Carinodens (meaning 'keel teeth') is a genus of mosasaur. It was named in 1969 as a replacement for Compressidens, which was already in use for a mollusk. Measuring approximately 3.5 metres (11 ft) in length, it is one of the smallest known mosasaurs. It is widely considered a sister taxon to Globidens. It also had round, blunt teeth for crushing primitive clams and oysters. Most cranial elements have been found in The Netherlands.
