A cartoon Compsognathus in expressive, piebald pigeon colors. To its left stands a previous, lower opacity sketch from which it was refined.

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

Three trolls from a rainforest biome. The Greater honey troll, Common tree troll and Giant fruit troll all occupy different niches that make use of their various proboscis. These beasts are gigantic primates, but have no external nostrils.

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.

Vector illustration of Nimbadon lavarackorum, a sheep sized arboreal diprotodontid from the middle Miocene Riversleigh Fossil Site. The animal looks like a large wombat or koala, with long arms and large claws. It is climbing up the trunk of a tree, reaching out for an adjacent branch. It is colored grey with a gradient of orange and dark brown, with irregular grey and white spots along its back

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

Mirebrute troggoths are hulking, scaled humanoids with large tusks and ears. They spend most of their time marinating in the swamp, eating carcasses and thickening their hide. When captured by the greenskinned orruks, they become mounts for the most bully riders. Despite being harnessed and driven forwards, they hold onto their weapons freely, swinging at anything they feel compelled to.

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.

The stonehorn is a massive, hooves monster that blindly charges headfirst into anything that upsets it. With brown fur, and sprawling, twisted horns, a stonehorn shears its flesh off with every collision, revealing the calcified and granite skeleton within. Usually, only the face and skin around its weapons are lost.

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

Tylosaurus grabs a smaller mosasaur, Platecarpus from the ocean surface

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

Drawing of a skarmory who has built a huge nest on top of and electric pole and also has babies there. There’s a city worker in a hard hat on a crane trying to reason with the skarmory. Neither party is pleased.

excuse me ma’am, you can’t build your nest there

A portrait of a young female megalosaurus enjoying her snack under some dead trees. Though what (or who) she's eating isn't visible, she has some blood in her mouth, and some flies are flying around. Her skin is a contrast of a large white spot from her eye to the neck, everything else is brown with a subtle tint of green.

Two juveniles unwindia are sitting on a tree, enjoying their snack - they found a dead tupuxuara, that possibly got stuck between the tree and it's branch and died not a long time ago.

A few colored sketches on one page: ammonicrinus attached on the rocks, albino benggwigwishingasuchus standing on the tree being silly and looking at their reflection in the water, simosuchus hiding from the rain under large roots, and a flock of propterodactylus surfing on a rising airflow

A ghost of Iberodactylus flying by the water surface in the night. It's right wing is touching the sea, creating a little wave and the water there glows from it's touch.

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

The VHS release for this was so good, they really knew how to make a movie back then.

Wait I don't remember this classic animated film

A black dragon perched atop a treasure hoard in a damp cave. In the background we see waterfalls pouring down onto the treasure piles, moss covers the stone ruins that hint at long gone civilization. The dragon has a pale face that makes it look skeletal, while her body is covered in black spiky plates, and her back ridged with tall spines. She has an almost serpentine look with a slender body and an enormously long tail curling back around to her front.

Fears Nothing, a dreadnoughtus pale ale, bears a large yellow and orange sauropod on its can. The beast turns to face the horizon as radiating spirals from the coming asteroid impact begin to project themselves across the sky.

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

Hell yeah, much appreciated!

Hadrosaurus posed in front of a large NJ label. The state dinosaur of New Jersey, these large animals had dainty forelimbs and thick beaks. They could likely move on their hindlimbs only to some degree.

Thank you! Sloths are definitely an under-represented group, it’s crazy just how many species are unknown to the public.

Recently I’ve been a bit slow on the paleoart, definitely something I need to pick back up. Very proud of my beer can labels however. Here’s a hadrosaurus!

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

A Designersaur is a dinosaur that has been customized for a particular patron. These curious beasts are all the rage amongst the wealthy. Pictured here: a Tyrannosaurus with baked in koi features and dragonesque touches.

Cooked in a lab, the aptly named “Dragon” DNA adds a flair only few can afford. A viral process allows features to be altered from vat-grown Stemplates® at will!

Those were based on Eremotherium, a close relative!

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!

Three swamp trolls. Scaly, slimy and made with hints of fish.

Three rock trolls. Calcified, blue skinned and happy to hurl boulders.

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

Page one of “The Confrontation”, in which a black bear happily chewing on blueberries unintentionally attracts the attention of a hormonal male mastodon. The mastodon drives the bear up a tree and begins to eat from the bush.

The bear unwittingly cracks a branch in the second page, enraging the mastodon, which attempts to knock the bear from the tree.

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

Dolbins are much like dolphins, but retain their hind limbs to some degree. They are alternative evolutionary forms sprinkled with a dash of fantasy.

A humpbacked polar dolbin, with mandibular tusk.

A dolbin is an animal derived from a dolphin bearing legs. Having developed in open water, the return to land has caused them to lose most of their fins.

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

IT’S TOO LATE, THEY’RE GONE

A kruleboy, the skinny, smart and conniving variety of orruk. These green, pignosed creatures live to fulfill their desire for loot, mayhem and combat, aspiring to be "the boss" of their clan.

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.

I’ll definitely be posting it relatively soon! This character is one I hope to adapt into a physical conversion from the existing plastic miniature, but that part will take more time.

At this point in time he’s pretty much going through troggoth puberty. Spending more time without an established territory has kept him mostly undifferentiated, but very much a dankhold. This will change quickly as he gets in more situations than he already has throughout his youth.

A dankhold troggoth is monstrous, vaguely humanoid beast that lurks in deep caves. Moulded by their environment, they feed on anything and everything they can get a grip on. Young dankholds develop based on the space around them, and often take on characteristics as such.
