Gigantohierax hunting Odocoileus virginianus

Megalonyx and Rangifer tarandus

Macrauchenia (with Lama guanicoe, Theristicus melanopis)

Castoroides and Ursus americanus

Two Aenocyon and Canis latrans

Haven't been as active art-wise since a lot of my time has been going into wikipedia editing since almost nobody else does ray-finned fish and early eocene mammal groups. Though some of these were done last year, most of them are from throughout 2025.

Megalonyx wanders through a flock of Clark's Nutcracker as they're caching pine nuts for the long winter. #prehistpricplaneticeage had me thinking about Megalonyx in the rockies, and I tried to extrapolate what a summer coat may look like for them. #sciart #paleoart

Manipuloyx, a new alvarezsaur with really fascinating hands! The condition of the fingers isn't that unusual for the clade but the OSTEODERMS on the hand are new!

We wish you a Merychippus, and a happy New Year! This Miocene, three-toed horse hopes everyone has a safe and cozy holiday season. 🐴🎄

My reconstruction of the Toronto Subway Deer (formerly Torontoceros hypogaeus), after a paper published this October looked at its dna and found it to be within Odocoileus, potentially a more steppe-adapted cousin of Mule Deer. #pleistocene #paleoart #sciart #canada #deer

Young Ba'khar Honor the Terms of the Tegu-Snubnose Truce. @dynamoterror.bsky.social, 2025

The pibald water monitor is a highly versatile generalist that arrived in the Seridic wetlands 1.5 mya. They're second best at everything, employing this flexibility to elbow their way between the truce established by snubnose monitors and giant tegu during the Anchored Period.

Some days ago I made a thread on Pleistocene crocs in honor of Prehistoric Planet: Ice Age, and now I'm bringing it here too. Let me prefice this by saying that I of course understand their absence, obviously more unique fauna takes priority and I don't begrudge the team their choice

The finished size chart of most of the fauna from the Mammoth Site, a Pleistocene fossil locality within an ancient sinkhole in South Dakota that preserves dozens of entrapped mammoths alongside scattered remains of other animals. #pleistocene #paleoart #sciart #Paleostream

At a forest clearing, you're greeted by the guardian, the wise old man of the forest, Gigantopithecus blacki. Recent commission of the big guy, inspired by #prehistoricplaneticeage. Although this guy is a Pongine-->

Quick sketch of Amphicyon confucianus (minus the fur) as it may have rested just before fossilization. A complete skeleton of this species exists (Shanghai Nat. History Museum has a photo of it), but it hasn’t been described as far as I know. #paleoart #sciart #miocene

this is a thread!

Megafauna are cool and all, but a habitat is only as good as its Little Guys™

Some more recent stuff than the last post: Taotienimravus, Toxodon, Xotodon, and Pakicetas #paleoart #sciart

POV: you're in the museum's Ice Age dioramas hall #SciArt #artbyjulio

For November’s #NearbyNature2025, I’ve drawn the Pecan Weevil (Curculio caryae). In the same genus as more famous oak weevils, this species lays eggs in pecans and other hickory nuts. It is native to the southeast, but is a notable agricultural pest. #bugs #sciart #wildlife #alabama

Thought I'd share a thread of artistic depictions of forests, woodlands & jungles that I find inspiring. Please reply with your personal favorites! Starting with "Ghosts of the Rainforest" - bongo illustration (Paul Augustinus) #sciart #landscape #art

Sketches from a Pleistocene-themed flocking #Paleostream! Voay robustus from Madagascar, the last species of Albanerpeton in Italy (scared by a Raccoon Dog), Mekosuchus trying to hunt a pig, and the face of the giant otter Enhydriodon. #pleistocene #holocene #paleoart #sciart

Legit thought I posted these a month ago but I forgot: Amynodontopsis jiyuanensis, Labrangomeryx dorcapolis, Leptomeryx sp., and Peraceras hessei #paleoart #sciart

Yesterday’s flocking #paleostream sketches, in shadowy forms: Lepidodendron, Baryonyx, Champsosaurus, and Genyornis. No I don’t have a favorite. #paleoart #pleistocene #cretaceous #paleozoic

“Most native Kaimeran life forms are microscopic. However-“ *slaps suction base of jiggly orb onto the table in front of you* “-the jeezhou of the Seridic wetlands is an exception. These single-celled organisms mature around the size of a golf ball, like so.”

