Description
Trilobites are hard-shelled, segmented orthopods that existed over 300 million years ago in the Earth's ancient seas. Trilobites are second in fame only to the dinosaurs. They range in size from the smallest being less than 1cm and the largest more than 70cm long. They lived in marine waters but not all trilobites could swim, some trilobites actually burrowed under the seas or crawled on the muddy sea floors.
These Trilobite fossils average 3/4" in size. Some fossils are partials. Size and variety will vary from sample to sample.
