Argoselachus atrox(Atrocious shark of the Argo)
Argoselachus was a close relative of the modern tiger shark that lived from the mid-Oligocene but died out in the Miocene. It's so closely related to the tiger shark that some scientists prefer it to be classified under Galeocerdo but the existing evidence could point either way. More fossils are needed to settle the debate. Argoselachus ruled as apex predator in the Mediterranean and fed on pinnipeds, whales and other sharks. Measuring 10.7 meters long and weighing 10.1 tonnes, few could challenge this sea monster. At age 15, they reached reproductive age and could mate anytime they wish. Nursery areas in shallows are refuges for the pups. It's surmised this shark could live for over seventy years. Argoselachus was driven to extinction by Megalodon and the continuing climate change. Its slow rate of reproduction(only twenty pups per birth and fifty if lucky) combined with competition and predation from a larger predator didn’t help.
