Fossil triggers monumental change in our comprehension of whales' evolutionary history

With an estimated weight of 412.3 pounds (187 kilograms) and a length of 8.2 feet (2.5 meters), this newly documented species is roughly the size of a modern-day bottlenose dolphin.

Named Tutcetus rayanensis, this creature belonged to the extinct basilosauridae family, which was one of the earliest groups to become fully aquatic. As revealed in a study published in Communications Biology on Thursday, this diminutive specimen is considerably older than other basilosaurids from the Eocene Epoch.