Four species of cetacean can be found in the Seridic wetlands. Only the Seridic river dolphin (top) is a permanent resident. The other three (estuarine dolphin, river whale, and Crescent narwhal) venture with high waters during the wet season then retreat to estuaries and the gulf during dry months.

Tuatara were mistaken for lizards when first encountered by Western naturalists. Now we know they're Earth's last rhynchocephalian: a lineage related to squamates. The clade is successful in Kaimere, though only one is found in the known world: the Shezi. www.youtube.com/watch?v=STe_...

Now that SVP is over, I can finally post the commission that I did for @mosasaurologist.bsky.social 's poster on a certain very cool taxon! #paleoart #sciart

Making some fresh models to sharpen my 3D skills, and what better subject to do that than our lovely brazilian Pleistocene megafauna? #SciArt #artbyjulio

Deer are silly (making progress on the Toronto Subway Deer sketch) #pleistocene #torontoceros #deer #paleoart

My cabbages! An aurochs has broken into a vegetable garden. While curious kids and domesticated cattle watch, a courageous farmer attempts to chase it away. This scene takes place in Poland around 1400 AD. Digital painting by Peter Nickolaus, 2025.

Tonight’s flocking #Paleostream doodles: Vampyronassa being stalked by Dollocaris, Allodesmus just vibing, Papiliomaris (life size), and Pterodactylus doing a little cannibalism. #paleoart #sciart #prehistory

If any of y’all have the chance to visit this exhibition, please go see it, it’s genuinely some of the most breathtaking art I have ever seen. In a “how is an earthly being capable of creating something like this” sort of way. #art #botany

I can finally share this!!! a huge Thanks to both @skyemcdavid.com and @zhejiang0pterus.bsky.social for allowing me to do a Nyctosaur for this poster!!!

How Fridays on #paleostream feel like...

A pair of American Mastodon chow down on a (slightly fantastical) pumpkin patch 🍂✨️ #sciart #paleoart

While bovines have not spread far beyond the known world, within its confines, there are numerous species that are quite successful. Perhaps chief among these are the buffalos, with the Seridic wetlands being home to a massive population of water buffalo. Link: www.youtube.com/watch?v=hLr5...

A growing ba'khar's bread and butter:

A paper was just published that looks at the genomes of all Gibbons, forming a full phylogeny and demographic history and finding the enigmatic Junzi imperialis to be the sister species of Nomascus hainanus (Junzi is a synonym of Nomascus)!!!! www.cell.com/cell/abstrac... #primates #science #gibbons

Colored sketch of the newly-validated Nanotyrannus lancensis, though it’s not having a good time. This baby has found itself grappled by a particularly ambitious Didelphodon, after wandering a little too far from home. #backinhell #paleoart #sciart #cretaceous

A quick doodle for the final day of #GarWeek, a large melanistic Alligator Gar cruises underneath an oblivious Ocelot somewhere in the bayous of Louisiana. A scene that may have happened several times in the past, and may continue to occur if both species are valued and protected. #wildlife #sciart

Foggy morning in Late Pleistocene Patagonia. #Art #SciArt #artbyjulio

Tonight’s flocking #Paleostream sketches (it’s been a hot minute): Nanotyrannus in the woods, Pteranodon over Protosphyraena, Phosphorosaurus + sturgeon lunch, and Helicoprion. #paleoart #sciart #cretaceous #permian #backinhell
