Dwarf sauropod Magyarosaurus known from scrappy remains from Romania, but thought to be related to Saltasaurus. It's depicted here with speculative spines, and large tortoise-like spikes along the forearms. It's also very wide.

So it sure looks like the gill skeleton of Platysomus is helping process food. In this case, the position of the dentition at the front of the gill skeleton invites comparison with so-called “tongue bites” of the sort famously present in today’s bonytongue fishes. bioone.org/journals/ich...

Osteoglossomorpha were first defined on the basis of two characters: (1) the parasphenoid-tongue bite apparatus (TBA); and (2) the presence of processes associated with the second hypobranchial and/or...

. . . things like this turn up. It is, believe it or not, a great fossil of Platysomus. The head is a little distorted, but is inflated rather than totally smooshed. It’s also in an ironstone, so there’s a big difference in X-ray attenuation between rock and bone (= high contrast).
An incomplete but 3-D head and partial trunk of Platysomus. The specimen is facing toward the left, with the orbit intersected by a large horizontal crack.

here's today's #Paleostream sketches!!!

today we sketched Magyarosaurus (this is probably my best flocking sketch in a while), Pycnonemosaurus, Platysomus, and Palaeoctopus
a juvenile Magyarosaurus attempts to flee the clutches of a hungry azhdarchid pterosaur in a field of ferns, however the attempt is probably futile. Magyarosaurus is a dwarf titanosaur, a kind of long necked herbivorous dinosaur, that lived on Hateg Island, it and other dinosaurs on the island exhibited insular dwarfism, where larger animals that become isolated on islands evolve smaller sizes over time. here ive reconstructed it with osteoderms based on its relative Saltasaurus which preserves them azhdarchid pterosaurs are small to large pterosaurs that stalked small prey on the ground not unlike modern day storks and cranes, they used their long rigid necks and long beaks to snap up anything unfortunate to be within their grasp a Pycnonemosaurus kicks up dust for an unknown reason, most of its body other than its tail are obscured by the clouds. its bright yellow nasal comb and brow displays are visible through the chaos. Pycnonemosaurus is a fragmentary abelisaurid only known from parts of the tail, hip, and leg. despite this, we know it was one of the largest abelisaurids known currently, and a only somewhat distantly related to the more famous Carnotaurus a Platysomus swims through a flooded Cambrian forest floor, its surrounded by horsetails. Platysomus is a kind of ancient fish with large scales and a vaguely triangular shaped body that lived in both freshwater and saltwater a Palaeoctopus quickly swims past a deep sea camera, the outline of some rocks can be seen in the background. the animal is illuminated by an artificial light coming from behind the camera Palaeoctopus is a small extinct octopus known from Lebanon that possessed mantle fins

Platysomus (“broad body”) is a Paleozoic ray-finned fish characterized by . . . wait for it . . . a deep body. With a name referencing such an obvious feature, you’d think Platysomus–like Megalosaurus (“big lizard”) and Megatherium (“big beast”)–dates to the early days of paleontology.

13) This is 'Platysomus' schultzei, another very odd 'Bob'. I found that the original author, Jiri Zidek, was 100% correct in his anatomical interpretation. My phylogenetic analysis proved him correct in this being a Bobasatraniid, a member of an extinct, neopterygian-like clade.

#ArtBoost today is for Gael Casas @gaelcasas.bsky.social, based in Mexico. Digital artist who creates speculative creatures, #paleoart and more. Has created outstanding images of #birds and other #dinosaurs, #fossilfishes and more. Destined for greatness, and commissions open :)
Screengrab of Twitter bio. I grab these before BSky content because I post to Twitter first. Parent dodo feeding chick, both seated in nest. Extinct Carboniferous-Permian fish Platysomus. Striped, handsome, black water behind. Fossil stem-chimaera Stethacanthus as if seen at night from underwater POV. Eyes glowing, reflection on water surface.

Along with Sam Giles and others, the focus in the last several years has been Paleozoic ray-fins. Given longstanding uncertainties about Platysomus, it was a key target. But most fossils of Platysomus are flat. Devastatingly flat. “Just slide the Platysomus under the door” levels of flat.

Tonight’s flocking #Paleostream sketches: Magyarosaurus helicoptering its tail, Pycnonemosaurus rolling around with a frog, an abstract Platysomus, and a rough-sketched Palaeoctopus. #sciart #paleoart #cretaceous #paleozoic
Four black-and-white pencil sketches of prehistoric animals. In the top left is a Magyarosaurus walking (while “helicoptering” its tail) diagonally away from the viewer through an open woodland of low, shrubby trees. In the top right is a front view of a Pycnonemosaurus rolling on its side on the ground with its legs splayed out, and its head is turned towards the left as a frog sits on its snout. In the bottom left is a side-view of Platysomus, drawn in a sort of abstract way with long, overlapping straight lines forming the edges of the fish. In the bottom right is Palaeoctopus with its tentacles curled upwards partially around itself, drawn with messy, rough-sketch lines.

310-Million-Year-Old Ray-Finned Fish Had Tongue-Bite Apparatus | Sci.News
Platysomus parvulus, a species of ray-finned fish that lived 310 million years ago, had a unique way of eating never seen in ray-finned fish from that time — a ‘tongue bite’, using a special set of teeth on the floor and roof of the mouth to help it crush and chew tough food like shells or insects. Platysomus parvulus lived at the beginning of the Pennsylvanian subperiod of the Carboniferous period, 310 million years ago, at a time when a group of fish called ray-finned fish were exploring new ways to make a living.

You’d be right: Platysomus was named nearly 200 years ago.

But there are *tons* of Platysomus fossils. So if you’re determined and look long enough . . .

20-30min sketches from #paleostream flocking! Magyarosaurus, Pycnonemosaurus, Platysomus and Palaeoctopus :)
#paleoart #sciart
and some silly alt as always
Two digital sketches on one page. Top: a landscape, inspired by big murals in Moscow paleo museum (Orlov's museum), featuring Magyarosaurus, and a few pterosaurs and other sauropods in the background. Magyarosaurus there slowly goes into the water, looking down on it. The vibe is peaceful, just like a quiet sunrise in the early day during summer. Wish i was there too. Bottom: a portrait of a Pycnonemosaurus walking through a canyon, looking at the camera. The most of the animal is in shadow, but there's a hard edge of light coming from up and behind. This guy looks like he smells like dust, warm skin and a stinky dogs breath. But i love him anyway. Two digital colored sketches on one page. Top: a silly looking fish Platysomus. Just a few swimming there, some are blurred against the dark background. Two of them are close to the camera. No thoughts in their eyes at all. Bottom: a clutch of eggs, with a mother - Palaeoctopus, protecting them. You can only see a few of her arms, so it's mostly about babies. They're almost ready to hatch, and their mother is close to being forever lost in time again. Extant female octopuses die not long after their eggs hatch. And it's actually more complicated than just starvation (if you're interested - there's a lot to read about it!). I don't think we know if Palaeoctopus did that too, but i've speculated that at least they could guard their eggs too.

This kind of mechanism has evolved many, many times in actinopts. But it seems like Platysomus was the first ray-fin to figure it out. (N.B., a lineage of lungfishes were even earlier–in the Middle Devonian–because early lungfishes were evolutionary overachievers).
