Real Trilobite Fossil: Flexicalymene Trilobites or “mud bugs” found in Morocco. These fossils are about 350 million years old and are great for new collectors.
Trilobites form one of the earliest known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago), and they flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Devonian, all trilobite orders except the Proetids died out. Trilobites finally disappeared in the mass extinction at the end of the Permian about 250 million years ago. The trilobites were among the most successful of all early animals, roaming the oceans for over 270 million years.
These are real specimens, so each specimen will be unique in appearance, shape, and color.
