All the items on this page represent vertebrate rich fossil matrix from the Permian of Oklahoma and Texas. Each sample is
different and preserves a different part of the Permian fauna. There is some overlap in the species represented but each is a
great sample from which many vertebrate fossils can be picked. You can order any of the fossils illustrated by

Waurika Microfossil matrix sample collection - medium, fine, extra fine - £15/$25
This collection is ideal for anyone with a keen interest in microfossils or those wishing to pick their own specimens from the
fossiliferous matrix of the Waurika site. The collection consists of
3 different samples, all of which have been sieved and
washed to remove the excess clay. There is a medium, fine and very fine sample included. The coarsest includes pieces of
bone, scale, complete and broken teeth etc. from fish, sharks, reptiles and amphibians. The fine sample still has teeth of
the reptiles and amphibians but shark material is more dominant. The very fine sample is rich in micro shark remains,
especially the denticles. Great stuff and each collection comes with a set of ID cards so that you can name many of the
specimens that you find.
Doleserpeton zone fine - £10/$15
The excellent sample is quite rich in the remains of Doleserpeton.
Predominantly skull plates, jaws are also quite common as well
as other skeletal elements. Other species can be represented in
the sample but it is the highly unusual concentration of
Doleserpeton remains that makes this sample so special. Rare
and highly recommended. We cannot guarantee exactly what you
will find but there are jaws and skull elements in every sample.
Waurika
We have several different samples of fossil rich matrix from the Richard's Spur locality currently available for sale. Each is the
residue of dissolving blocks of limestone or clay and each contains abundant vertebrate remains. The samples are ideal for
schools or the private collector but ideally a magnifier or microscope should be used to sort the material, especially the fine
fraction of any sample. All out matrix is only available in limited quantities and once it is gone, that is it. All the samples came
from the Dolese Brothers quarry near Lawton, Oklahoma. The material illustrated below represents the most comprehensive
collections anywhere on the web. Typically there are 3 grades of material - coarse, medium and fine. We recommend all is
sorted with a microscope but the coarse material could be done with the naked eye. Medium and fine material definitely
require magnification. Even though some samples may come from the same block the difference in particle size means there
can be a significant differences in the types of fossils and species found between the fine, medium and coarse layers. For a
complete overview of the fauna we suggest samples from all three grades.
Black Captorhinus Coarse - £10/$15
Each of the samples from the Black Captorhinus zone
contains fragmentary remains of several different forms but
most material is from
Captorhinus aguti. There are the usual
skull bones, limb bone sections, vertebrae etc. Teeth of
common species also occur as do occasional micro jaws.
White Captorhinus magnus coarse - £10/$15
Each of the samples from the White Captorhinus zone
contains fragmentary remains of several different forms but
most material is from
Captorhinus aguti and Captorhinus
magnus.
There are the usual skull bones, limb bone
sections, vertebrae etc. Teeth of common species also
occur as do occasional jaws sections. Nice material. The tub
shown left is 125ml and is shown alongside a 1 inch gem jar.
Captorhinus zone coarse - £10/$15
The excellent sample is quite rich in the remains of Captorhinus
and
Doleserpeton. Predominantly skull plates, jaws are also
quite common as well as other skeletal elements. Other species
can be represented although we cannot guarantee exactly what
you will find but there are jaws and skull elements in every
sample.
Richards Spur
Permian Microfossil
Matrix
Texas Permian Red Beds
Amphibian zone (fine) - £10/$15
The sample contains the fine fraction from a zone that was particularly rich in microamphibian material.
Doleserpeton is common but Aistopod and other amphibian material has been found on occasion. Nice material.
Waurika coarse matrix - £6/$10
This is for a full pound of medium coarse matrix from
Waurika. It is not as fossiliferous as the finer fractions listed
above, but you do get large shark tooth blades, bones
fragments etc. We don't have much of it and it is priced very
keenly.
Waurika medium matrix - £20/$30
A 100ml tub full of medium sized matrix from Waurika. This material is rich in shark teeth and fish scales plus also
contains other fossils. This is good material for picking as the fossils are all quite large and common.
Archer County Matrix
£4/$6
Nice material quite rich in shark
denticles, teeth and other
vertebrate remains.
Permian Red Beds Matrix I (fine)  - £30/$50
This is a large sample of matrix coming from the famous Permian Red Beds. Sharks dominate the fauna with teeth,
cartilage, skin and mucous membrane denticles being common. Fish, reptile and amphibian fossils are also to be found,
but as this material is representative of a river/lake deposit the freshwater sharks are dominant. The matrix has been
thoroughly washed and screened so that the maximum concentration of fossils has been achieved. Preservation is
excellent and includes partial to complete specimens, many of which exhibit diagnostic features. The particle size is
classed as fine (smaller than 1 mm) and so is heavy on the smallest shark fossils like the denticles and lateral teeth. A
set of specimen identification cards is included.
The images above show a stock photo of a typical collection. The tub weighs ~6 ounces. A tiny fraction of matrix is
seen in the enlargements, which show how obvious the fossils are. There are thousands of fossils in this sample.
We also offer a medium grit size collection with the specimens measuring 1 to 3 mm. The material is housed in a labelled
tub as seen above. There is about 4 ounces of material in the tub, which is practically full to capacity. An enlargement of
some of the typical contents of the medium fraction are seen right and include serrated teeth, double crowned shark
teeth and armor plates. There are notably fewer shark denticles in this fraction as they typically measure less than 1mm.
The enlargements show some of the specimens that are typically found in the medium grit collection. The fossils shown
are primarily shark teeth and skin or mucous membrane denticles.
Permian Red Beds Matrix II (medium) - £30/$50
For collectors not requiring large quantities of matrix we can offer the following samples:
Young County Matrix (fine fraction) - £6/$10
Nice material quite rich in shark denticles, teeth and other vertebrate remains. This fraction contains
the smallest vertebrate fossils that can be found in the Red Beds fauna. The sample comes housed
in a glass vial measuring ~60mm / 2.25 inches tall. The sorting tray in the image contains just a small
fraction of the total sample and measures 2 inches wide.
Young County Matrix (medium fraction) - £6/$10
Nice material quite rich in shark denticles, teeth and other vertebrate remains. This fraction contains
abundant pieces of
Orthocanthus serrated teeth and often complete specimens. The sample comes
housed in a glass vial measuring ~60mm / 2.25 inches tall. The sorting tray in the image contains just a
small fraction of the total sample and measures 2 inches wide.
Permian of Oklahoma Matrix I (fine) - £30/$50
This collection focuses on the Permian of Oklahoma, specifically the Waurika locality. Sharks dominate the fauna with
teeth, cartilage, skin denticles and mucous membrane denticles being common, but the fauna is notably different to that of
the Red Beds with genera such as
Barbclabornia, Janassa, Helodus and Trimerorachis being present (all of which are
rare or completely absent in the Red Beds). Fish fossils are also much more common with various types of scales being
abundant. The matrix has been thoroughly washed and screened so that the maximum concentration of fossils has been
achieved. Preservation is excellent and includes partial to complete specimens, many of which exhibit diagnostic features.
The particle size is classed as fine (smaller than 1mm) but contains a diverse fauna. Comes in a labelled tub as per the
Red Beds collection and includes 1 full set of identification cards (more are available on request).

