How animals were 'dinosaurs', new discovery revealed the secrets of history, debate was going on for 200 years

Were the dinosaurs ruthless with rough skin or caring for each other? Were you well behaved and intelligent? This debate started when dinosaurs were first discovered 200 years ago and this debate spread through movies.

To find answers to these questions, paleontologists usually look to their closest living relatives. In this case these are crocodiles and birds. Do we see dinosaurs as animals with complex social behaviors like modern birds, or perhaps more rudimentary habits, as seen in crocodiles and alligators?

Dinosaurs were originally thought to be ferocious, possibly cannibals. They certainly do not have the brains to take care of their children. After this, in their studies in the 1970s and 1980s, Jack Horner and his co-workers discovered the plant-eating dinosaur 'Mysora' in Montana 77 million years ago.

Horner and his co-workers found evidence that adult Mysaora dinosaurs returned to their herds year after year, indicating their ability to keep track of that location. His house on the ground was about seven meters.

In this study dinosaurs were shown to have loving parents with good social behavior and the name Mysora also means 'good reptilian mother'.

A new study by international colleagues with Diego Pol of the Egidio Ferruglio Paleontology Museum in Argentina argues that such behavior can be traced back to the origins of dinosaurs or at least the Pre-Jurassic period, 193 million years ago. .

A team at a Jurassic site in Patagonia, Argentina, studied the fossils of a dinosaur species named Mussaurus, which they believe lived at that site about 193 million years ago.

Mussaurus was a long-necked Saurapodo dinosaur. The researchers identified 80 dinosaur skeletons as well as their habitats and about 100 eggs. The shelters were shallow in the ground, in which eight to 30 circular eggs were laid in rows. The researchers used CT scans to find that some of the eggs contained small fetal bones.

The researchers measured the skeletons and counted growth rings in their bones to determine the size and age of the dinosaurs. It turned out that juvenile or child dinosaurs traveled with adult dinosaurs, and that entire herds visited their habitats each year and lived together, possibly for mutual protection and even to help the egg-laying mothers and their young. for. Such nests were found in North America, South America, Africa and China between the Jurassic and Cretaceous periods.

Can we say with certainty that this accumulation of skeletons says something about social behaviour? If you find a pile of dinosaur skeletons, it doesn't mean that they lived together. They may have come together by some river or storm.

The complex social behavior in early dinosaurs in this study coincides with other fossil evidence suggesting that dinosaurs were more like birds than crocodiles.

It may be that they had feathers from the beginning, but evidence suggests that dinosaurs and their relatives were animals that had a higher body temperature than their environment.
