Dagonodum is an extinct genus of ziphiid cetacean known from Tortonian age marine deposits in the Gram Formation in Denmark. There is only one known species, Dagonodum mojnum.{{Cite web|url=https://www.gbif.org/species/124955304|title=Dagonodum mojnum|website=www.gbif.org}}

Etymology

The genus name is a reference to the god Dagon, worshiped as the head god and as a deity of prosperity in ancient inland Syria, but best known from H.P. Lovecraft's short story, where he is instead depicted as deep-sea deity. The species name is a reference to the word for "goodbye" in the local South Jutlandic dialect where the fossils were found. The word, "mojn", is of German origin, where it is used as both a greeting and a farewell.

Taxonomy

The species is distinguished by its two pairs of mandibular tusks and long snout. It also possessed a long neck, leading to speculation that it wasn't well suited to deep-dives.

Feeding

The species is notable for its difference from other ziphiidae of the period in that it seems to be less reliant on suction feeding.{{Cite journal|title=A new specimen of Ziphiidae (Cetacea, Odontoceti) from the late Miocene of Denmark with morphological evidence for suction feeding behaviour|first1=Benjamin|last1=Ramassamy|first2=Henrik|last2=Lauridsen|journal=Royal Society Open Science|year=2019|volume=6|issue=10|pages=191347|doi=10.1098/rsos.191347|pmid=31824732|pmc=6837206|bibcode=2019RSOS....691347R}}
