Megalodon was the biggest shark of the ocean 23 million years ago. It could grow up to 60 ft, and its jaw bite was stronger than a T. Rex’s. So you might think there was nothing that could stop it. But even this massive shark had enemies, and their fights could be lethal.
– Cetotherium was a baleen whale from the Cetotheriidae family. It lived from the mid-Miocene period to the Early Pliocene period and grew up to 15 ft. Fossil records have revealed that Cetotherium would be Megalodon’s top target.
– Zygophyseter lived in the late Miocene period, some 11 to 7 million years ago, and it cruised the Mediterranean region. From fossil records, paleontologists have gathered that Zygophyseter grew to be 20 ft long. It had an asymmetrical cranium, which is commonly associated with high-frequency sound production and echolocation.
– Aulophyseter was a predatory whale, very similar to modern-day sperm whales. Sperm whales are the largest predators and the largest toothed whales today. Aulophyseter lived in the Miocene period.
– Brygmophyseter was a highly predatory sperm whale. The only known fossil is a nearly complete skeleton that is dated at 14 to 15 million years old. From it, paleontologists gathered that Brygmophyseter was 23 ft long. Theories suggest that it swam in pods as other whales do.
– Rhamphosuchus is one of the largest known crocodiles ever to roam Earth. The world wouldn’t even be aware of the existence of Rhamphosuchus if it wasn’t for the discovery of incomplete sets of fossils that are mostly teeth and skulls. Rhamphosuchus is estimated to have been 26 to 36 ft long.
– Livyatan and Megalodon were 2 of the most terrifying creatures to roam the oceans, and both lived during the Miocene period. Livyatan was a whale that was 60 ft long and weighed up to 50 tons. Its largest teeth were up to 14” long.
