The early composition and evolution of the turtle shell (Reptilia, Testudinata)

Palaeontology, 2018
The shell of the oldest true turtle (Testudinata) branch (Proterochersidae) from the Late Triassic (Norian) of Poland and Germany was built in its anterior and posterior part from an osteodermal mosaic which developed several million years after the ...

Revision of the Triassic European turtles Proterochersis and Murrhardtia (Reptilia, Testudinata, Proterochersidae), with the description of new taxa from Poland and Germany

, 2016
A recently discovered Norian outcrop in Poreba, Poland, has yielded numerous well-preserved turtle remains. These, together with historical materials from Germany, enabled the identification of two new proterochersid taxa: Proterochersis porebensis sp ...

Reptilia-Related Viruses

1978
Publisher Summary Reports concerned with reptilia-associated viruses are few in number compared to those on viruses of the other four major vertebrate classes. The amphibia have generated numerous virus-related publications, restricted in general to frog viruses involved in the initiation of Lucke renal adenocarcinoma and the polyhedral cytoplasmic ...

Serological Studies of the Reptilia

The Journal of Immunology, 1939
Summary This study of the hemagglutinogens and the hemagglutinins of turtle-blood included the possibility of blood-grouping within this group of animals, and the relationship of the hemagglutinins and hemagglutinogens of turtle and human blood.

The ultrastructure of the vomero-nasal organ in reptilia

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1970
There are three types of cells in the vomero-nasal organ of Lacerta sicula and Natrix natrix: receptor cells, supporting cells and basal cells. The receptor cells bear microvilli and no cilia. In Lacerta centrioles are lacking, indicating that the ciliary apparatus can have no essential significance in the transducer process. In Natrix centrioles occur

The high-level classification of skinks (Reptilia, Squamata, Scincomorpha).

Zootaxa, 2014
Skinks are usually grouped in a single family, Scincidae (1,579 species) representing one-quarter of all lizard species. Other large lizard families, such as Gekkonidae (s.l.) and Iguanidae (s.l.), have been partitioned into multiple families in recent ...

Phylogeny of the Erythrosuchidae (Reptilia: Archosauriformes)

Journal of Vertebrate Paleontology, 1992
ABSTRACT The Erythrosuchidae are a late Early to early Middle Triassic lineage that represent the first radiation of large terrestrial carnivores within the Archosauriformes. Erythrosuchid monophyly can be established by their possession of a suite of seven shared derived characters. At least five valid genera of erythrosuchids can be recognized.

RES Structure and Function of the Reptilia

1982
A phylogenetic approach to understanding the development and mechanisms of immunity has gained attention only in recent years. On the evolutionary scale, reptiles are pivotal since they are the progenitors of both avian and mammalian classes. It is now agreed that the basic pattern of adaptive immune responsivity was established when the first ...
