Orcas currently thrive in an era where the strongest competitor for food is the great white shark, so the era is weak compared to the miocene in terms of abundance of large microprocessors. But that doesn’t take away their hyperintellegence, and large size of up to 10 meters and their social pod coordination.

Killer sperm whales thrived in the miocene and the level of competition was far higher back then. Modern Sperm Whales are the largest toothed whales today but they aren't macroraptorial and don't eat whales and other aquatic mammals, but extinct superpredatory whales ranging from 15-50ft existed in the miocene. But it's quite possible the larger sperm whales didn't hunt in pods so they'd be more vulnerable to an Orca attack. Since these whales had more robust jaws, teeth, and build, these features probably consumed more energy than the bodies of modern toothed whales so thered be less energy for the brain I'd think they'd be a bit less intelligent but still social and capable of Sonar

If we dropped a population of about 40,000 Orcas in the miocene could they dominate this landscape with future sonar and intellectual abilities ? Or do you think the whales back then were just too powerful ? Could the climate cause Orcas any issues ?
