Trilobites were marine arthropods that lived on earth for 300 million years. They were generally small, had a segmented exoskeleton, and crawled around on the bottom of the oceans floor. Most Trilobites had eyes or eye-like structures that were positioned atop their heads and ate detritus that had settled into the sediment (a little like a living Roomba).
Because Trilobites were around for so long and were so prolific, their fossils are found all over the world. The smallest species were mere millimeters long, and the largest was almost 30 inches long. They often died in odd positions, similar to a bug, which you can see demonstrated here.
