Orycterocetus was one of the many predatory whales that swam in the Miocene oceans with included Acrophyseter, Livyatan and Zygophyseter among others. Orycterocetus also has a connection with the whale Aulophyseter on the basis that some of the fossil material attributed to Aulophyseter bears similarities to fossil material from Orycterocetus. This has brought the suggestion that the Aulophyseter fossils in question may be synonymous with Orycterocetus.
