Short summary
Extant pygmy and dwarf sperm whales (Kogia spp.) are known as small-sized and enigmatic relatives of the great sperm whale Physeter. Here we describe Koristocetus pescei, a new fossil kogiid from the late Miocene (ca 7 million years ago) of Peru. The description of this new form evokes a long history of morphological and ecological diversity in fossil kogiids, thus suggesting that our comprehension of the evolutionary history of diminutive sperm whales is still far from being exhaustive.
