| Abstract: |
Studying the ecology of ancient organisms requires a tremendous amount of data, as in the case of prehistoric sharks where our knowledge is based mostly on teeth. Shark Tooth Forensics is a participatory science project tackling the problem of deciphering the ecology of ancient sharks with assistance from public school students. Traditionally, paleontological data collection protocols use research staff or a cadre of trained volunteers to collect paleontological data, whereas participatory science provides a means to increase the number of people involved in paleontological research. Students contributing to our project search for fossil shark teeth in sediments from various geologic time periods, and measure and record the teeth they discover for accessioning in natural history museums. Statistical analyses reveal that middle school students provide measurements of shark teeth that are indistinguishable from those same measurements taken by research staff. However, it is necessary to collect data from large student populations, ~10–30 students, before obtaining a statistically reliable sample. In addition, we find students are able to recognize shark teeth from a variety of species, not just stereotypical triangular teeth of species like the Great White (Carcharodon carcharias). Teachers can utilize Shark Tooth Forensics curricular activities that use student data in curriculum as a way to gain more personal investment. We estimate over 2,000 students have already participated, and with the potential for this project to last for decades, many thousands more will have the opportunity to discover fossil sharks and reconstruct the lives of these ancient fish.
