The early cetacean mammal discovered in Pakistan is the extinct genus Pakicetus.

Known from fossils found in the Kuldana Formation, Pakicetus dates back to the early Eocene Epoch (approximately 48.5 million years ago). It is recognized as one of the earliest whales and is notable for being the first cetacean discovered with functional legs, indicating it was capable of terrestrial locomotion despite its aquatic environment in the ancient Tethys Sea.12
