Mycteriacetus is an extinct genus of dolphin from the Early Miocene (Burdigalian) of northeastern Italy. The type species is M. bellunensis.
Mycteriacetus is named after the Yellow-billed stork (Mycteria ibis) because the bill of that species is as long as the rostrum of Mycteriacetus.[1]
Mycteriacetus bellunensis was originally named as a new species of Eurhinodelphis, E. bellunensis, by Pilleri (1985).[2] However, Bianucci and Landini (2002) transferred this species to Argyrocetus, creating the new combination A. bellunensis.[3] Lambert (2004) eventually recognized E. bellunensis as sufficiently distinct from Eurhinodelphis and Argyrocetus to warrant a new genus, Mycteriacetus.
