Discovered an ancient dinosaur group never seen

A fossil nest 190 million years ago of dinosaurs was found, with 340 leftover eggs.

According to DailyMail , the nest was unearthed in South Africa, belonging to the same breed of Massopondylus . 'It will provide clues and evidence for the evolution of complex reproductive behavior in early dinosaurs , ' the scientists said.

Interesting findings such as dinosaur footprints have led scientists to speculate that newborn dinosaurs will stay in the nest long enough to grow twice before being "realistic" . At the same time, their parents will often return to visit the team to check the situation.

The scene of the construction of the nest has just been excavated

Expert David Evans of the Royal Ontario Museum believes that there are still many fossils hiding in South Africa's Golden Gate National Park. And although science has found a lot of dinosaur fossils, information about the biological reproduction process of this giant animal, especially the early dinosaurs, is quite rare.

'We discovered not one, but a row of nesting nestles. Their date is 190 million years, so for the first time, we have a detailed view of dinosaur reproduction in their first evolutionary period , 'said Evans.

According to Professor Robert Reisz, the lead researcher, there are still many dinosaur eggs inside the fossil eggs. There are many tiny dinosaur footprints around the nest. At least 10 nests have been found, scattered in many different layers of the excavation area and each has 34 eggs arranged in a circle, pressed together.

The distribution of such a group, according to Professor Reisz's speculation, shows that dinosaurs and parents often visit the nest, and they also come to lie down and lay eggs in each group.

While mother dinosaurs are very large (6m long), their eggs are quite small (only about 6-7cm in diameter). In addition to the well-organized teams, the mother dinosaurs have a very careful mind, even calculated, arrange the nest carefully after the delivery.
