For reference, U.S. penny in picture measures 19mm (3/4") in diameter. Trilobites were among the early arthropods, a phylum of hard-shelled creatures with multiple body segments and jointed legs (although the legs, antennae and other finer structures of trilobites only rarely are preserved). They constitute an extinct class of arthropods, the Trilobita, made up of ten orders, over 150 families, about 5,000 genera, and over 20,000 described species. New species of trilobites are unearthed and described every year. This makes trilobites the single most diverse class of extinct organisms, and within the generalized body plan of trilobites there was a great deal of diversity of size and form. The smallest known trilobite species is under a millimeter long, while the largest include species from 30 to over 70 cm in length (roughly a foot to over two feet long!). With such a diversity of species and sizes, speculations on the ecology of trilobites includes planktonic, swimming, and crawling forms, and we can presume they filled a varied set of trophic (feeding) niches, although perhaps mostly as detritivores, predators, or scavengers. Most trilobites are about an inch long, and part of their appeal is that you can hold and examine an entire fossil animal and turn it about in your hand. Because trilobites are so diverse in the fossil record, are found on all continents, and while individual species occupy distinct and narrow stratigraphic ranges, in total they cover nearly the entire duration of the Paleozoic Era, their fossils play a major role in determining the order and age of global geological strata.
