How dinosaurs became the masters of the Earth and why they became extinct

(ORDO NEWS) — What allowed the dinosaurs to defeat other large amphibians, but why they were able to survive the fall of the asteroid.

Scientists have described the most ancient pterodactyl. A reconstruction of the face of the Egyptian pharaoh Ramses II was made.

Paleontology

Dinosaurs did not defeat the large amphibians that lived on Earth in the struggle for coexistence.

But during the Triassic extinction event 200 million years ago, many species of archosaurs went extinct due to global warming and left the dinosaurs with an ecological niche that dinosaurs dominated for more than 100 million years.

The main reason that made dinosaurs dominant for such a long time was climate change. It also played a major role in their extinction.

The ancestors of dinosaurs are approximately 235 million years ago. Reconstruction

Scientists have provided new evidence that dinosaurs felt very good before the asteroid fell and were not going to die out.

Scientists reconstructed food webs over several million years before and after the asteroid impact and showed how some mammals and birds survived the catastrophe that ended 165 million years of dinosaur life.

Dinosaurs were too well adapted and did not have time to change to adapt to new conditions. And mammals were small outcasts, they ate everything they could. And so they were better prepared for change.

An almost perfectly preserved pterodactyl that lived 152 million years ago

Paleontologists have described the oldest specimen of pterodactyl. He is 152 million years old. It was discovered in 2014 in a limestone quarry near Peinten, a small town in the mountains of central Bavaria.

It took several years of very fine and careful work to extract the skeleton from a piece of stone. The skeleton of a small pterodactyl is almost perfectly preserved.

He is about 15 cm. But this is a sexually mature, adult pterodactyl. The kings of heaven were also small.

Painting in the Green Room

Scientists at Cambridge University have examined an ancient Egyptian masterpiece that is over 3,000 years old.

The picture, which adorned the wall of the palace, which belonged to the daughter of Akhenatoth and Nefertiti, depicts birds that lived in the Egyptian swamps in a completely realistic way.

Scientists have identified them. The painting realistically depicts shrikes, wagtails, kingfishers and pigeons.

British scientists, together with colleagues from Egypt , have created the first scientific reconstruction of the face of Pharaoh Ramesses II, who died 3,200 years ago.

The reconstruction shows the face of the pharaoh right before his death – at about 90 years old. Here’s what he looked like when he was old:
