There's actually multiple times that we've found animals in sauropod footprints. The other one isn't as long of a story though. It was a sea turtle that was too slow getting off of a beach.
BAND: birds are not dinosaurs cause therapod dinosaur hands are digit 1,2 and 3 while Birds are digit 2,3 and 4 limusaurus: hold my highly reduced hand.
Limusaurus is a type of ceratosaurian called a Noasaur more specifically an Elaphrosaurine Noasaur which are shaping up to be the dinosaurs that occupied the niche many Ornithomimosaurs would later come to occupy once they had become widespread
I got so many of these ads while writing this script. I couldn't think of how to turn it into a joke that wasn't just another ad for the company though.
They really are so underrated. Especially the abelisaurs. They're best representation is the movie Dinosaur from 2000. While they show up in JW: Fallen Kingdom, they're just there to get owned by the T. rex.
@@RaptorChatter aren't the Carnotaurus in Dinosaur giants? Then again they're hanging out with Iguanadons so accuracy isn't to be expected. Ceratosaurus is the big bad (also giant compared to real life) in a Jurassic Park rip off called Age Of Dinosaurs which also has Carnotaurus in it too (this time smaller than real life if fully grown) but that film is awful.
Isn't limusaurus' digit topology considered a derived trait that evolved independently within ceratosauria? Did you reference any other sources in this video aside from the two linked in the description?
Maybe. The problem is we don't have any good hand fossils in thereopods from the middle Jurassic, and especially of basal tetanurans, so this is the next best proxy. Some developmental & genetic studies suggest the opposite of what happened in Limusaurus, so it is possible their hand development is independent. But because there's very few middle Jurassic fossils it's really hard to known how comparable the hand of Limusaurus is to other theropods.
@@BuckROCKGROIN people like this, that work _this_ hard at precision and getting it right, don't go by "common sense," they go by checklists like ones that have _•list all references in description_ on them.
There are...theropods - not "there is theropods (there's)" - and yes, I am to grammar and guitar what you are to paleontology. "There're" is the contraction. I may have spelled that wrong. I may have misspelled therapods. I am not to spelling what you are to paleontology. I'm not looking it up.
Hmm, how many times Dinosauria just trying to make avian type? I believed someday even Ornithischian would also have bird look alike type branching from Ornithopod.
So I don't get into the specifics as much because it isn't as relevant for Limusaurus, but I use ceratosaur in this to mean Ceratosauria which includes Abelisauridae, Noasauridae, and Ceratosauridae. So yes it's an abelisaur, but the abelisaurs still are members of Ceratosauria. There's also a few different phylogenies for how the 3 groups are related, but for Limusaurus it was easier to exclude the others, as it had an entirely different ecology from Abelisauridae and Ceratosauridae, which were larger carnivores.
The answer is a resounding maybe? The theropods did, and at least some ornithischians had things like feathers, so there's at least a chance. Some of these were also found in the same hole as Guanlong, which didn't have feathers preserved, but probably had them. So the conditions just weren't right for feather preservation. There's also no evidence of feathers in the ceratosaurs, including Carnotaurus, which had pretty extensive skin impressions preserved. So really we need better fossils from the group.
@@RaptorChatter a fellow not all theropods had feathers theorist I see. They might have had sparse proto feathers which are even less likely to be preserved.
@@Ginlock45 yeah I tend to hypothesize conservatively within paleontology. If there's not evidence all we can say is maybe. But I also don't get upset if they are reconstructed with feathers, because that's half of the maybe.
@@RaptorChatter t-rex reconstructions with flight feathers on the arms are always funny. As they imply that the tyrannosaurus evolved from a flying ancestor.
Um, word of advice. Perhaps slow down on your dialect and transition to a new recording tool--all of your sentences become mumbled, and it doesn't help that the acoustics drown out your voice.
@@MaryAnnNytowl If the writing is without obvious repetition I'd be fine. Again using the same phrase within a single sentence is just lazy and low effort, not to mention shows a lack of vocabulary.
