Maiabalaena is an extinct genus of baleen whale from the Oligocene of Oregon 33 million years ago consisting of one species: M. nesbittae. It lacks any form of dentition, indicating that baleen whales first evolved tooth loss before evolving baleen. It was likely an efficient suction feeder.[1] The species name is in honor of Washington state's leading paleontologist, Elizabeth Nesbitt.
