and thirty two people buried in addition to the main occupant, who were presumably either sacrificed at the time of the tomb owner's death, or had died previously and been stored elsewhere until the main burial. The tomb has not yet been completely excavated, so it is unclear how many additional bodies there are. What is noteworthy is that the  main  occupant of the tomb was buried face down (common for important Gran Coclé figures) on top of the body of a woman.

The El Caño Archaeological Park contains a series of funerary sites associated with the Gran Coclé culture, dated to between 700 AD and 1000 AD. The site has been excavated intermittently since it was discovered in 1925, and is considered to be Panama's most important archaeological site as well as a major tourist attraction, making an important contribution to the economy of the region.

Jade mask among items found in Mayan tomb in Guatemala.

A mosaic jade mask is among the items discovered in a 1700-year-old Mayan tomb in Guatemala, according to a press release issued by Tulane University on 29 January 2024. The site, at Chochkitam, close to the borders with Mexico and Belize, was investigated by a team led by archaeologist Fran Blom of the Middle American Research Institute at Tulane University in 1924, but nothing was discovered at that time. In 2022 a series of tunnels was detected in a lidar (Light Detection and Ranging, a system of scanning land surface and near-surface structures from an aircraft using lasers) survey of the area, leading to an investigation on the ground led by Francisco Estrada-Belli of Tulane University.

The tunnels discovered by the lidar survey turned out not to be connected to the tomb, or any other structure, and are thought to have been dug by would-be-looters with some idea that there was a tomb in the area, who eventually gave up before finding it. The actual tomb was located about 2 m from the end of the looters tunnel. This was found to be remarkably intact, although part of the stone ceiling had collapsed, and some natural decay had set in.

The tomb contains a series of Human femur bones inscribed in a Mayan hieroglyphic script, which identify the occupant of the tomb as a previously unknown Mayan king, listing his father and grandfather, which makes it possible to link him to the Maya states of Tikal in Guatemala and Teotihuacan, to the northeast of Mexico City . The tomb is thought to have been sealed in about 350 AD, and also contains a series of shells of the Mollusc Spondylus, a type of Spiny Oyster, which were used as currency by the Mayans.
