Megalodon vs Livyatan

A depiction of what might have been the biggest 1v1 battle ever to happen on this planet.
These two giant macro predators shared the oceans for millions of years.
Although the violent encounters were probably rare and they tended to avoid each other, sometimes the circumstances were set for an epic clash.
A pair of Livyatans with a sick calf echo-located a very hungry female megalodon from more than half a kilometer away..and male Livyatan decided to actively protect the calf. He charged ahead picking up speed, knowing that a shark cannot directly challenge his charge, as head on collision of two 50 ton bodies at 40+ km/h would be too risky ever for the gigantic shark, leaving it stunned and face smashed.
However, the hungry large Megalodon did not back down. Confident in her direction changing ability, she swam right at the whale and made swift evasive move in an attempt to deliver a devastating sideways bite..only to expose her large fin to the the biggest gripping bite in Earth history.
After a massive and bloody struggle, the two creatures broke out of it, each leaving a bloody cloud behind.
Megalodon, sensing that a major part of the fin was missing, dove down in retreat. His cetacean foe, with a few massive new gashes on his side, sped ahead and out of harm's way.
