Palaeozoic
Microfossils
Lower Devonian - Haragan Fm - White Mound - £6/$10
All of the microfossils listed are sold as unsorted matrix samples.
Sample size varies depending on the concentration of fossils,
ranging from a small capsule to a glass vial of material.
Each contains a large number of fossils.

Many samples come with an ID card to allow you to name many
of the species that you find.
Lower Devonian sample from the White Mound type site locality for the Haragan
Formation of Oklahoma. This is one of the richest samples we have seen.

Middle Devonian sample from the Silica Shale of Sylvania, Ohio. The deposit contains a prolific ostracod fauna
that is exquisitely preserved. The sample also contains a Tentaculitid fauna that is more abundant than we
have ever seen before.

ostracods, unusual egg cases and other forms of invertebrate.
Upper Silurian - Beech River Formation -  £4/$7

ostracod fauna that is very similar to that obtained from the Haragan Formation of Oklahoma.
Pennsylvanian - Gene Autry Shale - £4/$7 - Vial £20/$30
An unusual fauna from the Pennsylvanian of Oklahoma. The fauna is distinct with strange forms of ostracods
and foraminifera, in addition to vertebrate remains and common invertebrates.
Nodosinella glenensis
Foraminifera
Emphissites nodosus
Ostracod
Fusulinids
Pennsylvanian - South Bend Shale - £4/$6 - Vial £15/$25
An unusual fauna from the Pennsylvanian of Texas. Practically every small fossil that weathers out of this deposit is a
perfectly preserved three dimensional fusulinid. This sample contains dozens of specimens with practically no matrix
Permian - Bennet Shale - £4/$7
A typical marine fauna that is rich in fusulinids. Each sample also has abundant examples of the major typical marine
groups (crinoids, bryozoans etc.) all of which show wonderful preservation.
Permian - Johnson Shale - £4/$7
An excellent sample very rich in fusulinids and other microfossils from the Permian of Kansas. Preservation is fabulous
and in our opinion this is one the best Permian sample we have ever had. Hours of work in each sample
Lower Devonian - Frisco Limestone - £6/$10
Lower Devonian sample from the Frisco Limestone of Oklahoma. The deposit contains a diverse ostracod
fauna that is very similar to that obtained from the Haragan and Cravat Formations.    
Middle Devonian - Olentangy Shale - £6/$10
Middle Devonian sample from Ohio. The deposit contains a prolific ostracod fauna that is exquisitely preserved.
The sample also contains a Tentaculitid fauna.
Ordovician - Pooleville Member, Bromide Formation - £10/$15 (three samples)
Rich in ostracods and all manner of marine invertebrate remains, including trilobites, the samples represent the
upper, middle and lower sections of the Pooleville Member of the Bromide Formation.

Upper Silurian sample from the Brownsport Group of
Tennessee. The deposit contains a rich microfauna.
Haragan Fm - Trilobites facies
£10/$15
Middle Devonian - Arkona Shale - £5/$8
Middle Devonian sample from Canada. The deposit contains a prolific ostracod fauna that is exquisitely
preserved. The sample also contains a Tentaculitid fauna.
Mississippian - Pella Formation - £3/$5 - Vial £20/$30
Mississippian of Iowa. A bright white deposit rich in microfossils, including many tiny ostracods.
Mississippian - Salem Limestone - £3/$5 - Vial £20/$30
Mississippian of Indiana. Extremely rich in foraminifera.
Pennsylvanian - Lester Limestone - £3/$5 - Vial £10/$15
Pennsylvanian of Oklahoma. Extremely rich in bryozoans and echinoderm remains.
Pennsylvanian - Stull Shale - £3/$5 - Vial £20/$30
Extremely rich in bryozoans and some ostracods
Pennsylvanian - Holdenville Shale - £4/$7
Pennsylvanian of Oklahoma. Good ostracods and occasional vertebrate remains.
Pennsylvanian - Griley Limestone -  £3/$5
Pennsylvanian of Oklahoma. Good bryozoans.
Pennsylvanian - Francis Shale - £4/$6
A superbly preserved ostracod fauna.
Permian - Florena Shale - Coarse or Fine £3/$5 each
An excellent sample rich in fusulinids and other microfossils from the Permian of Kansas.
Pennsylvanian - Dekalb Limestone - £3/$5
Ordovician - Arnheim Formation - £3/$5
Includes brachiopods and various molluscs
Ordovician - Maquoketa Shale - £3/$5
Includes nautiloids and bivalves
Ordovician - Mountain Lake Member, Bromide Formation - £6/$10(two samples)
The Mountain Lake Member differs considerably from the Pooleville Member of the Bromide Formation. In
the Mountain Lake crinoidal debris is particularly obvious and although common the ostracods are not nearly
as abundant. Microbrachiopods are common. The two samples represent and upper and lower section of the
Mountain Lake. The lower is from the
Mimella extensa zone, whereas the upper is from the Oxoplecia filosa
zone. In both samples juveniles of the respective specimens can be found. Preservation is excellent with the
ostracods and microbrachiopods being complete.
Mississippian - Glen Dean Limestone - £3/$5
Good bryozoans and occasional ostracods.
Permian - Hughes Creek Shale - £3/$5
Permian of Texas. Nice and abundant fusulinids
Pennsylvanian - Bluff Creek Shale, Graham Formation, Texas  - £3/$5
For those wanting an even greater division of microfossil matrix, we can offer a collection of 30, 40, 60 and 80+ mesh
size samples
from the rich middle section of the Bromide Formation. Each sample preserves a sightly different fauna
with many fossils seen in one fraction not found in any of the others. By separating the samples it makes sorting
easier as you do not need to constantly zoom in and out as particle size changes. This is an excellent collection.
Ordovician - Middle Pooleville, Bromide Formation - £12/$20 (four mesh sizes)
Middle Devonian - Cerro Gorda Shale - £3/$5
From the Devonian of Iowa this fine fraction of matrix contains some of the oldest foraminifera.
Lower Devonian - Birdsong Shale Bryozoan Zone- £4/$7
Lower Devonian sample from the Birdsong Shale of Tennessee. This sample is from the upper
bryozoan zone and consists almost entirely of bryozoans, almost at the expense of all other fossils
and even matrix! An incredibly rich sample with hundreds, probably 1000 fossils.

matrix please see our
Gotland Pages
Ordovician - Ibex Formation - £5/$8
A super rich sample consisting of almost nothing but ostracods. Great preservation and an unusual sample.
