Wahlisaurus massarae: A new species of Ichthyosaur from the Early Jurassic of Nottinghamshire, England.

England is noted for having produced a large range of Early Jurassic Ichthyosaur specimens, though the majority of these have come from the Jurassic Coast area of Dorset, with specimend also described from Somerset, Leicestershire and Warwickshire. A number of specimens are also known from the Early Jurassic of Nottinghamshire, though to date these have been the subject of little organized study.

In a paper published in the Journal of Systematic Palaeontology on 13 June 2016, Dean Lomax of the School of Earth, Atmospheric and Environmental Sciences at The University of Manchester describes a new species of Ichthyosaur from the Early Jurassic Scunthorpe Mudstone Formation of the Normanton Hills, near Normanton on Soar in the district of Rushcliffe, Nottinghamshire.

The species is described from a single specimen, obtained from the collection of Percy Faulks by the Leicester Arts and Museums Service. The specimen has been prepared mechanically and by acid disolution some time between 1952 and 1981, and is currently in several pieces, with the majority on three large blocks. It is named Wahlisaurus massarae, in honour of William Wahl and Judy Massare for their contributions to the study of Mesozoic Marine Reptiles.

Basioccipital, rostrum and dentition of Wahlisaurus massarae. (A) Basioccipital in posterior view; note the extensive extracondylar area, fragment of the left stapes and portion of basisphenoid. (B) Ventral view of mandible and snout with anterior portion of dentary rotated (in dorsal view) and positioned adjacent (dashed line indicates point of fit); note the slenderness of the rostrum and the presence of an overbite. (C) Close-up of the large, long and robust teeth and some of the needle-like teeth positioned under the maxilla. (D) Close-up of three dentary teeth; note the ‘waisted’ morphology, recurved crown and infolded root. Abbreviations: bas, basisphenoid; den, dentary; mx, maxilla (right maxilla); pmx, premaxilla; sta, stapes. Scale bars: (A) 5 cm; (B) 10 cm; (C) 3 cm. Lomax (2016).

The specimen has variable preservation, with some portions articulated and well preserved, and others completely disarticulated and worn The skull is partially crushed with some portions missing completely. It is thought to be a sub-adult, with only partial fusion of the skull and patches of roughness on the articulating surfaces of the humerus, which would be expected to be smooth in a fully mature specimen.

    Hello everyone in this forum, I am Jane Robin from palm Harbor Florida 34682. USA and want to use this medium to express gratitude to UP START LOAN for fulfilling their promise by granting me a loan, i was stuck in a financial situation and needed to refinance and pay my bills as well as start up a Business. I tried seeking for loans from various loan firms both private and corporate organisations but never with success, and most banks declined my credit request. But as God would have it, i was introduced by a friend named Mary Williams to UP START LOAN whom also confirmed to me that she also obtained a loan from them. In an attempt to resolve my current situation, i got in contact with the company via email and undergone the due process of obtaining a loan from the company, to my greatest surprise within 48hrs just like my friend Mary, i was also granted a loan of $80,000.00; So my advise to everyone who or know someone who desires a loan, if you must contact any firm with reference to securing a loan online with low interest rate of 2% and better repayment plans/schedule, please contact UP START LOAN. Besides, he doesn’t know that am doing this but due to the joy in me, i'm so happy and wish to let people know more about this great company whom truly give out loans, it is my prayer that GOD should bless them more as they put smiles on peoples faces.
