And that's going exactly back to, again, that stuff we were talking about, bite marks and toponomy and the history of specimens and how you interpret them.

So it's really, really tough.

So the main one which was put forward is there's this famous association in Montana of Deinonychus, which is often confused with Velociraptor, including in the books and movie, basically a bigger version of this that's rather older from the early Cretaceous.

And a thing called Tenontosaurus, which is kind of Iguanodontin, so Iguanodon with the spiky thumbs.

basically otherwise a fairly run-of-the-mill herbivore.

And there are two sites, I believe, for this, but there's one that's much more important where you have a Tenontosaurus carcass with Deinonychus carcasses.

And so the interpretation of this is, well, this is a group that brought down the herbivore.

And of course, the immediate kind of counter-argument to that is,

well, why did they all die there?

Like when, you know, when lions kill a wildebeest, they eat it.

They don't all just die next to it.

Yeah.

Or even if they did kill it and start eating it.

And then like, if they got into a fight and killed each other, well, lions as a species are not going to hang around for very long.

If every time they kill something, they get into a mortal fight and kill half the pride.

Um,

There's nothing obvious that killed them, but it's at least possible that this was something like a predator trap.

So predator traps are really neat.

So the La Brea Tar Pits is a classic example.

The idea is a herbivore stumbles into something like tar.
