That's probably the case, even if Denversaurus didn't evolve directly from Edmontonia then it at least derived from an extremely similar nodosaur that would've shared a very recent common ancestor with Edmontonia.

Denverasurus is about as close to Edmontonia as it is to Panoplasaurus. It is more likely that they were transitional forms between all of them but the scrapiness of the fossil record meant that we hadn't found them, at least yet.

https://en.wikipedia.org/wiki/Velociraptorinae

''several indeterminate velociraptorines have also been discovered, dating to the Kimmeridgian stage, in the Late Jurassic Period. These fossils were discovered in the Langenberg quarry, Oker near Goslar, Germany''

oh My, what does this mean?

It means velociraptorines are a bit older than we thought, I don't see what the big deal is.

They're also apparently just known from teeth so the classification seems tentative IMO.

I thought Deinonychosaurs as a whole were an exclusively cretaceous clade.

Not at all, there are deinonychosaur teeth dating from as far back as the middle Jurassic, and possibly even full-body fossils depending on whether or not you consider Anchiornis and Archaeopteryx deinonychosaurs (which IMO is the preferable classification).

IIRC there are large Velociraptorinae remains on the Isle of Wright (if I spelled that right).

Do we have any evidence of predation by Torvosaurus on other animals ?

I feel like you guys are forgetting about Pedopenna, but of course I could be misguided.

Yes there are remains there and that would explain the use of Utahraptor in Europe in WWD seeing as how the dromaeosaur found Wasn't described so they had to use the next best thing. However that's a topic for a different discussion.

I would like to say yes but I'm not sure...IIRC there are associated bones of Stegosaurs and I think a sauropod femur that shows Torvosaurus teeth marks but I'm not sure if that was even a reliable paper seeing as the site I found it on no longer exsists and it was back in 2009 when I found it

so that means that Dromaeosaurs like Velociraptor and Acheroraptor were around during the late Jurassic period?

Not them, specifically, no.

What I meant was close relatives that looked like Them in appearance

Potentially. It's entirely likely that such features could be observed in more basal deinonychosaurs and that it was only at the turn of the Cretaceous that they radiated.

So when ever done sees Pteranodon the first thought is "Pterodactyl" now we have a species called Pterodactylus. If someone really wanted to could they name a pterosaur Pterodactyl or is the name technically already used?

what would happen if the Cretaceous/Paleocene mass extinction event had the same effect that the Triassic/Jurassic mass extinction event had? what animals would still go extinct and what animals would survive?
