Trilobite, meaning "three lobes", occupied different levels of the food web including predator, scavenger, and prey. Trilobites molted their exoskeleton much like lobsters of today and are one of the first animals known to have the sense of vision. The Trilobite comes with a Riker-Style box. Boxes are made of compressed hardboard with a textured surface coating, which include a clear glass window for showing off your fossil as well as a label to identify it. Made by artisans in the U.S.A, it is cast in super-durable resin. The Trilobite measures approximately 5 1/2-inches x 3-inches x 1 1/2-inches, while the case measures 6 1/4-inches x 8 1/4-inches x 2-inches.
