The collection has been completely inventoried and organized, and Curatorial Assistant Andrew Williston is entering collection data, including the original locality data, into MCZbase. Ichthyology intern Rex Passion completed the collection inventory and collection data review. "Otolidis are a valtiable resource in defining fish species and studying fish ecology," says Williston. "Growtli rings in otoliths can be sttidied for aging indiridual fish. They can be tised to identify fish remains in the stomach contents of marine predators like dolphins, and fish diets can be studied using stable isotope analysis of otoliths. And since otoliths ai e often fossilized, they can be compai ed to modern otolidis to better understand the diversity of fossil ;.
