Large globular gabella
Prepared in a "swimming" position
An incredible Crotalocephalina gibba trilobite, of the order Phacopidea, discovered in Haman Laghdad, Morocco.
It dates from the Devonian Period, 360 million years old
Typically these trilobites have eyes low down on the sides of the cephalon, a large, bulbous glabella, and dagger-like projections on the ends of the pleura.
This specimen has been prepared free of the matrix, in a "swimming position", and is extremely detailed.
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.
A quality trilobite, and a terrific addition to a collection.
