It often amazes me how much our knowledge of dinosaurs has changed since I was a kid. When I was born, the idea that dinosaurs were warm-blooded, often feathered, and evolved into birds wasn't generally accepted. These days, it's practically a mundane fact.
Yup. With their pea sized brains. Walked all slow could barely hold up there own weight. etc, etc, etc..

I would be interested in knowing how they determined the feathers were not from birds.
Probably from accounts left by people who had dinosaurs as pets. Maybe that museum in Kentucky has something.

By the way, the feathers in that article date to the late cretaceous period, when birds already existed. I would be interested in knowing how they determined the feathers were not from birds.

That's a good question. There was a temporary exhibit at our science center featuring feathered dinosaurs that I worked at, and it was theorized that the feathers belonging to dinosaurs were more hair-like rather than like the feathers we know of today, and moreso for warmth, that therefore they couldn't belong to birds since they weren't built for flight.

I have an Uncle who's a paleontologist who's actually been to Liaoning in China where it was first discovered, so I'll try to ask him to get more of a definite answer.

Re: Images of dinosaur feathers in amber

As I understand it, that refers to the earlier feathers as opposed to the feathers that existed by that point (in other words, the early evolution of feathers were more hair-like).

Of course, there's a fine line (if one at all) between Dinosaur and Bird.

How big were the "birds" in that time period? Is it possible it's just the size of the feather that's a clue.

Yeah, that makes sense. I'll still have to ask my Uncle for something more precise as per the actual question. I also think the hair was also more dense, so it protected them too. So, it's not so much that Dinosaurs were like birds, but that dinosaurs did have elements that were bird-like.

There was one dinosaur in that exhibit that looked like a giant ostrich more or less, and rather quite tall.

One thing about dinosaurs that I've just recently realized is that not all of them lived at same time. For example stegosaurus and tyrannosaurus had ~100 million years between them!

Re: Images of dinosaur feathers in amber

Yeah, dinosaurs were not all contemporary to one another. They emerged about 230 million years ago and most were extinct by 66 million years ago. That's over 150 million years in which to see many species rise, fall, diverge, etc.

For comparison, the first homo genus appeared less than 3 million years ago, and we've identified at least 12 species in that genus which predate modern humans. There are likely numerous species of dinosaurs--perhaps many tens of thousands--we'll never even know about because no fossils survived.

To think that when Tyrannosaurus was stalking the Earth, Stegosaurus had already been extinct longer than Tyrannosaurus now has!

Yep, that's why they're all divided into different periods of existence.

Yeah, but even then, the sheer size of the numbers makes it hard to comprehend.
