Trilobites
  Trilobites are one of the most universally recognized fossils.  Trilobites roamed the sea floors from
520 million years to 250 million ago.  Trilobites were a wonderfully diverse group of arthropods that
came in various sizes from less than an inch to several feet in length.  Some of them can have a very
exotic look to them.
