Sharks’ non-bony skeletons had been considered to be the template before bony interior skeletons developed, but a fresh fossil breakthrough implies otherwise.
The finding of the fish that is 410-million-year-old with a bony skull indicates the lighter skeletons of sharks could have developed from bony ancestors, as opposed to the other means around.
Sharks have skeletons made cartilage, that is around half the thickness of bone tissue.
