Do megalodons have preadators

Answer 1

As strange as it may seems, C. megalodon could have been a prey of other Miocene very large predators, like Livyatan melvillei.

This predatory odontoceti cetacian could reached the same size of extant sperm whales, or even larger. Confirmed length of more than 17 meters is accepted today by paleontologists, but VERY FEW fossils of this apex predatory whale were found. Larger individuals are a probabilistic certitude.

Moreover, Livyatan melvillei had not only teeth in BOTH upper and lower jaws - unlike sperm whales - but they had much larger teeth than megalodon (36 cm length confirmed).

(As a matter of fact, Livyatan melvillei had the largest teeth EVER found in a carnivorous predator, incuding tyrannosaurus, pliosaurs, mosasaurs and megalodons!)

Last but not least, Livyatan melvillei most probably hunted in packs, and were formidable predators.
