Homo erectus from Java

Anomalocaris (from Ancient Greek , meaning "unlike", and , meaning "shrimp", with the intended meaning "unlike other shrimp") is an extinct genus of radiodont, an order of early-diverging stem-group marine arthropods. It is best known from the type species A. canadensis, found in the Stephen Formation (particularly the Burgess Shale) of British Columbia, Canada. The other named species A. daleyae is known from the somewhat older Emu Bay Shale of Australia. Other unnamed Anomalocaris species are known from China and the United States.

Cryptoclidus ( ) is a genus of plesiosaur reptile from the Middle Jurassic period of England, France, and Cuba.

Purussaurus is a genus of extinct giant caimans that lived in the Americas during the Miocene epoch, from the Friasian to the Huayquerian in the SALMA classification. It is known from skull material found in the Brazilian and Peruvian Amazon, Argentina, Colombian Villavieja Formation, Panamanian Culebra Formation, Urumaco, and Socorro Formations of northern Venezuela.

Borophagus ("gluttonous eater") is an extinct genus of the subfamily Borophaginae, a group of canids endemic to North America from the Middle Miocene to the early Pleistocene (12—2Mya).

Astraspis ('star shield') is an extinct, monotypic genus of primitive jawless fish from the Ordovician of Central North America including the Harding Sandstone of Colorado and Bighorn Mountains of Wyoming. It is also known from Bolivia. It is related to other Ordovician fishes, such as the South American Sacabambaspis, and the Australian Arandaspis.

Aigialosaurus is an extinct genus of Late Cretaceous marine or semiaquatic lizard classified as part of the family Aigialosauridae within the Mosasauroidea. Exclusively found in deposits of Cenomanian age near Hvar, Croatia, the genus contains one valid species, A. dalmaticus. According to recent molecular and morphological data, Aigialosaurus is the oldest known member of the lineage leading to large Cretaceous marine reptiles called mosasaurs, a group most closely related to snakes among living squamates. It was a relatively small reptile with a complete specimen measuring long.

Eunotosaurus (Latin: stout-backed lizard) is an extinct genus of reptile of disputed affinities. It is known from the late Middle Permian (Capitanian stage) of the Karoo Supergroup of South Africa and the Mwesia Beds of Malawi. Its ribs are wide and flat, forming broad plates similar to a primitive turtle shell, and the vertebrae are comparable to those of some turtles. Accordingly, Eunotosaurus has often been considered as a possible transitional fossil between turtles and their prehistoric ancestors. However, it is possible that these turtle-like features evolved independently of the same fe

alt=Coniophis sp. snake vertebra|thumb|Coniophis sp. vertebra Coniophis is an extinct genus of snakes from the late Cretaceous period. The type species, Coniophis precedes, was about 7 cm long and had snake-like teeth and body form, with a skull and a largely lizard-like bone structure. It probably ate small vertebrates, such as lizards and salamanders. The fossil remains of Coniophis were first discovered at the end of the 19th century in the Lance Formation of the US state of Wyoming, and were described in 1892 by Othniel Charles Marsh. For the genus Coniophis, a number of other species

Picrocleidus is an extinct genus of plesiosaur from the Middle Jurassic Oxford Clay Formation (Callovian stage) of the United Kingdom.

Tetraclaenodon was a genus of small and early ungulate mammals that was part of the Phenacodontidae family. It is the oldest and most primitive phenacodontid. Its fossils known from the Nacimiento Formation, New Mexico. In 2012, Tetraclaenodon was defined as the basalmost member of the clade containing "Phenacodontidae" and Altungulata. alt=fossil skull of early ungulate Tetraclaenodon puercensis|left|thumb|Life Restoration

Geikia is an extinct genus of dicynodont therapsids from the late Permian. The abundance and diversity of dicynodonts during this period, combined with incomplete or inadequately prepared specimens, have led to challenges in determining relationships within this taxon. Only two species, Geikia locusticeps and Geikia elginensis have been assigned to this genus. While this is the currently accepted classification, fossil record limitations have led to repeated debate on the genus assignments of these species.

Claorhynchus (meaning "broken beak", as it is based on broken bones from the snout region) is a dubious genus of cerapodan dinosaur with a confusing history behind it. It has been considered to be both a hadrosaurid and a ceratopsid, sometimes the same as Triceratops, with two different assignments as to discovery formation and location, and what bones make up its type remains.

Cimolopteryx (meaning "Cretaceous wing") is a prehistoric bird genus from the Late Cretaceous Period. It is currently thought to contain only a single species, Cimolopteryx rara. The only specimen confidently attributed to C. rara was found in the Lance Formation of Wyoming, dating to the end of the Maastrichtian age, which ended about million years ago. The dubious species "Cimolopteryx" maxima has been described from both the Lance Formation and the Hell Creek Formation of Montana. The humeral end of a left coracoid from the Frenchman Formation of southern Saskatchewan has also been attribut

thumb|left|220px|Head of Pontosaurus kornhuberi Pontosaurus is a now extinct genus of pythonomorph from the Late Cretaceous period. The type species, P. lesinensis, is from Hvar in Croatia. It was originally named Hydrosaurus lesinensis and placed in the genus Hydrosaurus Wagler, 1830, which is preoccupied by the agamid genus Hydrosaurus Kaup, 1828, and now considered a synonym of Varanus, but later placed in a separate genus Pontosaurus. A second species, P. kornhuberi, is known from the Sannine Formation in Lebanon.
