| Mississippian Sharks Of The Prospect Hill Formation |
| You can order any of the fossils listed below by clicking here |
The Prospect Hill Formation is of Lower Mississippian age and outcrops near Kalona, Iowa. The deposit
contains a diverse assemblage of conodonts and vertebrates, all of which appear almost exclusively as
microfossils. The vast majority of Palaeozoic shark teeth are actually microscopic in size and unlike their
mesozoic cousins rarely attain large sizes. There are many genera of sharks known from the Palaeozoic
but as most can only be collected by dissolving shales and limestone in acid they are rarely seen for sale.
Offered below is a rare sample of middle Palaeozoic sharks representing close to a dozen different
genera. The Prospect Hill sharks have never been intensively studied and as the species may be
undescribed we have only listed specimens by their genus. All of the specimens listed measure between
~1 and 3 mm unless noted. A photographic ID card showing an enlarged image of each genera will
accompany every order. All specimens are housed in micropalaeontology slides with slip case and cover.
