Meh, doesn't present much behind this assumption. For the record, the frill lengths don't follow much the pattern of frill growth among the ceratopsids, with the most juvenile form having proportionally not much shorter frill than the supposed adult form.

Two questions actually the first were all t-rex feathered or could it depend on habitat and weather. Lastly do you think the cave lions acted like modern african lions in terms of behavior.

they were most definately feathered, only the amount of cover would change depending on the location.
and for the lions, I'm not sure we have proof of their behaviours.

There's nothing to suggest that one or the other T.rex was more or less feathered, the same old "but elephants are bald" doesn't apply here. The only variation I could suspect is the amount of feathers on the face/neck.

Well, all that was found of Brachyceratops were juveniles, there were rumors that it was the juvenile of Rubeosaurus

Did a jurassic theropod like Allosaurus have any form of feathers ???

We still don't know, so it's up for speculation. I like to think that all Theropods somehow were feathered, but I'm quite biaised towards the subject.

There's confirmation of scaly integument in the genus Allosaurus, but I failed at finding credible sources on the size and location of said skin imprint/fossil. "Safe" pick is that Allosaurus was scaly. A bit speculative is that it could have had some form of primitive dinofuzz, but it's in the end just speculation. :P

Well say for example a herd of brachiosaurus is walking trough a plain area in a severe storm, would it then be realistic for the dinosaurs to be struck by lighting ???

That would be a serious problem for sauropods.

Just as much as it is now today possible for Giraffes :)

Had Dryosaurus quills ???

Would a kaprosuchus be able to break trough a wooden enclosurefence ???

I was wondering, is there any possibility dimetrodon had at least a thin hump?

I don't recall any evidence of any type of integument in Dryosaurus genus. Gregory Paul restored it with dinofuzz for example, but it has no solid basis so far.

Depends on what Kaprosuchus looked like in real life. If it was indeed a 6m long animal, then it depends on the thickness of the wood. I'd say anything capable of stopping a charging bull would also stop this animal :P

If at all, it could (and should) have some thicker flesh on the base of the sail - enough to cover the normal amount of vertebrae found in other sphenacodontids. But in general, the structure found on Dimetrodon's back was a sail. Not a thin, carved-to-bone hump like many depict their malnourished spinosaurids, but a literal skinflap sail.
