The discovery of dozens of tiny sharp teeth together with egg capsules proves the existence of a 230 million-year-old shark nursery, according to a paper published in the latest Journal of Vertebrate Paleontology.

The discovery represents the first occurrence of egg remains and young shark teeth in one area.

"It allows the direct correlation between those eggs and the young and the interpretation of the area as a shark nursery," lead author Jan Fischer explained to Discovery News.
