So much keeps getting discovered about dinosaurs! If you want to catch up on the last 20 years of research, particularly on the feathered front, I recommend this book: https://www.goodreads.com/book/show/23394100-flying-dinosaur...

(As the mum of a 5 yr old and 3 yr old, I feel obligated to become an expert on all things dinosaur.)

Ok I'm confused, I thought consensus nowadays was that dinosaurs had feathers, yet the impressions here are both leathery? What's our current best guess? Also, what animal has a leathery covering like that, rather than scales or supple skin?

I have a pet theory that most "new" dinosaurs being discovered are just dinosaurs we already know about at different stages of life.

My theory keeps getting stronger: the trex was a crawler, and did not stand majority of the time. It ate small stuff on the ground like an iguana.

That second artist impression is pretty nice. I wonder what non-avian dinosaur plumage felt like.
