how can scientists say how dinosaurs behaved and what they ate(what they ate is probably a bit easier). we only found skeletons and sometimes whole stoned pieces and there are so many films and documentaries with or about dinosaurs. if im not mistaken then was a trex not able to go faster as 4km/h because if it wanted to go faster it had to have 80%of its musclemass in its legs and that should be impossible(from physics and mechanical engineers and bionical engineers said)?? enlight me pls :)
Primitive mammals (know as reptile-like mammals) lived before the dinosaurs and got to large sizes during the Permian era; the Gorgonops is a representative. But another extinction event at the end of the Permian cleared the playing field and this time the dinosaurs were quick off the mark. Mammals grew small and bided their time.
I've seen another vid, in which evidence is brought forth to support the hypothesis that the lung structure of therapsids (mammals and ancestors) proved unsuited for supporting larger physical dimensions during the oxigen-low Mesozoic, whereas this change in atmosphere did not pose a burden on the more efficient lungs of sauropsids (dinosaurs, birds and present reptiles), who grew on to dominate that era.
That was so educational. I'd no idea mammals and dinosaurs used to live with each other for millions of years. I used to think that mammals started appearing on earth once dinosaurs were disappearing.
It kinda made me feel smart, because I was going to say before the guy in the video, yea there were mammals in that time, just extremely tiny. They were more pronounced I believe after the extinction of dino's.
Most things are relatively dated. There is no way to determine EXACT age really. Everything has a pretty huge error. So the age they tell you may have an error of +- 5 millions years. Which explains the discrepancy of the two times.
In geologic time, a couple of million years is not really anything.
@N00bcrunch3r We dont actually know when dinosaurs first appeared, and I dont believe there was any "last dinosaurs", I believe all dinosaurs lived until today.
@N00bcrunch3r Ignorance, ignorance, ignorance! You stupid people must be totally stupid because you always seems to be obsessed with "ignorance", if there are anyone here on Earth thats ignoring then thats you and a few other fooled ones around the world. Thats clearly obvious! Me and many others are clearly NOT ignoring anything. You maybe dont even know what ignore means.
@N00bcrunch3r Oh, you knew what ignore means, congratulations! We will not have a "SCIENTIFIC" debate, more a truth-debate or something. Unprofessional, yeah thats you! No doubts. I´m sure you can´t even provide any reliable and REAL proof.
no but their anatomy and appearence was similar to rodents, but some were distantly related to us. in this case, purgatorius is one of the first proto-primates, the ancestors of the primates.
Aww, Purgatorius are so cute <3 I'd adopt one if they weren't extinct D:

Well, the first dinosaurs appeared 228 million years ago, while the last dinosaurs dissapeared 65 million years ago.

You may not, but scientists have found that the earliest dinosaurs date from the middle Triassic with the likes of Eoraptor and Thecodontosaurus.

Yea, if Mammals were any bigger Dinosaurs would've driven them to extinction. The small size made it easier for them to hide.

No, the smaller ones would have survived and still become rodents.

@Chimera1591 but one kind was as big as a bulldog and ate dinosaur babies, google Rapenomamus.

It could also eat full grown dinosaurs like Caudipteryx, Sinorthosaurus, Mei, and Microraptor.
