The Coccidia (Apicomplexa) of the Archosauria (Crocodylia: Eusuchia) of the World
Journal of Parasitology, 2020The order Crocodylia (suborder Eusuchia) includes 27 species of alligators, caimans, crocodiles, and gharials that are cosmopolitan in distribution, inhabiting subtropical and tropical locations. Numerous surveys (many of them trivial, with small sample sizes) have reported a wide variety of blood and intestinal apicomplexans from 17/27 (63 ...

Phylogenetic relationships of the Atoposauridae (archosauria, crocodylomorpha)
Historical Biology, 1988A systematic revision of the family Atoposauridae is presented, interpreting and reviewing their relationships. The seventy‐one characters have been divided into cranial, postcranial and metric which have been used in three separate cladistic analyses in order to discuss their concordance.

The Skull and Head Muscles of Archosauria
Fascinating Life Sciences, 2019Archosaurs is the clade composed by birds (Aves) and crocodiles, alligators, and the gharial (Crocodylia). This relatedness is not obvious and for a long time was not taken into account, as birds were seen as a group separate even from the rest of reptiles.

Haemothermia or Archosauria? The interrelationships of mammals, birds and crocodiles
Zoological Journal of the Linnean Society, 1988The recently proposed hypothesis that the living birds and the living mammals are sister groups, together forming a natural taxon Haemothermia, is contrasted with the more traditional view, that birds and crocodiles are living sister groups within the taxon Archosauria.

Pachycephalosaur paleoneurology (Archosauria: Ornithischia)
Journal of Vertebrate Paleontology, 1989ABSTRACT Pachycephalosaur endocranial casts display a distinctive suite of traits that include large divergent olfactory bulbs, large olfactory nerves, short thick olfactory tracts, a moderately expanded cerebrum not separated from optic lobes and cerebellum dorsally, steep cranial flexure, and reduced pontine flexure.

Sarmatosuchusand the early history of the Archosauria
Journal of Vertebrate Paleontology, 1997ABSTRACT A detailed description of the early archosaur Sarmatosuchus otschevi Sennikov, 1994, from the Middle Triassic Donguz Formation of southern European Russia, is presented. New morphological data forms the basis of a preliminary investigation of the phylogenetic relationships between a selection of the earliest archosaurs.

On the cervical vertebrae of the Pterodactyloidea (Reptilia: Archosauria)
Zoological Journal of the Linnean Society, 1986Within the Pterodactyloidea, the cervical vertebrae show considerable variation. These elements are also sufficiently common and contain enough anatomical information to make them taxonomically valuable. A survey of these vertebrae concludes that most known pterodactyloids fall into two groups: long-necked forms with attenuated cervical vertebrae that ...

Enamel microstructure of ceratopsian teeth (Reptilia, Archosauria)
Geobios, 1988Abstract The microstructural study of the enamel of ceratopstiandinosaur teeth indicates the presence of two layers, an external non-prismatic layer and an internal prismatic one. Therefore, the prismatic structure among Dinosaurs and other reptiles cannot be related to the feeding habits.

The braincase of Prestosuchus chiniquensis (Archosauria: Suchia)
Geological Society, London, Special Publications, 2013Abstract The osteology of an almost complete braincase of the rauisuchian archosaur Prestosuchus chiniquensis from the Middle Triassic of Brazil is described for first time, based on two specimens (UFRGS-PV-0629-T and UFRGS-PV-0156-T) .
