The Hippidion piece by itself:

The same Hippidion scene as in the image in the post above

Tonight’s flocking-together #Paleostream was nothing but synapsids, three gorgonopsians in a row (Dinogorgon, Viatkogorgon, and Njalila) and then the Pleistocene South American horse Hippidion. #paleoart #sciart #permian #pleistocene

Black-and-white pencil sketches of four prehistoric synapsids: three different gorgonopsians in a column on the far left side of the page, and then a scene of two Hippidion taking up the rest of the space. The top gorgonopsian is Dinogorgon, rolling around on the ground happily. The middle gorgonopsian is the small Viatkogorgon, swimming above the viewer with a temnospondyl in its mouth. The bottom gorgonopsian is a bust of the newly named Njalila, just yawning. The two Hippidion that take up most of the paper are a pair of stallions fighting in the open habitats of the high Andes. One of them is in the process of kicking the other’s snout, likely breaking the long nasal bone characteristic of this genus. In the distance, a Spectacled Bear stands up to get a better view of the battle.

Vector illustration of Dynamognathus robertsoni, a large salamander from the early Pliocene of Tennessee. The long salamander is slinking along the image, with half of a tiny shrew hanging out of its mouth. It is pinkish brown in color will grey speckles along its body. Text reads: Dynamognathus robertsoni. Davis Gunnin, Blaine W. Schubert, Joshua X. Samuels et al.

Illustration of the African middle-miocene Elasmotheriine Victoriaceros kenyensis, made for the Victoriaceros Wikipedia page. The few existing reconstructions of this rhino give it a prominent nasal horn, while I depicted it with a large callus-like growth. #miocene #paleoart #sciart

A colored-pencil drawing of the elasmotheriine rhino Victoriaceros kenyensis standing in lateral view, made for Wikipedia. It is overall brown in color with pale belly and cheek. The upper lip is hooked downwards like a Black Rhino, due to it having a similar browse-dominated diet. The end of its snout sports a callus-like pad instead of a more traditionally rhino-like horn. The presence of a nasal horn is briefly stated in V. kenyensis’s description, but not elaborated upon. This is a common theme in miocene rhino descriptions, wherein a rugosity on the nasal bones is stated to be horn-bearing without a detailed analysis of any of these structures (from what I can find at least). Therefore, I decided to be more experimental with it.

A scene from middle Miocene Slovakia: a Pseudocyon rears up in surprise as a defensive mother Parvorhinus charges it, protective of her clueless calf. Parvorhinus, named a few years ago, was one of the smallest rhinos of the #Miocene and makes for a fun first sketch of 2026! #paleoart #sciart

A black-and-white pencil sketch of a small rhinoceros (Parvorhinus steinheimensis) aggressively facing, with mouth open and front foot kicked back, the bear-dog Pseudocyon steinheimensis which rears up in surprise with arms spread out. The small calf of the Parvorhinus stands right behind its mother, facing the viewer derpily.

This is not a model. This is a "fossilised" taxidermy of a Woolly Rhino, discovered in Starunia mine in Carpathian Poland (now Ukraine) in 1929. Dating to the Pleistocene, its exquisite preservation is owed to a mixture of brine, oil and clays. 🧵

The first flocking #Paleostream of 2026: speculative new discoveries that we hope to see this year. Intermediate/half-way-there pterosaur, ancestral bat, late-surviving radiodont, and arthropleura-size house centipede were the chosen prompts, which were all very fun to ponder and draw.

Four black-and-white pencil sketches of speculative prehistoric creatures, all hopeful wishes for new discoveries to be announced in the upcoming year. In the top left is a transitional/ancestral pterosaur, still rather lagerpetid-like and possessing a relatively short fourth finger, but taking off with a quad launch by the forelimbs. In the top right is a very shrew-like ancestral bat, holding a click beetle larva in its hand and jaws. In the bottom left is a vaguely horseshoe-crab-like late-surviving radiodont, crawling along the Carboniferous mud while a smaller Microsaur inspects it. In the bottom right an arthropleura-size, aquatic House Centipede rears up and to the side after being spooked by a large Sebecid, somewhere in Paleocene Africa.

Starting off 2026 with a commissions announcement! I’ve drawn a few commissioned pieces in the past, but haven’t widely advertised it before. If you would like to fund custom-made drawings from a young artist, contact me and we can discuss all the details. #commissions #paleoart #wildlifeart

An advertisement/announcement for commissions, featuring several pieces of my artwork on a dark grey background, arranged by approximate difficulty and corresponding price range. Grayscale subjects without backgrounds are roughly twenty-five to fifty dollars, colored subjects without backgrounds are roughly thirty to seventy-five dollars, infographics (either colored or grayscale) featuring text and drawings are roughly fifty to two-hundred dollars, grayscale full scenes are roughly one-hundred-and-fifty to two-hundred-and-fifty dollars, and colored full scenes are roughly one-hundred-and-seventy-five dollars to three-hundred dollars. Pricing is flexible depending on the complexity and subject matter of the piece.

Definitely one of the coolest Pleistocene papers of the past few months, common hippos in the Rhine during the middle of the most recent glacial period sounds crazy!

For my last #NearbyNature2025, I’ve drawn one of the rarest birds in North America: the Whooping Crane. They are the tallest bird on the continent at nearly 5 feet, a bit taller than the more abundant Sandhill Crane. On this New Year’s Eve, I saw these magnificent birds for the first time. #alabama
