While the discovery of dinosaur skeletons is not a new tale, a research team has discovered evidence of a possible dinosaur nest that may have had a babysitter to look after the young dinosaurs.

According to a new study published in the journal Cretaceous Research, University of Pennsylvania researchers, discovered a rock slab containing fossils of 24 very young dinosaurs and one older individual suggested that a group of hatchlings was overseen by a caretaker.

The researchers believed that this specimen might offer evidence of post-hatchling cooperation, a behavior exhibited by some species of modern-day birds. The older juvenile might well have been a big brother or sister helping care for its younger siblings.The 24 younger animals appeared to be similar in size. Various observations suggested that they had already been hatched, as there was no evidence of eggshell material. 

Other paleontologists have identified even smaller individual psittacosaurs and the ends of their bones were well developed, which indicated that they were capable of moving around.

Brandon Hedrick part of the research team at the University of Pennsylvania said it certainly seems like it might be a nest, but they weren't able to satisfy the intense criteria to say definitively that it was.
