Dinosaurs became extinct 66 million years ago. Whether it was due to a meteorite impact or volcanic activity, the only fact is that they are gone forever. After centuries of study, there are still many unknowns that need to be answered about these animals. Now investigation has revealed that feathers were covering their bodies They were very similar to those found in modern birds.

If you didn’t know that dinosaurs had feathers, you might be surprised to learn that they did.. The most dangerous and famous animals of the Mesozoic had feathers like the birds we see today in our gardens. This is a recent thing, as not long ago it was thought that its skin would be rough and wrinkled like that of common reptiles. It is now known that this species had feathers.

Dinosaurs and birds are increasingly related

But what kind of feathers? Well, this is where new research based on recent findings comes in. These show that dinosaurs had feathers, yes, but their composition was very similar to the feathers that modern birds have. That is, it consists of a base of keratin proteins.

Before these in-depth analyses, researchers believed that the feathers of dinosaurs and birds were not the same. Although they were related to each other, each of them had clear differences. With the results of the past decade, it became clear that this is not the case and that the interpretations were wrong. It can now be confirmed that the two animals shared the same type of feathers.

  • Dinosaurs They had feathers Just like modern birds.
