Discussion.

A single relatively small and slightly eroded otolith of 1.7 mm in length is interpreted as representing an unknown species of the genus Taaningichthys and is characterized by a relatively elongate shape (OL:OH = 1.4), a regularly curving ventral rim, a nearly flat dorsal rim, a distinct rostrum and a dorsally shifted posterior tip, and a flat inner face, with a supramedian sulcus with a long ostium and a short cauda (OCL:CCL = 2.0).

Subfamily Diaphinae Paxton, 1972 (sensu Martin et al. 2018)
