| 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 studied
and many species may be undescribed.
All of the specimens listed measure between ~1 and 3 mm unless noted and are housed in micropalaeontology
slides with slip case and cover. PLEASE ORDER BY SPECIMEN NUMBER. Many of the sharks belong to rare
types we have not been able to identify from the literature. Where possible we have listed the genus we think most
strongly corresponds to the available specimen. The slides are not labelled with genus or species, only geological
formation as we did not want to put anything definitive on them in case it turned out to be inaccurate. We will leave
this to the purchaser.
