February's whale is Cophocetus oregonensis, a species that, as the name suggests, is unique to the Oregon coast: the type specimen was unearthed near the Yaquina Bay Lighthouse in Newport. Bones that may be attributable to another species of Cophocetus have been uncovered near San Mateo, California. The Newport specimen - currently on display in Paleolab - consists of an incomplete skeleton including a vestigial pelvis, a relic from its distant, land-dwelling ancestors. Cophocetus was a member of the Pelocetidae, an extinct family of whales found worldwide during the Miocene. Pelocetids were early balaenopteroids, making them not-too-distant relatives of modern rorquals, including humpback and blue whales.
