A Berthasaura leopoldinae 3d Reconstruction by Alex Pritchard Dinosauria - Dinosaur Fossil Replicas

Reconstructed skull of Duriavenator hesperis showing known material (white) of the holotype and only known specimen. Unknown bones based on related Eustreptospondylus oxoniensis. Scale bar is 10cm, image is 10px/cm. Cranial anatomy based on Benson (2008) "A redescription of "Megalosaurus" hesperis (Dinosauria, Theropoda) from the Inferior Oolite (Bajocian, Middle Jurassic) of Dorset, United Kingdom"

Reconstruceted skull of Dubreuillosaurus illustrating known (white) and unknown (grey) material. Scale bar is 10cm. Based of figures and description of Allain (2002) "Discovery of megalosaur (Dinosauria, Theropoda) in the middle Bathonian of Normandy (France) and its implications for the phylogeny of basal Tetanurae"

Illustration of Sinusonasus (Dinosauria, Theropoda, Coelurosauria, Deinonychosauria, Troodontidae). This restoration is an edited and updated version of a drawing I originally uploaded on Wikimedia at December 11th 2009 (which i turn is based on a fossil seen at http://site.sinodino.com/Museum/images/Sinusonasus.JPG.).
