This is an Exceptional and Rare Cyphaspis carrolli trilobite from Black Cat Mountain. It is named after famed trilobite expert and digger Bob Carroll.
This is a well preserved trilobite and an excellent example of this species. The location where they come from is well known. Because the rock is so hard the trilobites are preserved in great detail. The detail in this trilobite is amazing. The tail is slightly disarticulated.
This Exceptional and Rare Cyphaspis carrolli trilobite is excellently prepared with air abrasive technology. It is fully inflated with especially detailed head section. The spines are visible including the thoracic spine n the middle of the back. It is not free standing but lying on the back of the trilobite. Because there is only one location where they are found, they are in high demand. This is a prone trilobite in life position. There are many various trilobites found in this deposit.
Black Cat Mountain is a Devonian deposit. Because that part of Oklahoma was once the bottom of a shallow salt water sea, fossil trilobites can be found. This Exceptional and Rare Cyphaspis carrolli was buried in soft mud that preserved it quickly. Because it was buried quickly, scavengers were not able to eat or tear it apart. The rocks of the Haragan formation are very hard but the rock can be removed by air tools. They are Devonian from the Haragan formation of Clarita, Oklahoma.
This Prone trilobite is very showy because of the rich caramel color and the creamy beige color of the rock. It is 1/4 inches long and sits on a square shaped matrix that is 2 1/4 by 2 1/4 inches.
