Dinofact #43
Dilong paradoxus is a basal tyrannosauroid from China. Fossilised skin impressions from the animal near the jaw and tail show that it was likely covered of simple feathers. The simple structure of the feathers could not have allowed for flight, so it is likely that they were used for insulation. Adult tyrannosaurs found in Alberta and Mongolia showed skin impressions of the typical pebbly scales, leading paleontologist Xu Xing and colleagues (who also discovered Dilong in 2004) to believe that the dinosaur may have had feathered in some spots but not others. Additional speculation is that juvenile Dilong had a coat of insulating feathers, but these were lost in adulthood because the adult dinosaur no longer needed the additional insulation.

My female carnotaurus character Calliope heading down to the beach for a swim. My old computer finally gave up the ghost after 10 years of okay service so this is the first painting of my new computer.

Tell us more about dinosaur scales? 👀 Saw the misconceptions post mentioning how dino scales were super weird actually and now I'm curious what kinds of things were up with them!
so the important thing to remember here is that the evidence indicates the ancestral dinosaur was a fluffball. it seems as though, based on this evidence, that different groups of large dinosaurs evolved scaly body covering separately to deal with the problem of being bigger and thus overheated by protofeathers (or regular feathers. I don't want to get into that atm). so that means that different forms of scaly covering evolved in dinosaurs many, many times (it's unclear how many times)
so the weird thing about dinosaur "scales" (technically they're scutes, not scales, but I'll just say scales for sanity reasons) is just how not uniform they are. yes, lizard scales vary a lot, but they generally follow similar rules. dinosaur scales have no rules.
these are the scales on the back of the head of edmontosaurus, a hadrosaur. they're small, usually. they don't overlap. they are vaguely octagon shaped. sometimes there are bigger scales instead.
these are the scales of a sauropod. notice how they are way more variable in size and shape, with some having five ish sides and some having six ish sides. they still don't overlap. they don't tesselate quite as well as hadrosaur scales, and just seem to fill in as much space as possible. they're also bumpier.
here. have the sheer variety of scale designs in different Saurischians, the group that just kept evolving newly-megafaunal clades over and over again.
and they weren't all small! here are the scales (and SPIKES) of triceratops. notice their much larger size.
stegosaurs/ankylosaurs, ceratopsians, large ornithopods, sauropods, ceratosaurs, megalosaurs, allosauroids, and tyrannosaurs all evolved to be big from small fluffy ancestors independently, and they all did it in a different way. and sometimes they just messed around with that way for fun.
the diversity of dinosaur feathers is equally matched by the diversity of dinosaur scutes (scales).
