Trilobite phylum
Trilobites are an extinct group of arthropods, distinguished by the following characters: a body built from a cephalon, thorax, and pygidium a body divided into three lobes, running from head to tail one pair of antennae The last trilobites went extinct about 245 million years ago, but they are well represented by the fossil record. Trilobites were among the world's first arthropods, a phylum of hard-shelled creatures with multiple body segments and jointed legs (although the legs ...The state of Michigan used to be covered by a warm, shallow sea and was later an unforgiving glacial landscape. Common fossils found here are trilobites, corals, sea lilies, and even mammoth teeth. In Michigan, we have very weathered rocks along our shoreline. This can cause the fossils to be cut in obscure ways, making their appearance strange.

Trilobozoa (meaning "three-lobed ani Trilobites (Phylum Arthropoda, Class Trilobita) Trilobites are extinct marine arthropods that were important components of marine communities during much of the Paleozoic Era. Trilobites had a hard, calcified, and segmented exoskeleton and are often well-preserved as fossils. Although parts of their exoskeleton, such as the legs and antennae ...The trilobites may have gone extinct (along with 95% of marine species) during the mass extinction at the end of the Permian period, but that doesn’t mean that they were a failure. On the contrary, the trilobites survived for more than 250 million years (longer than the dinosaurs), and dominated seafloor ecosystems for much of this time.

Narrow with a long thorax, have a small pygidium, and a plain looking cephalon. The cephalon has a series of glabellar furrows (parallel ridges running across the glabella).
