Phylogeny of Drepanosauridae (Reptilia: Diapsida)
Journal of Systematic Palaeontology, 2004Synopsis Phylogenetic analysis reveals that the Triassic diapsid family Drepanosauridae is closely related to Coelurosauravus and Longisquama. These three taxa are part of a clade for which the name Avicephala (defined as all taxa more closely related to Coelurosauravus and Megalancosaurus than to Neodiapsida) is coined. Avicephala is a sister taxon to

New material of the enigmatic reptile Khurendukhosaurus (Diapsida: Choristodera) from Mongolia
Die Naturwissenschaften, 2008New material of the enigmatic diapsid Khurendukhosaurus is described from the Mongolian type locality, Khuren Dukh, providing additional data on the vertebral column, pelvis, and hind limb. It confirms the choristoderan status of the genus and permits a more detailed phylogenetic analysis that supports a relationship between Khurendukhosaurus and the ...

Postcranial paleoneurology of the Diapsida
Journal of Zoology, 1995 The relationships between the size of the spinal cord and the size of the neural canal, and between gross spinal cord anatomy and locomotor style, were documented in a wide range of living diapsids. Observed relationships were used to make predictions about spinal cord anatomy and about limb use and position in related fossil taxa.

Sexual dimorphism in Champsosaurus (Diapsida, Choristodera)
Lethaia, 2004 Two nearly complete specimens of Champsosaurus (Diapsida, Choristodera) with distinctive morphologies, from the Tullock Formation (Early Paleocene) of northeastern Montana, USA, were described as different species. The limb bones of C. ambulator are more robust than those of C. laramiensis, indicating that C. ambulator was more adapted for walking than

Zoological Journal of the Linnean Society, 1987
The holotype of the Upper Permian gliding reptile Weigeltisaurus jaekeli is redescribed. Comparison with the Madagascan reptile Coelurosauravus shows that the two forms are congeneric. Coelurosauravus Piveteau, 1926 has priority. The Upper Permian genus Gracilisaurus Weigelt, 1930 is reviewed and referred to Coelurosauravus.
