Eromangasaurus was first named by Benjamin P. Kear in
2005 and the
type species is
Eromangasaurus australis. Benjamin P. Kear originally named QM F11050 as
Eromangasaurus carinognathus. This nominal has priority over
E. carinognathus, and therefore the latter is a
junior synonym of
T. australis. Later studies of the holotype by Kear pointed out that this species is distinct enough from the type species of
Tuarangisaurus to be placed in its own genus.
Eromangasaurus was the only available name for the new combination
Eromangasaurus australis.
E. australis is widely accepted today as the correct name for QM F11050. The
generic name is derived from
Eromanga, in reference to the Eromanga Basin in which the holotype was found, and
saurus,
Greek for "lizard". The
specific name is named after Australia, in which the holotype was found. ==Description==
