Peregocetus
Sign in to savePeregocetus is a genus of early whale that lived in what is now Peru during the Middle Eocene epoch. Its fossil was uncovered in 2011 in the Yumaque Member (Paracas Formation) of the Pisco Basin at Playa Media Luna by a team consisting of members from Belgium, Peru, France, Italy, and the Netherlands. Parts recovered include the jaw, front and hind legs, bits of spine, and tail. Olivier Lambert, a scientist at the Royal Belgian Institute of Natural Sciences and lead author of the study, noted that Peregocetus "fills in a crucial [knowledge] gap" about the evolution of whales and their spread.

Peregocetus is a genus of early whale that lived in what is now Peru during the Middle Eocene epoch. Its fossil was uncovered in 2011 in the Yumaque Member (Paracas Formation) of the Pisco Basin at Playa Media Luna by a team consisting of members from Belgium, Peru, France, Italy, and the Netherlands. Parts recovered include the jaw, front and hind legs, bits of spine, and tail.

Peregocetus is the first recorded quadrupedal whale from the Pacific Ocean and the Southern Hemisphere. The discovery reveals that protocetids reached the Pacific Ocean and attained a near circumequatorial distribution while retaining functional weight-bearing limbs.
