All the specimens listed on this page were dissolved out of a series of Permian limestone blocks from the
Admiral Formation of Oklahoma. It took over 6 months and more than 100 gallons of acid to dissolve one of
the 30 lb blocks and release the bones. The blocks contained thousands of bones from many disarticulated
Permian vertebrates, all of which had been deposited in a narrow water channel. Collected years ago from
the now largely inaccessible Dolese Brothers Quarry (Admiral Formation) in Lawton, Oklahoma. Three
distinct faunas were found in the blocks - one being rich in Captorhinus aguti, another rich in the rare
salamander or newt Doleserpeton annectens and the final block was unusually rich in juvenile pelycosaur
material belonging to Thrausmosaurus serratidens and Mycterosaurus.

Captorhinus aguti
| Captorhinus aguti foot - £90/$140 An excellent quality composite foot of this famous Permian reptile. All bones and claws are complete and have been articulated in the same manner they would have had been in life. The lid of the 1.25 inch display box holding the bones has been taped down but this can easily be removed should you wish to handle the bones. None of the bones are glued in place. Due to increasingly restricted access to the site it has been necessary to increase the price of these feet as it is costing more to acquire this excellent material. |
| Captorhinus frontal lower and upper jaw section Measures ~7 to 10 mm...........£20/$30 the pair |
| Captorhinus jaw with tooth rows Measures ~10 mm......£15/$25 |
| Captorhinus jaw sections. Unsorted. 5 for £15/$25 Picked at random from the group shown. All have some nice teeth and measure ~6 to 10mm long. |
| Captorhinus Vertebrae £6/$10 Six complete centra. Occasionally some have part of the neural arch preserved. |
Captorhinus magnus frontal teeth - £10/$15
These large Captorhinid teeth are belong to
C. magnus based on their large size and
distinct shape. These teeth are from the
frontal upper jaw and are large for the
genus. Each collection consists of 3 teeth
(as shown left) measuring up to ~6 mm long

Doleserpeton annectens Complete limb bone set - £15/$25
This collection consists of 4 very nice limb bones from the tiny Permian
amphibian Cardiocephalus. Each limb bone is complete and represents
four of the bones from the upper and lower limbs. Specimens are ~ 4 to
8 mm long.
Doleserpeton annectens Near complete limb bones - £6/$10
This collection consists of 10 very nice limb bones. Each limb bone is
near complete, usually missing one end or with only minor damage.
Excellent preservation and still great examples. Picked at random but
you will get a variety of different bones.

Doleserpeton annectens Amphibian Skull collection - £20/$30
This is a collection of very delicate specimens from an early ancestor of the newts and salamanders. Each
collection comes in a 1 inch gem jar and contains 2 post frontal bones, 2, two pterygoids, two frontal and two
posterior lower jaws (left and right sides), 2 maxilla/premaxilla and a parasphenoid. We have sold some of these
specimens to another dealer but have only now been able to identify them - thanks to all who helped us put a
name on them. All out Doleserpeton specimens came from a different block.
Doleserpeton annectens Amphibian Skull collection - £12/$20 We also offer smaller collections of this material
which have just one of each element shown above (essentially one side of the skull)

Captorhinus magnus differs from C. aguti by being larger in size but also has only a single row of teeth in each jaw,
unlike C. aguti that has multiple tooth rows at the rear of the jaw.

Captorhinus limb bones - set of two £20/$35
A nice set of two complete Captorhinus limb bones similar to
those shown. The specimens are housed in a 30 mm/1 inch
gem jar and are very well preserved. Although Captorhinus
is a common reptile, complete limb bones are not. You can
find many hundreds of broken specimens for each complete
bone. As such, these are attractive little collections. Keep in
mind the Dolese Quarry is now closed to collecting so few of
these bones will be coming available in future.

Doleserpeton annectens
Doleserpeton Vertebra - £12/$20
A rare and complete vertebra of this
tiny salamander. The vertebra are rare
as they are very small and delicate
and so easily damaged. Each
specimen measures ~ 2mm long and
is a little gem. A rare addition to any
collection.

Doleserpeton Palatine with teeth - £6/$10
Another rare but superb fossil from this early Salamander. The palate was found
in the roof of the mouth and is covered with numerous wickedly recurved teeth
designed to force food down the throat of the animal. Each palate measures ~ 2
to 3 mm long and has excellent teeth like those shown in the images. Fearsome
and not at all common even in micro concentrate.

Doleserpeton Double Vertebrae - £20/$30
Two rare and complete articulated vertebrae of this tiny salamander. Very
occasionally we come across a pair of articulated vertebrae like those shown in
the image. It is rare to find such associated finds in the Richards Spur
micro-matrix but the small size of these specimens means every now and again
they are preserved in this manner. Both vertebrae are complete and are still
articulated as in life when they formed part of the back bone of the animal.

Doleserpeton Foot - £125/$200
A beautiful and very rare composite foot of this
tiny amphibian. The foot measures only 10 mm
long but is complete with all toes, unusual claws
and two ankle bones. All the bones are genuine
fossils. These have to be one of the cutest
fossils we have ever had and the tiny size makes
them really desirable - they are so cute!

Cardiocephalus sp.
Cardiocephalus composite foot - £90/$140
An excellent quality, complete, composite rear foot of this famous
Permian amphibian. All bones are complete and 100% genuine and
have been articulated in the same manner they would have had been
in life. Each claw is complete with excellent preservation. The lid of
the 1 inch display box holding the bones has been taped down but
this can easily be removed should you wish to handle or rearrange
the bones. These are rare specimens from a delicate little amphibian.
The foot measures ~15 mm long with each toe and claw preserved.

Cardiocephalus jaw with teeth - £12/$20
A very good quality partial jaw with teeth. Each jaw has 3 or 4 nice teeth, occasionally
more but they are priced on having 3 or 4. The jaws measure ~3 to 5mm long and
represent about half the total length of the jaw. Cardiocephalus was not a large animal
and as such all of its fossils are small. The jaws are characterised by the far, conical teeth
that are unusually robust for such a small animal. Other amphibians of this size have a
multitude of minute pin teeth but Cardiocephalus seems to have gone the other way and
made do with fewer but larger teeth.

Captorhinus magnus foot - £225/$350
An excellent quality composite foot
measuring 2 inches long and 1.75
inches wide. All the bones and claws
are complete and each is a genuine
fossil. C. magnus feet are much more
rare than C. aguti and approximately
twice as large.
