Thylacosmilus is an extinct genus of saber-toothed metatherian mammals that inhabited South America from the Late Miocene to Pliocene epochs.Though Thylacosmilus looks similar to the "saber-toothed cats", it was not a felid, like the well-known North American Smilodon, but a sparassodont, a group closely related to marsupials, and only superficially resembled other saber-toothed mammals due to ...

[47] [49] The ears are rounded and the eyes have a round pupil. [47] The snout ends in a triangular, pink tip with small black dots, the number of which increase with age. [50] The tiger's skull is robust, with a constricted front region, proportionally small, elliptical orbits, long nasal bones and a lengthened cranium with a large sagittal crest.
Size comparison between a person and Inostrancevia (reconstructed with long lips and some hair). Earlier gorgonopsids in the Middle Permian were quite small, with skull lengths of 10–15 cm (4–6 in), [1] whereas some later genera attained massive, bear-like sizes with the largest being Inostrancevia up to 3.5 m (11 ft) in length and 300 kg (660 lb) in body mass.

The biggest skull of a Siberian tiger from northeast China measured 406 mm (16.0 in) in length, which is about 20–30 mm (0.79–1.18 in) more than the maximum skull lengths of tigers from the Amur region and northern India, [11] with the exception of a skull of a northern Indian tiger from the vicinity of Nagina, which measured 413 mm (16.25 ...
A 13,600-year-old mastodon skull was uncovered in an Iowa creek, state officials announced this week. Iowa's Office of the State Archaeologist said in a social media post that archaeologists found ...
Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in every continent except for Australia and Antarctica. The earliest species is known from the Middle Miocene, while the latest species Smilodon populator survived up to the Early Holocene (8,200~9,100 years ago).
