Fissure Deposits of the United Kingdom

During his time at the VMNH, paleontologist Nicholas Fraser collected thousands of microvertebrate samples from Triassic fissure deposits from England and Wales. The samples include isolated bones and teeth of rhynchocephalians, procolophonians, drepanosaurs, indeterminate archosaurs, dinosauromorphs, and crocodylomorphs.
