FIGURE 4 in Methods for isolation and quantification of microfossil fish teeth and elasmobranch dermal denticles (ichthyoliths) from marine sediments
FIGURE 4. Examples of select taxonomically identifiable fossil ichthyoliths and modern counterparts. All modern ichthyoliths were isolated from specimens in the Scripps Marine Vertebrate Collection. The fossil Myctophidae and Triakidae specimens are from ODP Site 1262, and are 62 million years old. The Scaridae modern teeth are from Smithsonian National Museum of Natural History's Fish Collection and subfossil teeth are from coral reef sediment cores taken off of the coast of Bocas del Toro, Panama, and are approximately 1200 years old.
