A very robust (like a chonky cat) but reptilian looking creature with a head that looks too small for the body. 4 legs and a short tail. The beast has a strong camouflage style of dark stripes with a pale lined edge and a lighter shade in between. The beast is stood on a sandy area with a couple of thin plants.

Macungo et al. present a new middle #Permian gorgonopsian, Jirahgorgon ceto, from the Abrahamskraal Fm of South Africa 🇿🇦 - its large size suggests the emergence of large #gorgonopsians earlier than expected!

I hate the Introduction, it implies that Modern #Mammals descended from other lineages of #Synapsid cousins that died off long beforehand, despite the fact that we are #Therapsids.

A gorgonopsid-like creature covered in white plates and fur, with colorpoint markings, is lying atop of a rock. Below the rock is a little piece of clear lake water with red lotus flowers scattered around. The creature is growling, its muzzle snarling, its claws clenching the rock it is perched upon.
A comm for @kselenavonta.bsky.social with a majestic creature! It is a dreptann, a closed species based off gorgonopsids!

A big inflatable inostrancevia with colorful stripes in a living room. Looks well-inflated and friendly. Like a saber-toothed, block-headed barrel.
I haven't had the energy to put up a toy lately, but that needs to change. Tomorrow I will come home from work and flop on the #gorgonopsid.

Inostrancevia was a #gorgonopsian - a group of highly successful non-mammalian #synapsid carnivores that existed through much of the #Permian. They were among the first terrestrial predators that specialised in killing & eating large prey, evolving large "sabretooth" canine teeth.

Dinocephalians sit on the #synapsid branch of the animal evolutionary tree, making them distant relatives of mammals. Dinocephalians were one of many clades of synapsid that diversified in the mid-late Permian that are collectively together known as #therapsids.

I remember as a kid thinking Dimetrodon was a dinosaur, only later to learn it is NOT! Dimetrodons were a type of synapsid, not related to dinosaurs at all!

Fossilized mammal tooth of a Squalodon or shark-toothed dolphin.
A fossilized tooth, possibly a squalodontid or Squalodon sp. from the Bone Valley Member, Peace River Formation in the phosphate mines of Florida, USA. These oddly toothed cetaceans are also known as shark-toothed dolphins. #FossilFriday

I just argued for 10 minutes on Discord about whether the Edaphosaurus is a synapsid (correct) or a therapsid (incorrect).
It's a Linux server.
Granted, I started the poll for best dinosaur that included the Edaphosaurus as a joke vote, with clear indication that it's not a dinosaur, but still […]

Here’s a #Dimetrodon skeleton on display at the @romtoronto.bsky.social 🇨🇦 for this #FossilFriday. This ancient forerunner of mammals was one of the top carnivores on land during the early #Permian, long before the dinosaurs.

Dimetrodon was a sail-backed, prehistoric reptile from the Permian period, known for being a top predator. Though often mistaken for a dinosaur, it's more closely related to mammals.

might remake this one, really like the patterning I gave it

Two Cotylorhynchus (large Permian synapsid) walking up to the entrance of a cave after a long walk, only to find out that the entrance is ironically blocked off by collapsed debris, possibly from strong winds in the desert?
New post: The Barrel Beast - Cotylorhynchus
A pair of chunky synapsids get stuck on a dead end of what should be the cave's entrance.
I tried to get it done while watching JW: Dominion because I wanted to rewatch/finish the movie for some reason.
