Moroccan Trilobite Fossil - "Squishy" #1

Trilobites are extinct marine arthropods that form the class Trilobita. 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 becoming extinct in the Permian–Triassic extinction event. Trilobites have a wide range of body forms, they could be long and slender, to almost completely spherical, and some grew to over 70 cm (28 inches) in length. The three distinctive lobes of their exoskeleton are divided in three distinct regions, the cephalon (head), thorax (body) and pygidium (tail). Most trilobites were only a few centimeters long but some species grew much larger. Trilobite fossils are very common in sedimentary rocks around the world, they offer us valuable insights into past ecosystems and environments. Trilobite remains can tell us about the environment in which
