Archaic Gorgons typically have snaky hair either with snake-like curls (Figs. 8, 9), or actual snakes protruding from their heads (Figs. 2, 5, 6, 10). The faces of Archaic Gorgons are particularly distinctive, typically with large menacing eyes, tripartite scroll-like noses, wide mouths with rictus-like grins or grimaces, lolling tongues, fangs ...
Hippopotamus gorgops is an extinct species of the genus Hippopotamus known from remains found in Northern Africa, Eastern Africa, and the Levant.One of the largest hippopotamus species, it first appeared during the late Pliocene-Early Pleistocene, and became extinct during the early Middle Pleistocene.
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.

More than 99 percent of all species that ever lived (over five billion) [1] are estimated to be extinct. [2] [3] Estimates on the number of Earth's current species range from 10 million to 14 million, [4] with about 1.2 million or 14% documented, the rest not yet described. [5]
The pattern varies, and the colours can vary regionally. The arms are usually white to pale grey with black stripes. Disc can be up to about 200mm diameter with extended arms up to 500mm long, Often found on high points of a reef or up on sea fans, noble corals or sponges when feeding. Found on reefs from below about 10m to about 90m. [2] [3]
Size compared to a human. The almost complete Viatkogorgon holotype specimen is about 80 cm (31 in) long, including the skull. The skull is 14 cm (5.5 in), the preserved part of the tail is approximately 17 cm (6.7 in), the forelimb is approximately 24 cm (9.4 in), and the hindlimb is more than 26.5 cm (10.4 in). [3]
It also has an "accessory air-breathing organ" on its dorsal area, allowing it to live on dry land for up to six days. They are even thought to hibernate in mud and wait for water to return.
The genus 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. [2] Five Gorgonocephalus species were discovered from European waters, specifically four occurred in Scandinavian waters. The ...
