Stegouros elengassen holotype and skeletal

Holotype skeleton (AGB 6257) of Cartorhynchus lenticarpus on display at the Geological Museum of China.

The holotype anterior dorsal vertebra of Uragasaurus kalasinensis (PRC 460) in anterior (a) and posterior (b) views. Digital rendering of the specimen in anterior (c), posterior (d), right lateral (e), left lateral (f), dorsal (g), and ventral (h) views. Asterisk refers to an autapomorphic character. The blue highlight indicates the pneumatic fossa and pleurocoel.

A cast of BYU 9025, the holotype fossil of the sauropod dinosaur Supersaurus, a giant scapulocoracoid measuring 2.4m long. • The source photo was taken at the Dinosaur Journey Musuem. • Notes regarding the file; This image was edited and extracted from the original seen here. [1] The Photoshop CC lens correction profile and a 'perspective warp' correction were applied.

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.

Quarry map showing the spatial distribution of the holotype of Uragasaurus kalasinensis and associated materials from the Phu Noi Locality (g). PRC 460 (Uragasaurus kalasinensis holotype) is indicated in red. Associated sauropod elements include KS 34-586, KS 34-587, KS 34-588, and KS 34-602a–b, highlighted in yellow, green, blue, purple, and pink, respectively. The inset shows a close-up of the excavation grid highlighting the relative positions of the holotype and nearby associated materials. Each grid square represents 0.75 × 0.75 m.
