| Devonian Sharks Of The Maple Mill Formation |
| You can order any of the fossils listed below by clicking here |
The Maple Mill Formation is of Upper Devonian age and outcrops near Kalona, Iowa. The deposit
contains a diverse assemblage of conodonts and vertebrates, many 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. The Maple Mill 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.

All specimens show better details than the images suggest (we apologise for not being able to provide
better pictures of the specimens) and are typical of the specimens you will receive.
