The Treatise on Invertebrate Paleontology published by the Geological Society of America and the University of Kansas Press, is a definitive multi-authored work of some 50 volumes, written by more than 300 paleontologists, and covering every phylum, class, order, family, and genus of fossil and extant invertebrate animals. The prehistoric invertebrates are described as to their taxonomy, morphology, paleoecology, stratigraphic and paleogeographic range. However, taxa with no fossil record whatsoever have just a very brief listing.
The Journal of Vertebrate Paleontology is a bimonthly peer-reviewed scientific journal that was established in 1980 by Jiri Zidek. It covers all aspects of vertebrate paleontology, including vertebrate origins, evolution, functional morphology, taxonomy, biostratigraphy, paleoecology, paleobiogeography, and paleoanthropology. The journal is published by Taylor & Francis on behalf of the Society of Vertebrate Paleontology. According to Journal Citation Reports, the journal has a 2017 impact factor of 2.190.

Cernay-lès-Reims is a commune in the Marne department in north-eastern France.
Watsonisuchus is an extinct genus of temnospondyl amphibian from the Early Triassic of Australia, Madagascar, and South Africa. It was up to 122 cm long and had a robust skull of 24 cm in length.
Capetus is an extinct genus of temnospondyl from the Upper Carboniferous of the Czech Republic. It reached a length of 150 cm.
Trematolestes is an extinct genus of temnospondyl amphibian from the Lower Keuper of southern Germany. It was first named by Rainer R. Schoch in 2006 and the type species is Trematolestes hagdorni. It is the first trematosaurid represented by a nearly complete skeleton.
Cosmochelys is an extinct genus of sea turtle from the Eocene of Africa. It was first named by Andrews in 1920, and contains one species, C. dolloi.
Protosphargis is an extinct genus of sea turtle from the Upper Cretaceous of Italy. It was first named by Capellini in 1884.
Derwentia is an extinct genus of trematosaurian temnospondyl within the family Rhytidosteidae. It is known from a single skull found from the Knocklofty Sandstone of Tasmania, which is Early Triassic in age.
Jammerbergia is an extinct genus of mastodonsauroid temnospondyl within the family Mastodonsauridae. The only species is Jammerbergia formops, named in 2003 from the Cynognathus Assemblage Zone of South Africa.
Yuanansuchus is an extinct genus of mastodonsauroid temnospondyl. Fossils have been found from the Xinlingzhen formation in Yuan'an County, Hubei, China and date back to the Anisian stage of the Middle Triassic.
Chelydrops is an extinct genus of Chelydridae from Miocene of North America. Only one species is described, Chelydrops stricta.
Oligopleurus is an extinct genus of prehistoric bony fish that lived during the Kimmeridgian stage of the Late Jurassic epoch.
Dinochelys is an extinct genus of paracryptodiran turtle from the Late Jurassic Morrison Formation.
Brachyopomorpha is a clade of stereospondyl temnospondyls within the infraorder Trematosauria. It was constructed in 2000 to include Bothriceps australis and the superfamily Brachyopoidea. It is phylogenetically defined as a stem-based taxon including Pelorocephalus and all taxa closer to it than to Rhytidosteus. In contrast, Brachyopoidea is defined as a node-based taxon including Brachyops and Pelorocephalus and all descendants of their most recent common ancestor. Because Bothriceps is not thought to be a descendant of that recent common ancestor and would be more basal than it, the genus is placed just outside Brachyopoidea and is considered to be a sister taxon to the clade.
Tupilakosauridae is an extinct family of dvinosaurian temnospondyls. It contains the genera Slaugenhopia, Thabanchuia, Tupilakosaurus, and possibly Kourerpeton. Tupilakosaurs are known from Texas, Greenland, Russia, and France. The earliest tupilakosaur, Slaugenhopia, is Early Permian in age while the latest known tupilakosaurs are Early Triassic in age. Derived tupilakosaurs possess embolomerous centra in their vertebrae, which are diplospondylous. They also have a deep notch in the pterygoid bone of the palate. Tupilakosaurs were aquatic, and used an undulatory mode of swimming much like that of eels.
Cerrejonemys wayuunaiki is an extinct podocnemid turtle which existed in Colombia during the Paleogene period; the Middle to Late Paleocene epoch.
Heylerosauridae is a family of mastodonsauroid temnospondyls. It was first named in 1980 to include the genera Odenwaldia and Quasicyclotosaurus. In addition to these genera, the family now includes Eocyclotosaurus and Yuanansuchus. Recent phylogenetic analyses have not found a close relationship between Odenwaldia and other heylerosaurids and place it outside the family. Heylerosaurids are generally regarded as the sister taxon of the stenotosaurids.
Larachelus is an extinct genus of xinjiangchelyid turtle known from the Early Cretaceous of Spain.
