Over millions of years of evolution, the great ocean fish has had a way of adapting to the environment by laying eggs. Oviparous sharks lay large eggs, often wrapped in leather-like skins with tassels that anchor them to rocks or weeds.

Because of the soft, perishable structure, fossil shark eggs are extremely rare. While the specimen has just been discovered, it has been quite perfect over 310 million years. This fossil egg is found in the area near Doncaster, South Yorkshire, England.

Sci-News page said fossil shark eggs were taken to preserve at the Doncaster museum.

Dean Lomax said the scientists will continue to look for more fossils in the area and hope to obtain fossil samples of a fish that has formed.
