This is much more direct evidence of parental care, and it's 100 million years older than other findings suggesting dinosaurs acted this way.

So we are suggesting this was a relatively helpless little hatchling.

When somebody slammed a door in the building, my technician who preparing this felt that.

Most dinosaur embryos are from the Cretaceous period (146 to 65 million years ago).

The only explanation for that is they must have been fed by the mother. That would be oldest evidence of parental care in the fossil record.

We are looking at the very beginning of dinosaur evolution.

These animals do not have any teeth, and since they are ready to hatch, that is strange.

It's a very exciting prospect that means this is the oldest example of parental care.
