Devonian - New Albany Shale - £10/$15 - Vial £25/$40
The New Albany Shale of Indiana is a late Devonian deposit. The shale breaks down in acid to produce a residue
rich in quartz crystals and conodonts. Occasionally other vertebrate remains can be found, but this material is most
notable for the large number of excellently preserved conodonts that it contains.
Polygnathus
Hibarella
Devonian - Beechwood Limestone -  £10/$15 - Vial £25/$40
The Beechwood Limestone of Indiana is a late Devonian deposit. It is very similar in nature and faunal make-up to
the New Albany Shale and comes from the same geological section.
All of the microfossils listed are sold as
unsorted samples. Sample size varies
depending on the concentration of fossils.
Sample size varies from a small capsule to a
vial of material. Each sample contains a
large number of fossils.

Most samples now come with
identification cards (as shown) so you
name many of the species found.
Mississippian - Chappel Limestone - £10/$15 - Vial £25/$40
From the Mississippian of Texas, the Chappel Limestone contains a diverse conodont fauna. Occasional shark
teeth can also be found. ID card provided with each sample.
Mississippian - Prospect Hill Fm - £10/$15 - Vial £25/$40
Mississippian of Iowa the Prospect Hill Formation contains a diverse conodont fauna.
Shark teeth and fish remains are also quite common. See our page Prospect Hill Sharks
Devonian - Genundewa Limestone - £10/$15 - Vial £25/$40
From Eighteen Mile Creek in New York, this sample was collected from a compacted dark shale at the top of the
formation. It is rich in conodonts and has abundant shark/fish remains. Much is fragmentary due to having been
deposited in a high energy environment but the images show the typical specimens that can be picked from the
sample. No ID card at the present time but we are working on it.
Pennsylvanian - Gene Autry Shale - £10/$15
From the Pennsylvanian of Oklahoma, the Gene Autry Shale contains a basic conodont fauna
with occasional shark teeth and fish/shark scales. Foraminifera are extremely abundant.
Cretaceous - Acto Formation - £10/$15
From the Cretaceous of Texas this sample contains fish and ray teeth with occasional shark and saw fish remains.
A very interesting sample of material that is quite rich in vertebrates.
Cretaceous - Kemp Formation - £10/$15
From the Cretaceous of Texas this sample contains occasional fish, shark and ray fossils and abundant foraminifera.
Another very interesting sample that is remarkably rich in fossils.
Pennsylvanian - Eudora Shale - £10/$15
Pennsylvanian of Kansas. The Eudora Shale contains a basic conodont fauna with occasional shark teeth and
fish/shark scales. Foraminifera are abundant.
Miocene - Round Mountain Silt - £12/$20
Miocene of California. This is classic Shark Tooth Hill type material containing fish, ray and some shark material.
