Cacops Temnospondyl amphibian tooth - £6/$10
A single tooth from this rare species of amphibian. Typical specimens measure ~3 to 5
mm long and are beautifully preserved. Each tooth shows the distinct grooving and is
strongly recurved with two carinae. Large amphibian teeth are uncommon at Richard's
Spur, with most amphibian fossils belonging to the tiny
Cardiocephlaus and Doleserpeton.
Miscellaneous
Reptile palates and pterygoids - £4/$6
In amongst the micro fraction of the block we have found
several sections of palate/pterygoid from some unidentified
reptiles. Some typical specimens are shown with an size
ranging from 2mm to 7mm. Each shows some nice teeth that
were in the roof of the mouth of the respective creature. Each
purchase is for 2 specimens, but we do not have too many
available.
Euryodus primus single tooth - £4/$6
A single tooth from this uncommon species. Typical specimens measure ~2 to 3 mm long
and are beautifully preserved. These are short, fat cone shaped teeth with some
similarities to
Cardiocephalus. Euryodus, however, was a much larger animal with a
strongly differentiated dentition. In the front of the jaw were large, spatulate shaped teeth
and in the rear these large cone shaped teeth.
Undetermined Diadectid?
Diadectid? foot - £250/$400
An excellent quality, complete, composite foot of an undescribed
Diadectid?. This specimen comes from the white
Captorhinus
magnus
zone. This specimen is housed in a two inch wide gem jar
(left) with the specimen measuring pretty much a full 2 inches wide
and 2 inches long. All the bones are genuine and complete
including the distinct unguals, which retain a lot of detail. Rare and
from one of the smallest members of the Diadectidae.
Diadectid teeth (no root) - £20/$35 each
These excellent quality teeth are rare at Richard's Spur and it is
the first time we have seen specimens like this. The teeth
belong to an unnamed Diadectid. At the present time we have
both the incisor (right) and premolar type (middle) teeth of this
unusual animal. Specimens measure on average ~ 4 to 5 mm
and are housed in a 1 inch gem jar (as shown left). Compare
these to some of the Diadectid teeth on the Waurika page.
