Paleontologist dinosaur embryo fossils of the oldest recognized

Paleontologists confirmed that so far the oldest known dinosaur embryo fossils are about 1.9 billion years ago, living in the vertebral giant dragon.

These include a complete embryo vertebral giant dragon egg is found in South Africa in 1976.

In "Vertebrate Paleontology" magazine published a research report also provides information on the case of the early development of dinosaurs.

Paleontologists have recovered fossils of these embryos is also under a giant dragon just hatched when the vertebral image.

Sauropod animal ancestors


Vertebral giant dragon in the embryonic period of about 20 cm long, but the adult up to 5 meters.

University of Toronto researchers believe that these dinosaur egg fossils discovered so far in all the land of the oldest vertebrate embryos.

Four-foot long giant dragon neck vertebrae, great size, is the original small jaw dragon is the ancestor of sauropods.

The researchers found that a small dinosaur embryos in the 20 cm in length, are mature enough to be hatched level.

However, infants and young children during the giant vertebral vertebral giant dragon with an adult dragon looks different, before the legs, is likely to be four-legged walking rather than as an adult as a giant vertebral Long walks on two legs.

Their head is relatively large. Adult giant vertebral body length 5 meters long, long neck, small head.

With age, vertebral giant dragon cub physical change.

Study reported that the structure seems to indicate that the fossil embryos, giant vertebral parents need to feed a baby dragon, it would be difficult to survive.

If this hypothesis is true, that is feeding the oldest known examples
