The second largest prehistoric pinniped is Gomphotaria pugnax with a skull length of nearly 47 cm (19 in). [150] One of the largest of prehistoric otariids is Thalassoleon, comparable in size to the biggest extant fur seals. An estimated weight of T. mexicanus is no less than 295–318 kg (650–701 lb).

Iguanodon (/ ɪ ˈ ɡ w ɑː n ə d ɒ n / i-GWAH-nə-don; meaning 'iguana-tooth'), named in 1825, is a genus of iguanodontian dinosaur.While many species found worldwide have been classified in the genus Iguanodon, dating from the Late Jurassic to Early Cretaceous, taxonomic revision in the early 21st century has defined Iguanodon to be based on one well-substantiated species: I ...
Ca. 37,000-year-old cub of Homotherium latidens found near the Badyarikha River, Siberia. This is a list of Ice Age species preserved as permafrost mummies. It includes all known species that have had their tissues partially preserved within the permafrost layer of the Arctic and Subarctic. Most went extinct during the Late Pleistocene ...
List of pterosaur genera. This list of pterosaurs is a comprehensive listing of all genera that have ever been included in the order Pterosauria, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomen dubium), or were not formally published (nomen nudum ...
While the dinosaurs' modern-day surviving avian lineage (birds) are generally small due to the constraints of flight, many prehistoric dinosaurs (non-avian and avian) were large-bodied—the largest sauropod dinosaurs are estimated to have reached lengths of 39.7 meters (130 feet) and heights of 18 m (59 ft) and were the largest land animals of ...
Other rebbachisaurid features include the rather simple ("attenuated") structure of the neural spine and the respective inclinations of the centrodiapophyseal lamina and the postzygodiapophyseal laminae. Maraapunisaurus is a genus of sauropod dinosaur from the Late Jurassic Morrison Formation of western North America.
Peteinosaurus (/ p ɛ ˌ t aɪ n ə ˈ s ɔːr ə s / peh-TY-nə-SOR-əs; [1] meaning "winged lizard") was a prehistoric genus of pterosaur.It lived in the late Triassic period in the late Norian age (about 218-215 million years ago), [2] and at a wingspan of around 60 cm (24 in), was one of the smallest and earliest pterosaurs, [3] although other estimates suggest a wingspan of up to 1 m (3.3 ...
