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.
They ranged from 1.2–2 metres (3.9–6.6 ft) long from nose to tail. Gorgonops would have been one of the key predators across southern Africa during the Late Permian . Because the canines were so large, they would have had little trouble in penetrating the tough hides of some of the herbivores of the time, particularly pareiasaurs such as ...
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 ...
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]
At long irregular intervals, Earth's biosphere suffers a catastrophic die-off, a mass extinction, [9] often comprising an accumulation of smaller extinction events over a relatively brief period. [10] The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes.
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.
Dinogorgon is a genus of gorgonopsid from the Late Permian of South Africa and Tanzania.The generic name Dinogorgon is derived from Greek, meaning "terrible gorgon", while its species name rubidgei is taken from the surname of renowned Karoo paleontologist, Professor Bruce Rubidge, who has contributed to much of the research conducted on therapsids of the Karoo Basin.
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]
