A hypothetical earliest Tylosaurine, just after the split with Plioplatecarpines. No fossils of such basal Tylosaurs are known, but based on other early #Mosasaurs it’d be leggy and noodly. Inspired by @tyrantlzrdqueen.bsky.social’s research/discussion on the Skeleton Crew. #sciart #paleoart #lizard
A colored-pencil drawing of a slender and sinuous early Tylosaurine mosasaur on a white background. Its head is slender and sharply pointed, with a streak of yellowish orange running along the upper lip. The lower jaw is a sickly green, as is the tail (also marked by vertical stripes). Its mouth is open and the small, pointed teeth of the lower jaw are visible. The rest of the body is a dull tan with faint, disorganized speckles. The limbs are relatively short and the hands and feet form relatively broad, webbed paddles with visible digits and claws. The tip of the curling tail is formed into a modest paddle, with a very short upper lobe. This is a speculative and hypothetical depiction, as no such fossils of early Tylosaurs are known but by the laws of biology and phylogenetics it must have existed at some point.

Hadrosaurus foulkii, the first dinosaur discovered in North America and one whose holotype is housed at the currently-threatened Academy of Natural Sciences in Philadelphia. If the academy is shut down, this and thousands of other irreplaceable specimens will likely be lost. #SavetheAcademy #sciart
A colored-pencil drawing of the hadrosaurid dinosaur Hadrosaurus foulkii, in a walking pose at an angle away from the viewer and towards the left side of the page. Much of the body is a warm brown, separated by a darker squiggly line from the pinkish grey back. Its head is turned slightly towards the viewer, and a thin black tear marking extends down from its eye.

At the beginning of the month Drexel University made public that they want to close the Academy of Natural Sciences at the end of the month. The academy is the oldest natural history museum in the Americas and this would end more than 200 years of research and outreach.

New idea: in the late Cretaceous this clade of Tritylodonts would have developed a muscular lip-pad as a digging/soil-foraging tool, and then right after the k/pg it gets elongated and co-opted for browsing until you could reasonably call it a trunk. #specevo #cynodont #cretaceous
A black-and-white pencil sketch of a small, fluffy, gopher-like Tritylodont cynodont with a very silly face. Its upper lip is extended and has a large pointed pad on the end. A rough black-and-white sketch of a much larger, sort of Pantodont-like descendant of the Tritylodont in the previous drawing. The elongated upper lip is now even longer, approaching the shape of a trunk. Its mouth is open and the four tusk-like front teeth are visible.

In the woodlands of late Triassic Tanzania, a resting Dinodontosaurus isiyavamanda is run over by two small dinosaurs (it couldn’t care less). Inspired by the very recent publication of this new African dicynodont, and the @skeletoncrewpaleo.bsky.social video about it! #sciart #paleoart #mesozoic
Black-and-white pencil drawing of a Dinodontosaurus isiyavamanda (a fairly large, bulky dicynodont with prominent tusks) laying down on its belly mostly facing the viewer. Its forelimbs are arched forward and outward on the ground, tipped with robust hands and five curved claws. Its head is raised, and its small dark eyes do not reveal the presence of even a single braincell. A tiny fluffy dinosaur is mid-stride as it runs atop the dicynodont’s rotund body, chasing after another tiny fluffy dinosaur just in front of it.

A commissioned lineup of the proboscideans of Sukaya (the Africa-equivalent continent of a friend’s #worldbuilding project). Elephants are definitely becoming some of my favorite animals to draw! #specevo #Tyrannoc #elephants
A size-chart lineup of colored-pencil-drawn  elephants, all in lateral view facing towards the left side of the image against a white background. The first two are the real African Forest and African Bush elephants, the next is a species of African Mammoth, then a large species based on Palaeoloxodon recki, then a deinothere based on Deinotherium bozasi, and then a much, much larger species with four tusks that is entirely fictional (it specializes on browsing magical trees in this worldbuilding setting). All are some variation of brownish grey, with the forest elephant being notably darker and the deinothere possessing a slightly rusty-colored dewlap under its throat and chest.

Where a river empties into the Sundance Sea, one of the first Gars cruises past rows of horsetails while an early Brachiosaurid approaches the shore. A speculative scene inspired by talking with @seismic-shrimp.bsky.social about the origin of Lepisosteidae. #paleoart #sciart #sundayfishsketch #gar
A colored pencil drawing of a half-underwater scene in western North America during the late Middle Jurassic. The water is brown and murky, darkening towards the sandy bottom. In the foreground is a small, relatively short-faced basal Gar resting in the water column. It is greenish brown with yellowish fins and faint horizontal stripes along the head and body. Its tail is partially obscured by the dense bundle of half-underwater horsetails that frames the right edge of the drawing. The surface of the water is still and reflects the background, which is comprised of a horsetail-lined shore, two large and low pale sand dunes, and a tall sauropod dinosaur walking towards the water from between the dunes.

As much as the genus as a whole is mentioned/depicted tangentially, most of the various species of Stegodon still feel very underrated to me. Like Stegodon ganesa. The cranium is four feet long, and it hails from the Plio-Pleistocene Siwalik deposits of northern India. #paleoart #sciart #pleistocene
An original figure illustration from the old paper Fauna Antiqua Sivalensis, depicting the partially-reconstructed cranium and reattached tusks of Stegodon ganesa in dorsal view and in angled front view, labeled as “Elephas ganesa”.The same skull in dorsal view as in the first image, but with the bent left tusk slightly re-angled in photoshop to be symmetrical with the right tusk. All on a white background.A quick black-and-white pencil sketch of the head of Stegodon ganesa in front/dorsal view (minus the ears), drawn over the skull with a re-angled left tusk in the previous image.

Ichneumonid wasps A few wasps I've seen in recent years. These parasitoid insects are incredibly diverse, yet poorly known with possibly as little as a quarter of living species even named. They're famous for making Charles Darwin doubt the existence of God simply by existing in nature.
A collection of seven parasitic ichneumonid wasps of different shapes and sizes, drawn with white on a black background. Most are of unknown (to me) species, though the large one in lower right corner is a sabre wasp (Rhyssa persuasoria), a parasite of large wood wasps and longhorn beetles.
