Abstract

Abstract: Triassic sediments recovered from fissure and cavity systems in Carboniferous Limestone at Cromhall Quarry, Gloucestershire, England have been found to contain abundant reptilian remains. Owing to the lack of spores, the precise ages of the fills are difficult to determined but evidence presented suggests they are Late Norian. Over ten genera of archosaur and lepidosaur have been identified from seven different fissure fills and the different faunal assemblages may represent successional ecosystems. The reptiles are mostly small and the largest, a dinosaur, is no more than one metre long. The lepidosaurs include five or six sphenodontids and the dentitions of four of these are examined in detail. The dietary habits of the sphenodontids are assessed, and by comparison with modern lizards it is concluded that at least one species was herbivorous. Different degrees of tooth wear in some species indicate that there was some intraspecific variation in diet. Interspecific competition partly explains the occurrence of the different proportions of each reptile observed at each of the seven sites.
