The oldest dinosaur nest found in South Africa


25/01/2012

Nest of dinosaurs that were recently discovered in South Africa were 100 million years older than the ones that were open earlier scholars. Paleontologists have found 10 freestanding slots, each of which contained up to 34 eggs measuring 6-7santimetrov. Fossils belong prozavropodu masospondila (Massospondylus), who was a relative of such long-necked sauropods such as diplodokus (Diplodocus).

Scientists suggest that masospondily neodnakratno returned to the nesting, laying eggs in groups - the oldest example of "colonial nesting".

The remains of antiquity 190 million years old, among whom were the skeletons of dinosaur embryos have been described by paleontologists in the journal Proceedings of the National Academy of Sciences. Ancient fossils have been found in the Golden Gate National Park in South Africa.

The researchers noted that the rock there are still plenty of places that will soon be available due to the destruction of the natural process of rock under the influence of the atmosphere. But the recent discovery has brought much more information about the dinosaurs that lived on Earth in the earliest stages of life.

"Despite the fact that the world has recorded quite a few sightings of fossil dinosaur variety of species, we are actually very little information about their reproductive biology, particularly the earliest periods of the dinosaurs" - said David Evans (David Evans), head of paleontology at Royal Ontario Museum.

"This amazing series of nests age of 190 million years will allow us to learn more about dinosaurs playing early in their evolutionary history, and serves as proof that breeding was characteristic of the early period of the dinosaurs." The researchers are now engaged in careful extraction of eggs preserved embryos that will help them to further explore the various stages of the development of the dinosaurs. "

Besides embryos scientists also have found traces of fossilized dinosaur young. This may indicate that the nests were not just a place to lay eggs, but a kind of kindergarten. According to the scientists, the dinosaurs likely remain in them as long until they reached a certain age.

New Record broke the previous record of paleontological, then, in 2011, researchers discovered in Mongolia’s nest, in which there were 15 young dinosaurs.
