Moby, a large Leucistic Tyrannosaurus rex features front and center. Associated quote from Skinner Abelard, the operator of the cloning facility that produced him: “Biggest one yet son! This little chick is three times the size of our standard stock!”
A graphic showing naked giant ground sloths versus a sparse coat versus a thick coat according to regional environments
A mournfang, ogor-ridden beasts that thrive in cold environments. They are hoofed predators with long tusks and powerful jaws. Like a bison mixed with a bear, they feature traits of carnivorans and ungulates, almost a throwback to extinct mammals.
A cartoon Compsognathus in expressive, piebald pigeon colors. To its left stands a previous, lower opacity sketch from which it was refined.
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.
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.
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.
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.
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.
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.
Hadrosaurus foulkii is the state dinosaur of New Jersey, an elephant sized herbivore from the end of the Cretaceous
An assortment of red, bouncy squigs. These rubbery miscreants are somewhat grotesque in appearance, faces appearing somewhat humanoid in expression and feature. Closely related to orcs, they are a sort of fungus in reality.
Daeodon, a relative of hippos and other even toed ungulates, shown here with a mane and wisped knobs on its snout. This pig-like animal was large and dangerous.
A snotling and a Gnoblar, two types of goblin, walk along merrily, the snotling confidently brandishing a mushroom. The gnoblar carries his gear and snacks for the road.
A Styracosaurus in dazzling sunlight
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.
The Dinochicken is a recombined mutant of both dinosaur and chicken DNA. This half baked creature has some traits from all three of its biological origins: A cassowary, a featherless chicken and struthiomimus.
A hazmat-suited figure observes a creature within some sort of nutrient bath
A graphic showing morphological differences between extinct proboscideans from the end of the Pleistocene.
The common garden gnome. A three digited, monkey-like sapient creature.
The lying baboon was named on appearance. It was horribly incorrect once genetic data was able to be decoded.
The bullytrog pictured is less than a meter in height, and horribly brachycephalic. Like a pug or inbred bully-dog, they suffer to function.
A walrus-like trog, the waldur is a deep-sea diving, green creature
Bark’s greater trundler, the largest species of troglodoid. Elephantine but walking on their wrists, the beasts little resemble their bipedal origin.
A size comparison of a stilt-legged raksha. A large troglodoid with two digits on each appendage. Mostly hairless, their tails have a plume of long follicles. These beasts stand at almost 4 meters high.
Size comparison of the humped desert goggerbairn, a troglodoid of lumpy shape with two humps. Long tusks protrude from their jaw, large ears funnel heat, and they bear long and gangly arms.
Another Fracas F, inlaid with a particularly atrocious mug…
The classic Fracas F, inset with something very large…
A teaser image placing a mysterious creature within the eye of the Fracas…
The gryph hound plush next to its coloring page!
A swamp troll bearing fishy characteristics. You are what you eat, and the blue and yellow color of the skin is derived from brilliant fishes that make up the majority of a troll’s diet. Its jagged, exposed teeth are additionally perfect for crunching through prey.
Battle for skull pass goblin shaman front view
A metal orc raider painted in festive colors! His candy cane torch burns with the sweet aroma of peppermint.
A sketch of a troll, based on primates including macaques, this creature has a bulbous nose, clefted tusks, and pig-like ears. The woodsman troll is a browsing herbivore that primarily feeds on pinecones, berries and woody browse. They will often knock smaller trees down, and keep forests from becoming too competitive.
A calendar image showing the prompts of Trollvember to be completed at any pace.
Smilodon, a large saber toothed cat, reconstructed here with fleshy jowls that cover its nearly foot long fangs. The likelyhood of this reconstruction is in doubt.
JÖRMUNGANDR
Squigs! Dimwitted red bipeds with short tails and massive mouths.
An open eye surrounded by nutrient providing organs and tubes looks back at a suited researcher from its cloning vat. The researcher makes note of this on their tablet.
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.
An orc inspired by frogs. Their young hatch from eggs, and slowly develop arms and legs as they age.
Dolbins are much like dolphins, but retain their hind limbs to some degree. They are alternative evolutionary forms sprinkled with a dash of fantasy.
4 beer cans illustrated with dinosaurs, proudly displayed on my parent’s shelf.
Three swamp trolls. Scaly, slimy and made with hints of fish.
An alpha troll cutout made from with ink and watercolor. He is armed with a rock mounted in a tree trunk, and is scarred from a lightning attack across his upper body.
A lone swarmlord faces off against 4 chaos knight wardog titans after mulching one.
Tyrannosaurus (hybrid genetics)
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.
6 mastodon models colored from various mammal inspirations. Of note are the Malayan tapirs’s white and black stripe pattern, a grizzly dark brown hood, and a piebald splotchy creme and tan.
The common warg. A large fantasy creature around the size of a lion that bears a badger/dog like appearance. They cohabitate with goblins.
A sketch of the pig-like “gore grunta” lacking the gore. These beasts are rounded up and goaded into battle by Orruks, who care little for their well-being.
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.
Three Eremotherium browse and rest among the trees of what would be Georgia, North America. These sloths are the size of elephants, and may have had significantly more hair.
