Crocodylomorph and early archosaur collections
The Museum's crocodylomorph and early archosaur collections include an estimated 5,000 specimens, from isolated incomplete bones to articulated skeletons on slabs and mounts.
Although many specimens are from pyrite-bearing strata vulnerable to decay, our crocodylomorph collection is generally in very good condition.
At least a fifth of the collection space is occupied by Triassic archosaurs from the UK and abroad, including Ornithosuchus, Scleromochlus, Erythrosuchus, aetosaurs and phytosaurs.
British Mesozoic crocodylomorphs are very well represented due to a long history of collecting across the British Isles in the Lower Lias Group, Upper Lias Group, Kimmeridge Clay Formation, Oxford Clay Formation and Purbeck Beds. Specimens include:
The collections include a large number of foreign specimens from parts of Europe, the Indian subcontinent and Africa.
The fossil crocodylomorphs are used in a wide range of research projects, ranging from taxonomic revisions to biomechanical and palaeoecological studies.
