       When Carinodens was first named it was as Compressidens,‭ ‬however it was later realised that this name had already been used to name a genus of mollusc.‭ ‬Because a name cannot be used more than once,‭ ‬a new name had to be chosen and so Carinodens came into being.‭ ‬Carinodens means‭ ‘‬keel teeth‭’‬,‭ ‬a reference to the shape of the teeth.
       Carinodens is considered to be a relative of other mosasaur genera such as Globidens,‭ ‬and the teeth of the type species certainly do bear a similarity.‭ ‬This indicates that Carinodens fraasi may have had a greater focus upon hunting rough shelled prey like ammonites.‭ ‬Other species of Carinodens have been noted as more gracile and with less specialised teeth,‭ ‬and perhaps hunted for faster less armoured prey such as fish and squid.
       Carinodens lived towards the end of the Cretaceous period,‭ ‬and although undoubtedly a hunter itself,‭ ‬these mosasaurs were comparatively small compared to the truly big mosasaurs such as Mosasaurus and Hainosaurus which swam in the same waters,‭ ‬and‭ ‬which themselves would have hunted other large marine reptiles about the size of Carinodens.
