We do have fossils showing aggressive interaction between the two. If chewed bones weren't enough, there's a Trike who got its horn bitten off and survived. |

Well, while we do have evidence to support it, it probably started with scientists thinking: "Oh look, a huge carnivore. Oh look, a huge herbivore. They lived in the same environment. Probably fought a lot." Cue Charles R. Knight's painting. Lucky for them, they got the obvious right. |

Was it likely for early, primitive tethanurans (Chilesaurus, Cryolophosaurus, Monolophosaurus) to have some kind of feathers? I've seen many restorations of Chilesaurus featuring filamentous feathers so far, and I think Cryolophosaurus probably had some kind of covering because of its polar habitat, but are fossil findings that support these reconstructions? Greetings! |

This really depends on who you ask. See, I lean towards a "no" on this one given that the clades on either side of the group of animals you refer to are known from scaly remains, the allosauroids and ceratosaurs. Allosauroid skin is known from very fragmented impressions from a juvenile allosaurus and a pretty reasonable portion of Concavenator, which combined suggest the "typical" small, mosaic type scales most commonly associated with dinosaurs, with more rectangular shaped scales on their belly and underside of the tail. Ceratosaur skin is known from Ceratosaurus's dorsal scutes, and the only Carnotaurus specimen we have, which suggests very thick, wrinkled scaly skin with irregular rows of osteoderms along its body (granted, Carnotaurus was the most derived member of the Abelisauroids, and indeed of all ceratosaurs, so we cannot say for sure whether this kind of integument was common to all ceratosaur). Unfortunately, nothing is known from spinosauroid integument. We thought we had something for a fluffy baby megalosaurid but nah, it turned out to be a "compsognathid". On that basis I'd tell you that it was unlikely that anything that sat between ceratosaurs and allosauroids was feathered and that you should put small (like, very small) hexagonal scales on it. Of course, someone else at this point would leap in and talk about how the presence of fluffy ornithischians probably makes the ancestral dinosauromorph feathered and that fuzzy integument was the norm and not the exception. I personally disagree with this statement but its a reasonable hypothesis regardless. Just, whatever you do, don't restore Chilesaurus with a god damn beak. People are constantly doing that and it is blatantly WRONG. |

Wait, 52 !? Last time I checked the longest estimate I found was 40

How flexible was the neck of Brachiosaurus and other similarly shaped sauropods, like Sauroposeidon and Giraffatitan? I keep thinking about how they were able to drink, but I'm unsure if these tall sauropods were able to bend their necks low enough to drink. |
