the reason they picked that stone is because it's really heavy and good at breaking oysters or breaking nuts.

It's not going to leave or probably not going to leave stereotypical points on the rock.

And even then you could just go, well, maybe it,

you know, just got bashed up in a river or something.

Something like midden use.

It's a whole bunch of animals and birds who...

basically crap in the same spot.

They have their spot and that's where they go.

So rabbits do this, sloths do this, aardvarks, even things like wildebeest and zebra, not zebra, impala would tend to go back to the same place every day.

But the fossil record of coprolites, fossilized feces and fossilized waste from dinosaurs, it exists, but it's extremely rough.

Because, of course, this is the stuff that's already been digested and broken down.

It's already kind of gooey and broken up and doesn't have a lot going for it.

If they do it in water, it's going to dissipate instantly.

If it rains, it's probably going to fall apart.

Things like dung beetles and flies will break it down.

Even if it gets covered by sand or whatever from a sandstorm, it's probably still going to compress and separate.

So are you ever going to find it?

Maybe, going back to our trackway stuff, but even if you do, what species...

left that we know a big herbivore did this but was it triceratops or was it an ankylosaur those animals are very different things doing very different things and it would tell you different things about their behavior if we know yeah so one one piece of behavior i forgot to ask you about so t-rex engaging cannibalism yeah almost certainly well certainly i think we've got um there's a t-rex bone with a t-rex embedded tooth in it with overgrowth yeah there's i think it's

I want to say it's an Albertosaur rather than T-Rex, but there is a Tyrannosaur jaw in Alberta with a T-Rex tooth stuck in it.
