Adding to the "Do Dryosaurus have quills?" question, the discovery of a feathered ornithopod in Jurassic Siberia might add the possibility that Dryosaurus do have protofeathers, or even compound feathers (the abstract told us that they're also found on the fossil, in addition to the simple protofeathers)

Question!

Is accurate to reconstruct Hypsilophodon foxii with a feathery integument?

I'd say it's reasonable. Honestly, pretty much any dinosaur is for game for feathering, more or less.

Well, except hadrosaurs and abelisaurs.

And sauropods.

But i wasn't sure about hypsilophodon. I couldn't find any reference to their integument in Wikipedia (or at least not that i can remember)

That's because no direct evidence of flesh from the genus has been found. Just because no direct evidence of feathers has been found doesn't mean it didn't have them. The equivalent would be to speculate that they didn't have skin just because no impressions are known.

Sure. Just make sure to keep feathers off the abelisaurs, hadrosaurs, and sauropods. Other than that, feel free to go wild!

list of dinosaur clades found with signs of scaly integument


More on the answer: There's nothing against restoring Hypsilophodon and other more primitive ornithopods with dinofuzz or without it so far(true feathers are questionable atm), only more advanced iguanodontians are known to possess mostly scaly (or fully scaly) bodies :)

Yup. Such melanosome fragments have also been used to determine the colour of Sinosauropteryx, Archaeopteryx, Anchiornis, and Sinornithosaurus.

Question:

I have a thinking that scorpions are the descendants of the anomalocarids, with the evolution order: Anomalocarids - Eurypterids - Brontoscorpio - Modern Scorpions. I have an opinion that anomalocarid's "arms" have been evolved into scorpion's pincers.

My question is are scorpions are descendants of anomalocarids?

Anomalocarids aren't any more closely related to scorpions than they are to any other arthropod. Even eurypterids are only distant relatives.

Has a direct ancestor of all birds been found yet?
