Aristonectinae
Aristonectinae is a subfamily of plesiosaurs in the family Elasmosauridae. It includes the Late Cretaceous plesiosaurs Aristonectes and Kaiwhekea, traditionally grouped with the Late Jurassic Tatenectes and Kimmerosaurus in the family Aristonectidae. They are distinguished by the fact that they have a very enlarged skull compared to the width of the body, a moderately short neck and more than 25 teeth in the maxilla.
