Planet dinosaur

[@voodoodudu2547]

Sometimes they can tell what a creature ate because they find other fossils that have teeth marks in the bones that match that of a predator. They have a lot of experts like dental experts that can tell a lot from tooth fossils alone. It has someone else said there are fossils that have left skin imprints, there are some fossils that have even left pigmentation cells so scientists can figure out what color they think it was. I'm pretty sure there was at least one feather dinosaur that left pigmentation cells so scientists could figure out what color it's feathers were.

[@A.Mortem]

The thing I've recently learned about extinctions is that as long as some animals are left they will fill the roles of the animals no longer there. Obviously we won't see them evolve into new and exciting animals but it will happen.

[@AshrafAnam]

I thought lions and tigers were considered majestic

[@ansh6370]

What's the point? Every species has to go extinct one day. Just let nature go as it is going.

[@bkjeong4302]

A. Mortem Actually if things are bad enough this won’t happen. Humans are basically making it impossible for large animals to evolve for a few million years.

[@FalconFastest123]

We already do protect other species and have helped numerous species come back from the brink of extinction. Human population is expected to peak at about 10 Billion and then stabilize at that number. We will not be the end of life as so many alarmists have claimed.

The problem is, that humans have already discovered most of the surface waters and marine reptiles like the mosasaurs, didn't had gills, they had to come to surface for breathing. So even if there is a marine reptile bigger than the mosasaurus, it would be easy to spot it.
