FREE: 500 million year old Trilobite Fossil

The listing, 500 million year old Trilobite Fossil has ended.

Trilobites are hard-shelled, segmented members of the phylum Arthropoda and the class Trilobita that appear in the fossil record for almost 300 million years—from about 540 to 251 million years ago (mya). They existed throughout almost all of the Paleozoic era, flourishing in the earlier part of it and slowly declining in the later part, finally going extinct in the Permian-Triassic extinction event about 251 mya.

The most common trilobites were about 2-7 cm (1-3.5 in) in length, but over their long history they ranged in size from 1 mm-72 cm (.04 in-28 in) and exhibited so much variation on their basic body plan that they are classified into nine (or possibly ten) orders with more than 15,000 species. The smallest species are presumed to have been part of the free floating plankton, while the more common, mid-sized species probably walked along the sea floor filtering mud to obtain food, and the larger varieties may have been swimming predators. The trilobites are considered to be the first animals to have evolved true eyes.
I purchased this trilobite from a respectable dealer in east TN. for my collection only to find out that my wife had gotten me one for my birthday so I decided to try it here. I'm not a fossil expert or anything I just think their very cool! I believe this one could be cleaned a little better but I was waiting on a day when I felt lucky before I tried but now it's up to you. Thanks for stopping by
