On Cleaning an Ancient Fish
The word “fossil” often conjures images of Tyrannosaurus rex skulls, mammoth femurs, or other large bones. But those aren’t the only ones that survive through the millennia, and certainly aren’t the only ones that have importance.
KU Biodiversity Institute graduate students Sarah Spears and Kathryn Mickle study prehistoric fishes. Their fossils are so small that, in order to get them ready for study, Sarah and Kathryn have to use tiny tools to remove excess rock. Sometimes, even metal tools are too rough and inexact, so they switch over to porcupine quills — just sharp and flexible enough to clean tiny fish bones.
