While it may look like some kind of science fiction cockroach, this papercraft is of an actual animal that lived on Earth millions of years ago. Trilobites were a group of marine animals that according to scientists became extinct around 250 million years ago. This paper model trilobite was originally created by the Australian Geological Survey Organisation to teach children about fossils. The one page, hand drawn template for the trilobite may be downloaded from the Houston Gem & Mineral Society website here.
