Fusion of sacrals and anatomy inChampsosaurus(Diapsida, Choristodera)
Historical Biology, 2007Sacral centra are occasionally fused with or without severe deformation in Champsosaurus (Diapsida, Choristodera). The sympatrical occurrence of fusion and non-fusion of sacra in adults through their evolution questions that sacral fusion represents the final form of a simple ontogenetic change or specific variation.

A “beaded” sphenodontian (Diapsida: Lepidosauria) from the Early Cretaceous of central Mexico
Journal of Vertebrate Paleontology, 1997ABSTRACT The Albian sphenodontian Pamizinsaurus tlayuaensis, gen. et sp. nov., from the Tlayua Quarry, Central Mexico, is described. The holotype is a posthatchling characterized by the presence of rows of small rounded osteoderms transversally oriented, relatively few hatchling teeth each with well-developed ridges, and a posteriorly displaced ventral

Limb Ontogeny, Evolution and Aquatic Adaptation in the Neodiapsida (Reptilia: Diapsida)
1995This study examines the phylogeny and ontogeny of limb evolution in the Neodiapsida (Reptilia). Patterns and sequences of limb ossification are described from the ontogenies of fossil and extant, aquatic and terrestrial, neodiapsids. Taxa described in detail include the extant squamate Varanus timorensis, the fossil neodiapsids Hovasaurus boulei ...

The first Middle Triassic ichthyopterygian (Reptilia, Diapsida) from Croatia
The Žumberak Mountains are situated in northwestern Croatia, where they represent a part of the Internal Dinarides. A substantial exposure of Triassic sedimentary rock is present in this area, most of which comprises poorly to non-fossiliferous dolostones formed on a carbonate platform.Vidaković, Fran +2 more
