Today’s four random pieces of palaeoart:

@maijakarala.bsky.social’s Platyhystrix, @chrisdipiazza.bsky.social’s Cryolophosaurus, Arthur Hayward’s Styracosaurus, and Ely Kish’s Triceratops!
A deep grey and white countershaded Platyhystrix standing in a wide stanced posture. Its sail has a messy streak of red at its middle point. A slender, purplish Cryolophosaurus with a yellow underside and white-banded tail feeds on a small, blue-grey sauropodomorph. A squat, turtle-beaked Styracosaurus with wrinkled, toad-like skin stands before a meadow of red wildflowers. A herd of wide-stanced Triceratops with short horns and slick blue skin trundle across a sandy beach. In the distance, huge bird-like pterosaurs soar over the sea.

I saw your profile and I liked your style very much!! ^^

Some of my art:
Pencil sketches on paper featuring a Rhinoceros and a Black Caiman (Jacaré-Açu). The photo includes several prehistoric creatures: an Ubirajara displaying its unique ornamental feathers, a Therizinosaurus with its long-clawed arms, and a Carnotaurus bust with prominent horns. Also depicted are a Dodo bird bust, the head of the carnivorous dinosaur Maip, and the head of a Macrauchenia. The drawings focus on anatomical details Colored drawings on cardboard: Hybrid Pumpkin-Alligator in the top-left corner. Hallucigenia (spiky worm-like creature) in the center. Struthiocephalus (horned beast) in the bottom-center. Platyhystrix (sail-backed amphibian) in the middle-right. Titanophoneus (robust therapsid) in the top-right corner.

Metri has been a blast to play after the TLC. Mine has carved out a niche in the Arazoa ecosystem with a diet mainly consisting of mushrooms, carrion, snakes, and Platyhystrix. Population control 🔥

A bunch of paleontology-inspired dragon critters from a few years back. Which one would you like as a pet? Somehow, I have a soft spot for the turqoise-eyed weirdo.
A tiny leaf green dragon-like creature with round orange eyes, moth-like antennae and dragonfly-like wings. A moss green, swimming dragon-like creature with a large sail on its back, similar to that of the extinct temnospondyl amphibian Platyhystrix. A somewhat sad-looking brown dragonlike creature with large wings on its hindlimbs instead of forelimbs, similar to the Triassic reptile Sharovipteryx. A small, slightly unhinged-looking dragon creature with vaguely amphibian features, long skinny legs and wings tucked into the forelimbs as in pterosaurs. It has large turqoise eyes staring at nothing in particular.

Dimetrodon attacks a congregation of breeding Platyhystrix. Edaphosaurs watch. It's really intriguing to me how all of these Permian Southwestern animals convergently evolved sailbacks.

Dimetrodon, a grand sailbacked synapsid, crashes the party of some unfortunate Platyhystrix that swim away frantically. In the back, several Edaphosaurus watch.

Looks like it's that time of the year to pull this out again (with updated speen art)

"Show me the best"/"Perfection" meme with Michael Fassbender showing three sail-backed tetrapods, the new Spinosaurus mirabilis (art by Dani Navarro), Dimetrodon (art by Danielle Dufault), and Platyhystrix (art by u/SaurArch on Pinterest), from top to bottom. Corresponding text is "show me the best sail-backed tetrapod" (Spinosaurus), "I said the best sail-backed tetrapod" (Dimetrodon), and "perfection" (Platyhystrix)

TIL about platyhystrix! (Looks like the name has an accidental capital L)

Spectacular work! I love all these big headed weirdos!

Part of that revision of Aspidosaurus was then published in my redescription of Aspidosaurus novomexicanus from the Permo-Carb of New Mexico - I designated this as a nomen dubium because it's too poorly preserved to diagnose (though it could be another known dissorophid): doi.org/10.26034/la....
Photograph and interpretive line drawings of the holotype of Aspidosaurus novomexicanus, a dissorophid from the Permo-Carboniferous boundary of New Mexico. The specimen represents a partially articulated skeleton, with the back half of the skull and most of the presacral column preserved, but it is badly preserved, with most surface details weathered off and the loss of various osteoderms, ribs, and neural spines. Other features like the centra are not clearly exposed but are likely contained within the block. The first line drawing is my interpretive line drawing for this paper; the second is the original interpretive line drawing from Carroll's (1964) redescription in which various features / details cannot be corroborated. Photograph and interpretive line drawing of the osteoderms and associated axial elements of the holotype of Aspidosaurus novomexicanus. The osteoderms are of varying preservational quality and appear to be a single series, each wider than long, with separation between each position, but as this does not occur in any other taxon other than the peculiar Platyhystrix, this is interpreted as post-mortem loss of a second, external series.

Robert Bakker's Platyhystrix and captorhinids!
A sail-backed Platyhystrix strides over a sand dune, carrying a lizard-like captorhinid in its mouth. Two other captorhinids peer from their burrows, surveying the carnage.

no no no dim dims are too big they threaten the bugs. i appreciate the sails but i'd rather keep them as small as platyhystrix

I see a Permian enjoyer, so here's some Permian art!
Prionosuchus eggs hatch under the full moon. Helicoprion peeks out of the water at dawn to look at some blowing leaves. Two Estemmenosuchus watch as their young play around in a puddle of meltwater. Dimetrodon ambushes a group of Platyhystrix.

Platyhystrix was one of the many - curiously, unrelated - animals with a sail from around this time. Was it a thermoregulation device? An ornamental feature to impress mates? Maybe both? Regardless, it probably didn't make hiding from predators any easier.
Side view illustration of Platyhystrix (name meaning "flat porcupine": a clumsy-looking vaguely amphibian animal with splayed limbs and a tall sail-like structure on its' back.

Clumsy Hunter

In the early Permian, a little less than 300 million years ago, life on land had long been rich and diverse, but most of the animals were still a bit... goofy.

Here's Eryops chasing down a Platyhystrix in a lush riverside forest in what is now Texas, some 290 million years ago.
Colourful illustration of a forest scene in which a large, blue-grey vaguely salamander-like animal is running somewhat comically, it's maw open to grab a smaller, sail-backed animal that is escaping up a fallen tree trunk. The ground is covered by mosses, dead leaves and ferns, with several insects and millpedes around.

3 pieces to get to know me.
#art #myart #artistonbluesky
A variety of Platyhystrix, sail-backed salamander-like creatures, panickedly swim away from a marauding Dimetrodon, a large, gray animal with a reddish fin on its back and sharp teeth. Edaphosaurus, bluish sail-backed animals, gawk in the background. It is dawn. Realistically-styled Volcarona, Jellicent, Haxorus, Excadrill, Mienshao and Ferrothorn A river cuts through a landscape, passing by a variety of different ecosystems; a mountainous region, a chaparral, a park, a forest and a tidal marsh.

Latest #watercolor is the weird (saying a lot by amphibian standards) temnospondyl, #Platyhystrix. The crest on the back is made of elongated armor plates, not extended vertebra like most other sailbacked animals. #paleoart

From 2017: Platyhystrix wanders out of a Permian swamp next to the roots of a fallen tree. This ancient dissorophid #amphibian is only known from its sail, so the closely related genus Cacops provides the rest of the body. #paleoart #fossil #paleontology #sciart
A sail-backed amphibian with a frog-like face and compact body emerges from a swamp alongside the root network of a fallen tree. The animal's sail has radiating ridges with red areas near the edge, and the body is mottled with white stripes along the belly and tail. An orange band extends from the head along the entire body. Trees and thick vegetation clutter around the water margin, with more trees and low hills visible in the distance.
