Howdy everyone! I’m an associate graphics editor at National Geographic with a passion for prehistory and fantasy! I make cartoon creatures and trolls in my spare time. 🖥️ Thefracas.art

Check out this incredible interactive I contributed a huge chunk of animation to! The world’s tallest church was built with extremely novel and (when first planned) impossible building techniques. We showcase some of the most inspired of Gaudi’s plans! www.nationalgeographic.com/culture/grap...

Happy National Dinosaur Day! Moby turns 5 this year in November, but I couldn’t help having him be front and center on this blessed day. Made from spare turkey and pitbull DNA alongside his majority T. rex, Moby was a beloved dinosaur for years. #dinosaur #dinosaurday #Tyrannosaurus #Trex

#marchofthemammals2026 Day 2: Miaopatagium furculiferum. A top 10 Mesozoic mammal

HOT FRESH NEW ART! A two-headed Ash Drake confronts a perhaps outmatched little warband, in this illustration from the just-released Champions of Chaos for Age of Sigmar: Soulbound!

Gonna boost this, and also take the opportunity to repost some related artwork! Sloths are such incredible animals, nothing like what remains in our tropical canopies.

I feel the need to address some comments that have been popping up here and there regarding the #Eremotherium design for #PrehistoricPlanetIceAge. To people saying that our paper fully refutes a sparse coat of fur in this genus, here is what we actually say:

Orctober's coming to a close so soon...

Warhammer Wednesday! Capping off my night with a mournfang. I’ve sketched this fellow up to be more ungulate than carnivore. #warhammerwednesday #ageofsigmar #theoldworld #ogormawtribes #cartoon #mournfang #warhammercommunity

The quest for refinement, resulting in a flamboyant, Fracas-style Compsognathus. Pigeon colors took over, leading to some more stylized feathers and unnatural traits.

A freak mutation, an island population, a rainforest destination? Trolls inhabiting the Western Rainforests speciated into some of the wackiest, most diverse creatures of the jungles, eating everything from leaves to honey.

Big thanks to Michael and Dr. Butcher for helping out on this one, and so happy to see it out in the wild! Sloths first, the world next… look out for a post later diving into this graphic a bit more.

The arboreal diprotodontid Nimbadon lavarackorum for day 17 of #marchofthemammals2025. A real wierdo! #paleoart #sciart

It’s #WarhammerWednesday with a Mirebrute Troggoth! These swamp-dwelling beasts can fully regenerate from horrific injury, recovering from lost limbs and “certain” death. Painfully stupid, they are given massive clubs and ridden into battle by the tribes of swamp orruks. #warhammer #ageofsigmar

This mean, rocky monster-truck demolished my poor Kruleboyz in my last game of Age of Sigmar. Give it up for the stonehorn! #warhammer #ageofsigmar #warhammercommunity

A Tylosaurus chomping a smaller mosasaur (platecarpus) for Bluesky! 🥂

excuse me ma’am, you can’t build your nest there #pokemon #skarmory #fanart

helloo bsky! i'm here now :) hoping to find a new place to post my works and meet some cool people as well! i'm a director/art director in animation field, doing mostly paleoart in my free time, but also fanart and field sketches. i'll appreciate any support and will be happy to chat!<3 #paleoart

Wait I don't remember this classic animated film

"Onyx" The black dragon Onyx guarding her treasure hoard in the ruins of Xak Tsaroth. Painted in acrylics for the D&D 2024 Dungeon Master's Guide!

Before I moved to the DC area I had the pleasure of designing the art for The Edelman Fossil Park’s first beer can. (2022)

I wanted to create a list of artists with less than 1000 followers, but as I can't remove myself, it is less than 3000 There is some variety Creatures, paleoart, TTRPG, Fantasy, OC's etc etc go.bsky.app/SkzK7g6

Saw people were doing intros, so we're getting in on the fun. We're Steven and Elizabeth, two people who really want to tell you stuff about dinosaurs using old toys and animation. Our stuff can be found on Youtube (link in bio). We hope you like it!

Boy did I make a lot of these guys in 2021.

What happens when a mastodon in musth meets a black bear? #paleoart

A humpbacked polar dolbin, with mandibular tusk.

The most predatory dolbins drag themselves across the shorelines of coastal waters, eating everything from hoofed animals to larger fish.

LIVE ON KICKSTARTER! The Dragonslayer Codex begins. www.kickstarter.com/projects/saw...

Celebrating the final day of #Orctober with a Kruleboy! I love the chain-mace swinging orruk from the Stab Ladz (Warhammer Underworlds warband), so this is loosely based on it. #warhammer #aos #ageofsigmar #orrukwarclans #kruleboyz

#troggoth sketch - Young Stinky the Dank-cave troggoth. A future Troggboss from a marshy region of semi-submerged mountains.

All four of my illustrations for the Edelman Fossil Park’s series of dinosaur beers. Due to being a limited run, most are unavailable at this time. 🐡

A couple of spreads from a book I worked on together with the amazing @stbende.bsky.social for Star Wars… yes… that’s right… we did a Star Wars Bestiary together

Van Helsing (2004) is such a fun movie. Just absolutely nuts from beginning to end, up there with The Mummy as the perfect Halloween action flick.

Hadrosaurus - 2021 #Dinosaur

Squigs, sketched on paper and digitally filled - 2022

Prior to a short comic, I had delved into some mastodon coloration with a few realistic and not so realistic patterns.

Recently I've gotten caught up with @talesofkaimere.bsky.social's Tales of Kaimere! Really cool fantasy setting with a spec evo twist. It's gotten so firmly wrapped around my brain I had to do some takes on some of the mammals from the setting, starting off with the best ones, the sloths 🦥

I love what #comics can do. Simply putting some boxes next to each other can achieve very different things depending on what's in them. Consider how your brain - without any instruction - infers (hopefully) what's going on in these 3 different sequences regarding continuity, space & time...

Daeodon, the notorious “hell pig” from the Oligocene #Designersaur

Good morning goblins

Hello everyone! My name is Ian and I’m a freelance paleoartist specializing in dinosaurs and fossil fish. I don’t have any new (finished) art to share but here are a few WIPs and commissioned work I have sitting around!

A gallop cycle of Bos bison antiquus (otherwise known as the Ancient Bison) for the game, Ecos: La Brea on Roblox. 🦣 @ecosroblox.bsky.social 🦬 ecoslabrea.wixsite.com/ecos--la-brea

Camasaurus lentus CM11338 Portrait. Mix of traditional and Digital media, 2024.

I will post them separately since that image was destroyed by bluesky's compression

The goofiest of my creations, the dreaded dinochicken exists at the cruel whims of uncaring venture capitalists. Ethics be damned, the dinosaurs will return!
