Description: | 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)] Specimen has circular mark matching likely location of old-style Leeds number. There is a detached number (a handwritten '122') with the crocodile material, but there is no way of knowing if this is the relevant number (the glue marks have been distorted by the number being reglued to a piece of paper). The old '122' is probably a reference to an old catalogue number, as V1809 appears to be the '122' referred to in the Eyebury Catalogue, and has a printed number '122' on it.
This is an astonishingly large size for a crocodile pubis, given that the partial nature implies a pubis fully twice this length. Given the size, this specimen does seem more likely to be a steneosaur than a metriorhynchid.
The Adams-Tresman formula for species determination cannot be applied, as no cranial features present. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | VERTTETRREPTIL : CROCTELE : FOSSIL : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
