When Saber-Toothed Gorgonopsids Ruled the Earth

Inostrancevia is an extinct genus of large carnivorous therapsids, which lived 260-250 million years ago during the Late Permian in what is now European Russia and South Africa.
Inostrancevia is the biggest known gorgonopsid, with the most massive fossil specimens suggesting a size estimated between 3 and 3.5 meters in length.

Gorgonopsians inhabited Pangaea. The Karoo sediments were laid down in a sub-Antarctic environment. The supergroup lies right on top of the Dwyka Tillite, an exceptionally thick layer of Glacial sediment. If there's evidence of large eyes, they may have been hunting in polar winter, near permanent dark. The fact that the end-Permian sediments at the top of the group show evidence of hot weather shows just how insane the planetary heating was during the Great Dying.

Emilia did awesome! Great clip and can relate with the long names although I love them.

[@breacarlson2075]

I will say they do look terrifying. I would hate to come in contact with one.

[@CreatorOnline2.0]

When I was making this video, at the end, I edited the part related to the extinction of those gorgonopsians and I felt very bad that a lot of species on our planet died out due to different reasons.

Any gorgonopsians that were nocturnal, are reasonably likely to have been mesotherm or endotherms. Most ectotherms are diurnal, since the best source of heat for them is sunlight. This is important because of the question of whether these Proto mammals had developed such mammal-like traits as endothermic and hair, yet.

[@andrewstrongman305]

How does an animal with back-curving teeth, well back from the front of the jaw, use them for slashing? I think they would be more effective at stabbing attacks into vulnerable areas, biting down and ripping back would cause the victim massive blood-loss.

[@whyitmatterstome]

How do we know Gorgonopsids didn't have floppy ears?

[@CreatorOnline2.0]

That is a big question!

[@chancegivens9390]

I don't see why they wouldn't!

[@andrewfong894]

Because they didn't have the complex inner ear structure of true mammals

There is no such process called "rule the Earth". Life on Earth is a synergistic process. The synergy and respect wildlife has for one another is ubiquitous. The idea that because an animal is a predator they "rule" is a juvenile notion without a shred of evidence.

Gorgonuptus Draculus didn't live too far away from the water..hunting in and out of it. Maybe a stalker or a peeping tom🤔
