Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Late Pleistocene or Early Holocene – and before recorded history, specifically before they could be studied alive by ornithological science. They had died out before the period of global scientific exploration that started in the late 15th ...
E. mealsi reconstruction and size comparison . It had a short tail and developed limbs with webbed feet. Unlike modern sea lions, it had a set of slicing carnassials; the presence of slicing teeth (rather than purely piercing teeth as in modern fish-eating pinnipeds) suggests that Enaliarctos needed to return to shore with prey items in order to masticate and ingest them.
The infraorder Pinnipedia consists of 3 families containing 34 extant species belonging to 22 genera and divided into 48 extant subspecies, as well the extinct Caribbean monk seal and Japanese sea lion species, which are the only pinniped species to go extinct since prehistoric times. This does not include hybrid species or extinct prehistoric ...
The skull of Pontolis is 60 cm (24 in) long, surpassing skulls of any other prehistoric pinnipeds and twice as big as the skulls of modern male walruses. [3] This giant species was much larger than modern walrus, though like many other extinct walrus species, its upper canines did not develop into long tusks like those of the modern walrus.
Some extinct predatory telluravian birds had talons similar to those of modern birds of prey, including mousebird relatives (Sandcoleidae), [6] and Messelasturidae indicating possible common descent. Some Enantiornithes also had such talons, [ 7 ] indicating possible convergent evolution , as enanthiornithines weren't even modern birds .
The Fish and Wildlife Service just delisted 21 species from the Endangered Species Act due to extinction.
