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.

Gorgonops (from Greek: Γοργών 'Gorgon' and ὤψ 'eye, face', literally 'Gorgon eye' or 'Gorgon face') is an extinct genus of gorgonopsian therapsid, of which it is the type genus. Gorgonops lived during the Late Permian ( Wuchiapingian ), about 260–254 million years ago in what is now South Africa .

The scapula (shoulder blade) was 7 cm (2.8 in) long, nearly 1 cm (0.39 in) wide at the joint with the humerus (upper arm bone), and its upper edge expanded to a width of 2.5 cm (0.98 in). A relatively low crest extended along the hind edge of the bone's lower third, and slightly deviated at the front from the edge of the scapula.
Wikipedia uses several templates that self-update every day to keep date and age information current. These are very useful for a dynamic online encyclopedia and save users from having to regularly update that kind of information. However, when using this kind of template, a few things should be kept in mind.
Some may live for over 1,000 years. [78] [79] The Greenland shark had been estimated to live to about 200 years, but a study published in 2016 found that a 5.02 m (16.5 ft) specimen was between 272 and 512 years old. [80] [81] That makes the Greenland shark the longest-lived vertebrate. [82]
Members of this genus are found in coldwater environments including the Arctic, the Antarctic, and deep-sea habitats. The scientific name comes from the Greek, gorgós meaning "dreaded" and -cephalus meaning "head", and refers to the similarity between these echinoids and the Gorgon's head from Greek myth with its coiled serpents for hair.
