Oh God imagine we’d actually found huge parallel footprints.
Then we’d know Jesus was carrying the t-rex the whole time

They were all made in clay-rich sandstone, which preserved the tracks so well that they have impressions of the scales on the skin of these dinosaurs.

Oooo so we know for sure what the scale shapes are? Fascinating! Where is dino science on feathers currently? Did some dinosaurs resemble birds more than lizards? Sorry I’m late. Be wild if we had such impressions of feathers somewhere

I think a lot of modern birds have scales on their feet. I googled around since I was a bit confused by that sentence when I first read it

That’s true… I didn’t know we had more than bones though. Pretty amazing that we know exactly what those scales look like.
