Remarks

Bregmaceros otoliths are sometimes tricky to identify at the species level ( Přikryl et al. 2016) due to their often insufficient diagnostic features. Several features, including an enlarged part in the antero-ventral area that forms a conspicuous sharp postero-ventral angle and an evident concavity in the dorsal rim, are very consistent in the investigated specimens, and therefore we have assigned them to B. troelli (or a closely related species complex). The species can be very abundant in some of the levels, such as the Landrum Member. In the upper sample of the Yazoo Clay in Louisiana, nearly 92% of the total assemblage was comprised of this species ( Nolf & Stringer 2003).
