“…Calcium phosphate ichthyoliths are found in nearly all marine sediments, even red clays (22), where other microfossils have been dissolved by corrosive bottom water conditions. Therefore, ichthyoliths are relatively unaffected by the preservation biases typically found in other microfossil groups.…”

Ray-finned fishes (Actinopterygii) comprise nearly half of all modern vertebrate diversity, and are an ecologically and numerically dominant megafauna in most aquatic environments. Crown teleost fishes diversified relatively recently, during the Late Cretaceous and early Paleogene, although the exact timing and cause of their radiation and rise to ecological dominance is poorly constrained. Here we use microfossil teeth and shark dermal scales (ichthyoliths) preserved in deep-sea sediments to study the changes in the pelagic fish community in the latest Cretaceous and early Paleogene. We find that the Cretaceous−Paleogene (K/Pg) extinction event marked a profound change in the structure of ichthyolith communities around the globe: Whereas shark denticles outnumber ray-finned fish teeth in Cretaceous deep-sea sediments around the world, there is a dramatic increase in the proportion of ray-finned fish teeth to shark denticles in the Paleocene. There is also an increase in size and numerical abundance of ray-finned fish teeth at the boundary. These changes are sustained through at least the first 24 million years of the Cenozoic. This new fish community structure began at the K/Pg mass extinction, suggesting the extinction event played an important role in initiating the modern “age of fishes.”

“…Earlier ichthyolith work mounted tooth residues in optical medium and viewed them using transmitted light microscopy Doyle and Riedel, 1979a, 1979b, 1985. Transmitted light imaging is particularly useful for observing the details of the interior of the pulp cavity and the structure of the enamel cap and may have value for identification of teeth to taxonomic group (Doyle and Riedel, 1979b;Johns, 1993).…”
