Description: | 10 [feet] depth, Pit number 8, Peterborough [district, Cambridgeshire], [England] [probably ex.] [Bed 10 (Hudson & Martill, 1994)], Oxford Clay [Formation, Peterborough Member, ("Gryphaea and Reptile Beds")], [*Kosmoceras jason jason* Zone],[Middle Callovian], [Jurassic (Middle)] ...nasal (L), pre-frontals (2 frags of each), post-frontal (R posterior 1/2), vomer/parasphenoid (anterior fragment), quadrato-jugals (head and junction with jugal of L, ramus and junction with jugal of R), parietals (central fragment), squamosals (2), sclerotic plate fragments (3); lower skull: articulars (2), angulars (R, with distal half of L), surangular (L, posterior 4/5), coronoid (head of R), splenials (2 - anteriorly fused), dentaries (2, some damage to R tip), teeth (6/3); loose teeth (22); shoulder girdle: coracoid (R), humeri (L + distal 1/3 of R), pelvic girdle: pubes (2, L + distal frag of R), ilia (2), ischia (2 - R more damaged, but anterior processes missing from both), femora (2), 2 epipodial fragments; vertebrae: anterior wedge bone, atlas/axis, cervical (5), dorsal (18), sacral (2), caudal (12 anterior, 5 middle, 1 posterior); ribs: middle cervical (2R, 1L), anterior dorsal (3), middle dorsal (21 - 6 virtually complete), rib shaft fragments (41), transverse process fragments (5), zygapophyseal fragments (8), neural arch fragments (5), neural spine fragments (7), chevron (1 L fragment + 1 posterior chevron fragment); miscellaneous fragments (87).
Number of fragments reduced from 469 to 346. Evidence for age of specimen comes from the non-fusion of splenials to dentaries, and the non-fusion of articular/angular/surangular.
The Adams-Tresman formula for species determination (width of post-frontals to length of skull) could not be applied, owing to the fragmentary nature of the remains.
