The Triassic reptiles from Devon

Fossil reptiles have been known from the Otter Sandstone Formation in south-east Devon since the 1860s. Early finds were limited, but riley indicated relationships with Middle Triassic reptile faunas already known from the Midlands of England. Almost no work was done on the Devon Triassic reptiles until the 1980s, when extensive new collections were made. The fauna of fishes, amphibians, and reptiles includes about ten taxa, and these suggest an Anisian (early Mid Triassic) age for the Otter-Sandstone Formation. The fauna fills an important gap between terrestrial tetrapod faunas of the same age in Russia and North America, and shows an unusual mix of Laurasian and Gondwanan elements.
