#Lystrosaurus

[boobookittenartblog]

Lystrosaurus by John Sibbick as seen in the book Prehistoric Life - The Rise of the Vertebrates by David Norman (1994).

“For a long time it was supposed that the large Early Triassic dicynodont Lystrosaurus was a lumbering, hippopotamus-like creature that wallowed in streams and waterholes. But recent work has suggested that it was a land-dwelling creature with a lifestyle not unlike that of a modern pig.”

Nature, 252 mya: LYSTROSAURUS SWEEEEEEEEEEEEEEP

[thicctails]

More Jurassic Sap Hole AU! This time, we've got Spinosaurus Fiddleford, Stegosaurus Soos, and Lystrosaurus Gideon.

Bonus lil Fiddauthor sketch:

anyways, feel free to leave some suggestions for what other characters to be! Im (jokingly) considering Anomalocaris for Bill and (not jokingly) considering Maiasaura for Melody

Doodled a Lystrosaurus

Based on a lystrosaurus my friend and I had in ark named metchup that died to a sarco… rip metchup

L is for...?

All of the L names in my Paleo Party! Are there any I'm missing? (Lokiceratops is coming I promise!!)

A Lystrosaurus and her calf. She's been in a lot of fights to protect her kids.

They're not known to have fur, but I put little tail tuffs anyway, since mammals with similar skin (like elephants) have them.

Portrait of Lystrosaurus maccaigi, a species of the morphologically-diverse Dicynodont genus Lystrosaurus that hails from the Lystrosaurus Assemblage Zone of South Africa’s Karoo Basin.

"The advanced paramammals, the theraspids, evolved some 50 million years after the early flesh eaters. Giant lumbering plant eaters such as Moschops were forerunners of dicynodonts such as Lystrosaurus and Dinodontosaurus. Fierce flesh eaters such as Titanosuchus were ancestors of both the cynodonts (Thrinaxodon and Cynognathus) and the bauriamorphs (Bauria). Furry, warm-blooded flesh eaters, these were only a step away from being mammals. Morganucodon, the first true mammal, evolved around 200 million years ago."

Fossil Friday : Lystrosaurus

Talk about a face only a mother could love. Lystrosaurus may not be the prettiest animal but it is an incredibly important one. Discovered in 1870 by Dr. Elias Root Beadle, he tried to reach out to Othniel Charles Marsh who unfortunately never responded. So, Beadle reached out to Edward Drinker Cope who described and named the animal.

Lystrosaurus is a dicynodont therapsid, a group of non-mammalian therapsids. It wasn't very big, averaging about 3 ft in length. Like other dicynodonts, it had a very short snout that may have ended in a hory beak. It had only two tusk-like teeth at the front of the mouth. It had weak jaw joint and moved backward and forward in a shearing motion rather than up and down.

It moved with a semi-sprawling gait and it's massive forelimbs suggest it was a powerful burrower.

In 2022, a mummified Lystrosaurus was found in the Karoo Basin in Africa. It showed dimpled, leathery, hairless skin.

The most incredible thing about these animals is when and where they lived. It lived from the Late Permian through the Early Triassic. That means it survived the Great Dying, the biggest extinction event the Earth has seen.

How did it do this? We're not sure but there have been a few ideas put out:

it was really god at hibernating

it could burrow and avoid the worst of the extinction event

it was semi-aquatic

it was not specialized for certain foods

shortage of predators

he got lucky

As you can see, lots of ideas have been thrown around but nothing concrete yet has been found. We're still not entirely sure what caused the extinction either which makes things difficult.

The other big deal about this animal is where its fossils have been found.

Currently, these countries are pretty far apart but if we put them together:

We can see that it makes sense why we find Lystrosaurus where we do.

Tune in Monday for an in depth look at the Ring of Fire! Have a good weekend and fossilize you later!

Some of my favorite permian period creatures:

- GORGONOPSIDS

- Coelurosauravus

- Eryops

- Dimetrodon

- Lystrosaurus

- Scutosaurus

Also Heliocoprion gets a shoutout here because of how terrifying that creature looked.

What are your favorite ancient Permian creatures?
