Is anyone good with otoliths? I think, but I am not sure that this is a fish otolith from the Upper Pliocene Jackson Bluff Formation, Leon County, Florida. I apologize for the picture quality but it is as good as I can get from my digital microscope. Approximately 1 cm in length, I would like to know what kind of fish it was from, if possible and if it is an otolith. Thanks Mike

Mansfield (1930) described the Jackson Bluff (Chocatawahatchee) Formation species as Ecphora qudricostata umbilicata. Campbell (1993) and Lauck Ward (personal communication) agree that all named species and subspecies of Ecphora from the Upper Pliocene are variations of a single species E. quadricostata. Both consider Ecphora bradleyae Petuch, 1986 as the only other valid Upper Pliocene Ecphora. Reference Campbell, Lyle. 1993.
