Diagnosis
ReferenceDiagnosis
F. G. Marx et al. 2015Small-sized mysticete (approx. 2 m in length) corresponding in all preserved features with the diagnosis of Fucaia. Differs from F. goedertorum in having a more elevated posterior portion of the nuchal crest (and thus a more concave supraoccipital shield), an ascending process of the premaxilla that is narrower than the ascending process of the maxilla, an ascending process of the maxilla that extends as far posteriorly as the nasal, a clearly defined (as opposed to interdigitating) naso-frontal suture, a flat, tabular dorsal surface of the involucrum, and an anterior process of the periotic with a dorsally deflected anterodorsal angle.
