I'm making an 8K render for large print and display use and I'm just kinda vibing with how this foot looks in high res here

Just got my hot-off-the-press copy of the new edition of Dinosaurs: How They Lived and Evolved, written by @tetzoo.bsky.social and yours truly, with gorgeous new cover art from @bobnichollsart.bsky.social: finally, a sauropodomorph on the cover πŸ¦•πŸ¦•πŸ¦• On sale soon!

I didn't have a lot of energy today but I really wanted to give the styracosaurus a go. Skipped the coloring to give myself more time to rest. :p

Black-and-white photograph of Dr. Helen Taussig, an older woman with short, wavy gray hair, wearing cat-eye glasses, a pearl necklace, and a white medical coat over a dark blouse. She stands in a clinical setting, holding up a large chest X-ray film to the light with her left hand, examining it closely with a thoughtful, focused expression as she looks slightly upward and to the side. Behind her, multiple other X-ray images of torsos and rib cages are displayed on a viewing box or light panels, illuminating the scene.

Cardiologist Dr. Helen Taussig founded the field of pediatric cardiology.

Co-developed the Blalock-Thomas-Taussig shunt in 1944. This groundbreaking surgical procedure treated "blue baby syndrome" saving thousands of infants who previously had no treatment option.

BIG NEWS: North Atlantic right whales have now welcomed 21 total calves this seasonβ€”shattering a 15‑year record!

Scientists consider 20 births to be the benchmark of a productive calving seasonβ€”a win for these animals.

Influence of water temperature, body size, condition and gull-inflicted lesions on heat loss in southern right whales in PenΓ­nsula ValdΓ©s, Argentina Summary: Warm calving waters provide limited thermal benefits to southern right whales as body size and condition ensure effective insulation, although gull-inflicted lesions can compromise it in smal...

Our recent study in the Journal of Experimental Biology demonstrates how body size and condition reduce heat loss in southern right whales & that they do not need to migrate to warmer waters to offset heat loss in their newborn calvesπŸ‹

A hidden diversity of ceratopsian dinosaurs in Late Cretaceous Europe - Nature New results indicate that rhabdodontids and the previously described Ajkaceratops are actually distinctive European ceratopsians, a group better known from Asia and North America.

Out in @nature.com today, we shake up the ornithischian family tree. Remember those weird Late Cretaceous iguanodontians, the rhabdodontids? Well they're weird because they aren't iguanodontians. They're ceratopsians. Well, at least some of them are... www.nature.com/articles/s41...

Extreme armour in the world's oldest ankylosaur - Nature The ankylosaurian dinosaur Spicomellus afer possessed a tail weapon and uniquely elaborate dermal armour.

A study published in August in Nature shows that the earliest known ankylosaurs had elaborate body armour, including a spiky ornament on their tail. These extreme armour features are unlike those of any other vertebrate, including other ankylosaurs later in their evolutionary history. #Paleosky πŸ§ͺ

I strongly encourage my palaeoart peers who work in the museum display sector to write explicit "no AI modification" clauses into their contracts.

Even if your employee contacts at a given museum are trustworthy, you can't rely on outsourced 3rd parties to not butcher your work without said clause.

Coming back from vacation to some good news!

The first baby whale of the 2025-2026 North American right whale calving season was spotted Nov 28 near South Carolina.

Mom is Champagne (ID #3904) and its her 2nd documented calf. What joyful news for a species with 384 whales remaining.

One of the best & most useful scientific figures when it comes to sauropods is this one from Jannel et al. 2022. It's visually clear & gives a good idea of which sauropods we have decent hind foot aka pes material for.

Skulls of pachycephalosaurids, generalized and only vaguely implied to specific species. 

The first two columns show the skulls of generalized pahcys in lateral (left) and dorsal (right) views, with some shading to make the domes pop a bit.

Arrows indicate the direction and trajectory of dome growth in ontogeny. In some Stegocephale-Prenocephale-morph taxa, there are accessory domelets on the side, thse pop up last in ontogeny, and are shown by smaller, accessory arrows.

The bottom row shows Dracorex, Stygimoloch, and Pachycephalosaurs as an ontogenetic series with similar arrows.

One of the largest temmnospondyls ever to exist: the gigantic Koolasuchus was also the last non-lissamphibian temnospondyl to exist. It survived into the Early Cretaceous of Australia when all other stereospondyls were long gone

After we published the new specimen of #Spicomellus a few weeks ago, we were contacted by George Blasing, who said he'd bought some on the commercial market, and wanted to return it to Morocco. It arrived last week. Thanks George for doing the right thing in the name of science!

3D model of the reconstructed skeleton of Megabalaena. The posterior skull, partial mandible, left flipper, and much of the vertebral column and ribcage are preserved.

The skull and mandible of Megabalaena. The skull is quite wide, like modern right whales, and the lower jaw is very large, and must have been about three meters long. Steepness of the braincase indicates the rostrum would have been arched like modern rights and bowheads.

Why anatomy is hard to learn for students: text books give you definitions like this -
diaphysis = shaft between metaphyses
metaphysis = the part between the epiyphysis and diaphysis
epiphysis = the part between the articular surface and metaphysis

It's like a scientific riddle πŸ˜„
