Llanocetus (“Llano's whale”) is a genus of extinct toothed baleen whales from the Late Eocene of Antarctica. The type species, Llanocetus denticrinatus, reached gigantic proportions, with the juvenile specimen reaching an estimated 8 meters (26 feet) in length; a second, unnamed species, known only from three isolated premolar teeth, reached an estimated total body length of up to 12 meters (39 feet). Like contemporary baleen whales, Llanocetus completely lacked baleen in its jaws. It was probably a suction feeder like the modern beaked and pygmy right whales.