The Red Beds material is very good but this material from Oklahoma is the best there is. From over 2000 lbs of raw matrix
less than 15 pounds of this material was produced! And that is good for the site because if you collect in the wrong place
you are going to get even less. The richness and quality of this material cannot be understated, so don't let the price put
you off. There are literally thousands of fossils in every sample. The images show the quality of the fossils that can be
pulled from the matrix. You get approximately 3 ounces of material, and this is a very healthy amount of the richest
Permian matrix we have ever seen.

Fossils range from partial to complete, with most being complete and undamaged. There are up to 5 different species of
shark teeth that can be found, twice as many types of denticles, about the same number of fish scales and then there are
the mystery teeth, jaws and claws that appear.
Trimerorachis teeth are common, Archeria teeth can also be found - the
list goes on. Superb material.
Permian of Oklahoma Matrix II (med) - £30/$50
This collection continues that listed previously in that it is designed for lab use (and for dealers) and contains a larger
sample of material that can be divided between several work stations. Being the medium grit fraction of matrix you get more
material (~5 to 6 ounces). Again the sharks and fish dominate the fauna, with large numbers of fish scales and sharks teeth
being immediately obvious. Cartilage, skin denticles and mucous membrane denticles also occur but are far fewer than in
the finer grit size. The amphibians such as
Trimerorhachis and Archeria are more common as are pieces of skull bone and
larger fossils.

Preservation is excellent and includes partial to complete specimens, many of which exhibit diagnostic features. The particle
size is classed as medium (generally 1 to 2 mm) and contains a diverse fauna. Comes in a labelled tub as per the Red Beds
collection and includes 1 full set of identification cards (more are available on request).
