Super "Devil Horned" Cyphaspis trilobites
Amazing detail of devil horns
Interesting display preparation
Cyphaspis Trilobite 2
An outstanding trilobite plate, displaying two species of trilobite, discovered in Alnif, Morocco.
It dates from the Devonian Period, 360 million years old.
There are two wonderful specimens of the "Devil-Horned" Cyphaspis issomourensis trilobite. These are complete trilobites, and clearly display the "Devil Horns", projecting upwards from the glabella. They have stalked eyes, long genal spines, and a long spine projecting backwards from the middle of the thorax.
The other two partial trilobites are of the species Metacanthina, one clearly displaying the typical pygidium.
Trilobites ("three-lobes") are extinct arthropods that form the class Trilobita. They appeared in the Middle Cambrian epoch and flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Late Devonian extinction, all trilobite orders, with the sole exception of Proetida, died out.
The last of the trilobites disappeared in the mass extinction at the end of the Permian about 250 million years ago.
This is a fantastic display piece.
