Triassic non-marine horseshoe crabs,

many ancestors of today's marine animals find refuge in brackish environments, as the Permian Great Dying caused the sea to become anoxic and choked most of the marine life at the time

more dinovember friends :)

wow ignore that i havent posted here since last year. ANYWAYS !!!! somehow i forgot to post these guys alongside my Megaraptor i drew in november so 😭 here's some more fandinos for Paleo Pines !!!

"fandinos" being sorta misleading though since neither of these guys are dinosaurs lol. regardless, up first we have Tanystropheus who is infinitely ridiculous. then we have Sharovipteryx, who is equally infinitely ridiculous. both of these guys lived in the Triassic - and surprisingly, are likely related!

Results from the Besano Formation #paleostream! The middle Triassic has much to offer!

REPOST, SEE REASON BELOW

With formations like these I think it's extremely difficult to find a balance between diversity and a good composition. So although I COULD add more animal to these paintings I also want them to work on an aesthetic level. Paleoart can be more than science outreach.

I have a finally have a banner!

On this banner we have some of my favourite prehistoric animals:

Microraptor, Tanystropheus, Spinosaurus, Dilophosaurus, Confuciusornis, Sinosauropterix, Dreadnoughtus, Yi qi, tapejara and cryodrakon.

Tanystropheus? I think you mean Slizzards.

Dinocephalosaurus redescription

Check out the new paper on the redescription of Dinocephalosaurus,  long necked, aquatic protosaur that inhabited the Triassic seas of China. Wonderfully preserved specimen and while it convergently evolved a long neck similar to to Tanystropheus, instead of fewer elongaded neck vertebrae, Dinocephalosaurus has many many many shorter neck vertebrae. A bizare and wonderful necky boy of the fossil record to be sure. Art by Marlene Donnelly & Gabriel Ugueto

Tanystropheus appreciation post

[elsewhereuniversity]

They did warn me, you know. That I shouldn't take a name too true to me. That I shouldn't take a name I might change to fit. I was warned.

I'm off to the Unsea. The swim team tried, a debt I guess I won't get to repay. I did appreciate being helped through my new diet, through growing scales and webbed hands and fishook teeth. But the tail's coming in, and my neck is already creaking as the growth begins. I can't stay any longer. Give the swim team my love, and first dibs on what I've left in my room. I know I've got a gift card to the sushi place that I want them to have.

Don't follow me. Yes, I know I'm an unprecedented research opportunity for certain majors and a thesis paper unto myself. Don't follow me. I'm already losing my memories of who I know and care about. I will bite you. I will probably be too far gone to feel bad about it.

Tanystropheus

(temporal range: 245-235 mio. years ago)

[text from the Wikipedia article, see also link above]

Tanystropheus (Greek: τανυ~ 'long' + στροφευς 'hinged') is an extinct genus of 6-meter-long (20 ft) archosauromorph reptile from the Middle and Late Triassic epochs. It is recognisable by its extremely elongated neck, which measured 3 m (9.8 ft) long—longer than its body and tail combined.[1] The neck was composed of 12–13 extremely elongated vertebrae.[2] With its very long but relatively stiff neck, Tanystropheus has been often proposed and reconstructed as an aquatic or semi-aquatic reptile, an interpretation supported by the fact that the creature is most commonly found in semi-aquatic fossil sites where known terrestrial reptile remains are scarce. Complete skeletons are common in the Besano Formation at Monte San Giorgio in Italy and Switzerland; other fossils have been found throughout Europe, North America, and Asia, dating from the Middle Triassic (Anisian and Ladinian stages) to the early part of the Late Triassic (earliest Carnian stage).

Today's sketch, the magnificent, ridiculously long-necked tanystropheus. The neck could use some work, but he's definitely a long boy.

DINOVEMBER DAY 10: 240MYA, ANISIAN STAGE; ITALY

In the shallow seas of Northern Italy, a Tanystropheus and a Besanosaurus swim alongside eachother. The Tanystropheus is cautious; in the water, his companion has the advantage. He would be in by serious danger if the Besanosaurus was hungry, but fortunately for him, she has just fed and has no interest in chasing after him. For now he will hurry back to the shore, leaving her to patrol the ocean. These two strange animals are both reptiles, and they are both exemplary of the reptiles' success in the Triassic. Reptiles are everywhere: in the seas, on the shore, in the trees, digging through the soil and charging across the sands. The synapsids still hold roles on this world, but the dicynodonts are restricted to be only the largest grazers, and no cynodont is bigger than a modern badger. They are relics of a bygone age, and by the end of the Triassic, most of them will be gone.

Of the reptiles that have evolved, some groups are separating themselves from the pack. One of these groups is the ichthyosaurs, a group of oceangoing reptiles that have taken advantage of the coral reefs that have re-emerged after the devastation of The Great Dying. Besanosaurus is a typical Triassic ichthyosaur, with her sleek 8m long body ending in a paddle like tail to propel herself through the water, guided by the 4 flippers that have evolved from the arms and legs of her ancestors. She is a fast moving apex predator, but other ichthyosaurs like Shastasaurus have become 80 tonne leviathans drifting through the open oceans. Another group of animals called the sauropterygians are also making moves towards the water, with the seal-like Nothosaurus being found on beaches across Europe. One day they too will lose their land capabilities, giving rise to the long necked plesiosaurs.

On land, a group called the archosaurs have risen to power, helped by their ability to save water when they excrete, making them better suited to the vast Triassic deserts. Tanystropheus is closely related to the archosaurs, and has taken advantage of the recovering seas also; he is a fisher, using a neck twice as long as his body to grab fish from the water while his feet stay planted on the shore. He is also an adept swimmer, though not so much that he could outspeed a hungry shark or ichthyosaur. His archosaurian cousins have produced a variety of forms, fast and slow, predator and prey, but one little archosaur, far away at the other end of Pangea, has just become the first member of a group of reptiles that will surpass all others, push what is physically possible for a land animal and rule the world without question: the dinosaurs.
