Baby Meg: the size of Daddy shark?

New research into the developmental biology of the gigantic prehistoric shark, known as the megalodon, gave birth to 2-meter-long pups that likely ate fellow embryos in the womb.  A recent research collaboration, led by paleobiologist Kenushu Shimada of DePaul University (Chicago, IL, USA), studying the reproductive biology, growth and life expectancy of megalodon has uncovered some fascinating insights into the scale and development of the prehistoric beast [1]. These details have previously been difficult to establish due to the cartilaginous nature of the megalodon’s skeleton which breaks down more easily than bone, leaving fewer opportunities for fossils to form.  Vertebrae fossils from the giant shark do exist, however, with one specimen housed at the Royal...
