Long, long ago .....

The actual size of this fossil Trilobite is roughly three-quarters of an inch. When my friend, Linda, sent me 400+ photos of things that had belonged to my brother and my parents, I was thrilled to bits to notice this Trilobite, as I didn't have one of my own, and so asked her to send it to me with all the other things. Can't remember where this came from - suspect we may have given it to my mother or my brother, many years ago. I'm pretty sure it's not one that I collected decades ago, when I was still living in England and in HIgh School, studying Geology. I remember well going to the Wren's Nest, Dudley, a well-known fossil site.

"Trilobites (meaning "three lobes") are a well-known fossil group of extinct marine arthropods that form the class Trilobita. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (526 million years ago), and they flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Devonian, almost all trilobite orders, with the sole exception of Proetida, died out. Trilobites finally disappeared in the mass extinction at the end of the Permian about 250 million years ago. The trilobites were among the most successful of all early animals, roaming the oceans for over 270 million years." From Wikipedia.
