Abstract Otoliths are common and diverse in the Neogene of tropical America. Following previous studies American otoliths lanternfishes (Myctophidae), marine catfishes (Ariidae), croakers (Sciaenidae), cusk-eels (Ophidiiformes), we describe here gobies (Gobiidae). The Gobiidae represent richest fish family, with more than 2000 species worldwide about 250 In fossil record too they family We have investigated sampled from Ecuador, Pacific Atlantic Panama, Costa Rica, Dominican Republic, Venezuela, Trinidad, ranging age late Early Miocene (late Burdigalian) to Pleistocene (Calabrian). Most studied material originates collection expeditions Panama Paleontology Project (PPP). Our study represents first comprehensive America, recognize 107 species, which 51 new science, 35 open nomenclature, 19 that also live region today. Previously, only two otolith-based goby been described dominant Gobiosomatini, particularly genera living over soft bottoms or deeper water such as Bollmannia , Microgobius Antilligobius Palatogobius . Another purpose our is provide a account extant consider necessary for an adequate identification interpretation otoliths. 130 gobiid figured 106 them comparison. present morphological analysis characterization basis Problems commonly arise specifically addressed discussed. A comparison history America reveals high percentage shared between basins during Late (Tortonian Messinian) at least 11 6 Ma. recording gap on side across Pliocene allows again (Calabrian, 1.8 0.78 Ma), shows complete lack species.
