Echovenator ("echolocation hunter") is a genus of primitive odontocete from late Oligocene (Chattian) marine deposits in South Carolina belonging to Xenorophidae.[1]

Description and paleobiology

Echovenator is distinguishable from other xenorophids in having a paranaris fossa and fused fronto-nasal and maxillo-premaxillary sutures.[2] The earbone structure shows that this odontocete was clearly capable of echolocation.[2]
