Like, these are weird and rare outcomes.

These don't usually happen.

The vast majority of active predation is on stuff much, much, much smaller than you.

I totted some of this up for a paper I did on Microraptor, this really small gliding dinosaur from China where we actually have a bunch of specimens with various stomach contents in them.

And we were coming up with numbers of about like five to 20% of the mass being typical.

So prey versus predator.

And that's actually very similar to what we see with modern carnivores.

And it's not far off what we've seen, even with things like tyrannosaurs, where you occasionally find consumed bones from prey.

So if we put the lower end of that as 5% of the mass of a T-Rex, we might actually be okay if it doesn't consider us worth the hassle.

then assuming you're encountering a big adult and not a half-sized one that maybe only weighs a ton, then we might be all right.

not moving yeah it's nonsense they can see really well like i said like t-rex has giant eyeballs people don't realize that because like whales and like elephants it looks small compared to the size of the animal but what you're in really important for vision is absolute size not proportional size and absolutely their eyes are gigantic

Probably the biggest on Earth at that time.

Yeah.

A guy called Kent Stevens did a paper.

He's got a really nice graphic of it.

If you just put S-T-E-V-E-N-S, T-Rex.

There's the one with the googly eyes.

That's a baseball or a tennis ball sized eyeball.

And when you think about the incredible visual acuity of something like an eagle, which has eyes not much bigger than ours,

Think about what that's going to do.
