So here this is being explored by this vidoe - and I kind of chuckled

There Are Way More Dinosaurs Than You Think
This doesn't even cross my mind. There is over 10,000 species of birds
now... and almost none would survive fossilization events. And there is
only a few thousand species, tops, of know Dinosaurs. It doesn't even
scale. There is likely almost 150 million species of Dinosaurs over
that long period from the Triassic to the Cretaceous.
The idea that we even have a reasonable idea of how life was even at the
KT boundary I find hard to believe. It is amazing how much we know.
Animals constantly do astonishing things we would never expect just from skeleton structures.... Even a species we know fairly well, like a
T-Rex.. I doubt we know nearly anything of their abilities or functions.
