Prehistoric mammals are also great, much more interesting than modern mammals

All that can be found here has been royally screwed by the ice age.
There is the occasional mammoth bone find.

As well as a living fossil crustacean or something found in a lake in lappland.

Nothing cool like dinos.

>A 10-million-year-old fossil from Nebraska is thought to belong to a sandhill crane specimen but scientists are not sure if it was the very same species. However, another crane fossil dating back to 2.5 million years ago unequivocally belongs to the sandhill crane.

A very tasty nightmare. I could kill it and make arroz con polio with it.

wise choice, sir

>>73019543
Bigger Dinos probably had not as many feathers as raptors, more like a small fluff

well we had these guys

>>73020141
What makes you think that?
feathers are excellent at temperature regulation compared to mammal fur.
They can keep you cool in the desert, and warm in cold areas.

Most likely big dinos might have been completely covered with it

We'll to be honest I don't know much about feathers on dinosaurs, I agree they are excellent insulation, however during the Mesozoic the Weather was much hotter than today, almost tropical

>>73020579
So hot that there were turtles on the poles and boiling tar pits were common

watch out

Well anyway, size, or enviroment is not a factor if the dino in question had feathers or not.
There have been birds that were the size of a rhino, and had ostrich or a casoar like feather covering, and live(d) in tropical enviroments

A large dinosaur, for example, T-Rex lived in an area that had annual temperatures of 7-11celsius.
Stage 3 feathers, such as ostrich covering is actually a miracleworker of thermoregulation. While kangaroos and other mammals take shelter from the sun during the hottest hours, the ostriches stay active.

It could be assumed that all dinosaurs had them. As feathers are an ancestral trait from their distant past.
Actually, the more feathers there are, the better thermoregulation and skin protection the dino would have.

Crocs have a common ancestor with birds, where are their feathers? Too bad for swimming?

scales, scoots, reticula and feathers are all evolved from the same ancestoral skincovering.

Feathers are scales, just highly specialized.
you cant miss the "feathers" when you look at a croc

>>73021460
Interesting... what about non avian dinos such as sauropods, did they have feathers?

>>73021726
Sauropods are in the same family tree as theropods.
Saurischia.
the other family being Ornitchscia, which included Stegosauria, Ornithopoda and ankylosauria.

The split of these families happened very early on in Dinosaur evolution.

Direct evidence for feathers have been found in both distantly related Dinosauria families. And as such thinking with the terms of phylogenetics.

Yes, sauropods had feathers too.

Took a few minutes of digging.
Before the split into Ornithiscia and Saurischia, a dino existed by the name of

kulindadromeus zabaikalicus.

By the times that feathery critter lived, the split into lizard hipped and bird hipped had not yet happened.
It is even possible, that the very first proto-dinosaurs evolved from something feathered to begin with.
