Wondered if you guys had any thoughts on recreating the large prehistoric shark Charcharocles Megalodon, assumedly using an artificial womb, as is now being done with some modern sharks. Would we be able to extract ancient DNA from the remains we find, which so far are only teeth and vertebrae, since I believe this shark is thought to have disappeared around 4 million years ago, or would we just have to create a genome for our own giant shark?
