Recent molecular evidence suggests that pinnipeds evolved from a bearlike ancestor about 23 million years ago during the late Oligocene or early Miocene epochs, a transitional period between the warmer Paleogene and cooler Neogene period.

Pujilla had heavy limbs, indicative of upright movement on land, and flattened phalanges, indicating that they were probably webbed, but not yet flippers.
