Atreipus

Fossil samples – e.g. ‘primitive’ bony fish (1, 2), a skull of a temnospondyl ‘amphibian’ (probably a metoposauroid) in dorsal view (3), a skull of an archosaur of the crocodile lineage (probably a phytosaur) in palatal view (4), holotype of the “gliding reptile” Icarosaurus siefkeri [1] (5) and Atreipus-Grallator-type dinosaur tracks (bottom right) – from the Newark Supergroup, i.e. a series of mainly Late Triassic to Early Jurassic sedimentary rocks of eastern North America ↑ Edwin H. Colbert: A gliding reptile from the Triassic of New Jersey. American Museum Novitates, 2230. American Museum of Natural History, New York 1966, digitallibrary.amnh.org, cf. fig. 3 therein.

Lower Triassic fossil footprint (ichnite) of the ichnogenus Chirotherium, probably caused by an early archosaur, and first discovered 1833 in Hildburghausen (Thuringia, Germany). This specimen, however, ist from the Helsby Sandstone of the Storeton Quarry near Liverpool. Its species name is Chirotherium storetonense.[1]
