Could Triceratops really have had quills or feathers? How did this theory originate? Houston Museum of Science paleo lab manager, Colin Diggins, explains Triceratops quill theory and more while standing in front of the most complete Triceratops and best preserved Triceratops skin impressions ever found. www.hmns.org/

What do you think? Have any questions about Triceratops or anything else in paleontology? Let us know in the comments! We'd love to feature future videos based on your questions! :)

Could you make a video about the stegosaurus and allosaurus and how there’s stegosaurus thagamizer impressions in the allosaurus’s pubic bone? And talk about how the stegosaurus aimed said thagamizer?

I like this explanation and communication a lot more than the last few videos on the same subject. This person communicated the science clearly. He established and defined the theory/hypothesis and clarified its level of possibility, rather than talking in absolutes. "Triceratops *may* have had quills" is a lot more honest and better than "Triceratops *did* have quills". A big and important difference, especially in Science communication. Nice video.

What's amazing is how dumb most Paleontologists get to finding the obvious answers.

0:14 That's actually John Conway's Triceratops from All Yesterdays. I would not be surprised if Triceratops and other ceratopsids had a sparse covering of filaments left over from their ancestors that didn't serve a mechanical function. Kinda like elephant hair.

Your elephant hair analogy is precisely my personal theory. I don't think it's far fetched at all. Many large modern animals have very thick hair follicles. - Johnny

I always have been to your museum so many time I love it so much but when is saw the skin I had seen the holes and I hat thought that it had quills

Wow that is very interesting. I don't know but the evidence seems to lean in that direction.

That's why I love Colin's explanation. He explains exactly where the theory comes from, but that it certainly isn't the only theory.

In what direction? The quill/feather idea or the highly ornamented scale idea?

Oh sorry, the quill idea.

@@andrewshear2927 what makes you think the quill idea is more likely to you than the ornamented scale idea? The guy in the video didn't really explain the likelihood of it in detail.

Except beetles do tend to burrow in things like bone or a carcass--much would those burrows be organized. So, how are we positive these depressions don't belong to an insect?

@william3100 3 күн бұрын

Probably because the animals skin was lying down flat on the ground when it died. The beetles would have to burrow up through the dirt with the skin pressing down on it or dig through the other side to get to those points, which doesn't make any sense to me. I think those beetles burrow into animal skin on the top where it's much easier to form organized spaces between them instead of underneath.

@@william3100 Not necessarily. Most, if not, some species of beetle would prefer brooding their eggs in a carcass, providing the incubating larva the nutrients contained from the animal it'll later consume.

@@TheMightyN but then the larvae, when grown enough, will come out from the top side rather than on the ground-facing side of the carcass into the ground. Those beetles implement the eggs into the carcass from the top-facing side I presume? That would mean that the holes go inward rather than outward like the fossils. Edit: they also only do that for small animals like small birds and rodents. Not to megafauna like triceratops. That's because they have cover the carcass in inches of dirt before rolling them into a ball, then lay the eggs in. I just found out about that. Unless you're assuming giant man-sized beetles existed back then, I don't see that happening.
