I saw the list from @a-dinosaur-a-day today and liked it. (I also miss inktober).

Here’s a proud Patagonykus. Really fan of Alvarezsauridae.

(( I hope it’s accurate enough.))

The Science of ARK: Utahraptor

Dromaeosaurs (‘running lizards’), popularly known as raptors, were a group of predatory theropod dinosaurs that bore distinctive, curved ‘sickle’ claws on the second toe of each foot. The exact function of the claw is unknown, and may have varied depending on the species. Theories include uses for slashing prey, climbing trees (or other animals) and restraining prey underfoot. These dinosaurs were definitely feathered; fossils with preserved soft tissues all show advanced types of feathers, and marks on the arm bones of Velociraptor and the larger Dakotaraptor preserve attachment points for wing feathers. The use of these feathers varied by species; small raptors like Microraptor could use them for gliding, while large species may have used them for display or rapid flapping to assist in pinning down prey, as modern secretary birds do today.

Estimated to reach 7m (23ft) in length, Utahraptor is the largest known dromaeosaur. It is known from fragmentary remains discovered in Utah, USA (hence the name, meaning ‘thief from Utah’). Its life appearance has therefore been largely speculative, though as new material has come to light, Utahraptor has been revealed as a more robust and muscular animal than other dromaeosaurs (see here for an updated skeletal image). A recent remarkable discovery has been of a family of Utahraptor, in different stages of life, preserved in a single block; you can donate to fund the preparation of these amazing fossils here.

In ARK

While dromaeosaurs had been a minor component of prehistoric pop culture since their discovery, it was the villainous raptors of Jurassic Park that propelled the group to international infamy. Though the film did help to popularize new theories about dinosaurs, it’s also paradoxically preserved its stars in something of a time warp, with many depictions of dinosaurs based on the Jurassic Park versions. Evidence that dinosaurs, particularly raptors and tyrannosaurs, were feathered is often greeted online with detractors saying that they ‘don’t look cool anymore’. I beg to differ.

This goes some way towards explaining why the ARK’s Utahraptor resemble the Jurassic Park models with plumes of feathers sprouting from their heads, necks and tails. In reality, even the largest raptors would be feathered head to tail, resembling toothy birds rather than the lizardy creatures from 1993. Additionally, we now know that Utahraptor was a stocky, robust animal built for power over speed, whereas the ARK raptor is a slim, speedy creature.
