Bistahieversor sealeyi


Temporal range: Late Cretaceous, Campanian, around ~75 Ma

Length: Around ~9 metres
Probable mass: Around ~2-3 tonnes

Etymology: Sealey's Bistahi destroyer


Bistahieversor is a genus of tyrannosauroid dinosaur, that lived around 75 Mya during the Late Cretaceous. Material from adolescent and adult Bistahieversor individuals has been found in the Kirtland Formation of New Mexico, United States.

The snout is deep, an indication that the feature is not unique to more derived tyrannosaurs such as Tyrannosaurus. Geographical barriers such as the newly forming Rocky Mountains may have isolated Bistahieversor from the more derived northern tyrannosaurs.

Bistahieversor is highly distinguished from other tyrannosaurs by the possession of 64 teeth, an extra opening above the eye, and a keel along the lower jaw. The opening above the eye is thought to have accommodated an air sac that would have lightened the skull. Bistahieversor had a complex joint at its "forehead" that would have prevented movement at the joint, stabilising the skull.

gorgeous drawing! just a question, i thought carnivorous dinosaurs couldn't produce any cool pigments like blue or green, am i mistaken? :P

Their feathers couldn't produce blue or green. Their scales and/or naked skin could have blues and greens though.

That really looks like a blueprint for T. rex...

Nice work. I like the look of the feathers especially!

Yeah! Tyrannosaurids with feathers! Looks way cooler, than the unfeathered ugly reconstructions, by others!

I agree completely, feathered tyrannosaurs >>>>>>>>>>>>>>>>>>>>>>>>>>>>> unfeathered tyrannosaurs in coolness, aesthetics, and scientific accuracy :)

At least we can all agree that the earliest reconstructions...

...let's not talk about those ones...

Seriously, anyone who thinks dinosaurs never had feathers needs to study hard and at least accept truth. I honestly think it would be AMAZING to see that Bistahieversor in real life, covered in adorable fluffy feathers and acting like an animal should, while looking majestically FABULOUS at the same time. It would be PHENOMENAL to see something like that.

Oh btw; +fav
