1.45" Cyphaspis Trilobite - Devil Horns
Here is nice example of the Devonian trilobite Cyphaspis sp. sometimes referred to as the "Devil Horn" Cyphaspis for obvious reasons. The spines are natural and the preparation is very nice. This specimen is quite large for the species at nearly 1 1/2 inches in length including the spines.
