Remarks

The otoliths of Albula are uncommon in our material: only four specimens from the “Stone City beds” were found. These otoliths share many features with those of the extant Albula , but unfortunately, they are not well preserved. Additionally, Nolf & Stringer (2003) reported five Albula otoliths from the Yazoo Clay of Louisiana and Ebersole et al. (2019) four otoliths from the Lisbon Formation of Alabama. A study of albulid otoliths is further provided by Frizzell (1965), but it seems that his otolith-based genera and species were just established to reveal tentative evolutionary lineages. These genera and species have been reviewed by Nolf (2013).

Stratigraphic and geographic distribution

Lutetian: “Stone City beds”, Texas. Bartonian: “upper” Lisbon Formation, Alabama. Priabonian: Yazoo Clay, Louisiana.
