Trinacromerum was 3 meters (9.8 feet) long. Its teeth show that it fed on small fish.[1]
The long flippers of Trinacromerum enabled it to achieve high swimming speeds.[1] Its physical appearance was described by Richard Ellis as akin to a "four-flippered penguin."[2] Its name means "three tipped femur".
