The fossil is of Bohemolichas incola, one of more than 20,000 trilobite species that existed during their 270-million-year reign on Earth.

When you examine a fossilized trilobite, you could effectively study three distinctive sections: The cephalon is situated in the front of the creature and contains the eyes, various sutures, the antennae and the glabella. The thorax is located in the center of the trilobite. The pygidium is situated to the rear of the creature.

Because trilobites had wide diversity and an easily fossilized exoskeleton an extensive fossil record was left behind, with some 17,000 known species spanning Paleozoic time. The study of these fossils has facilitated important contributions to biostratigraphy, paleontology, evolutionary biology and plate tectonics.

Jul 6, 2023 · Trilobite fossils are typically formed through the process of fossilization, where the remains of a trilobite are buried in sediment and over time, the organic material is replaced by minerals.

Oklahoma Through Time Oklahoma’s rich fossil record ... grid in illustrator May 3, 2021 · Trilobites were some of the first complex animals to appear in the fossil record and were extremely successful during their time. They existed in the oceans for more than 300 million years, and 20,000 different species have been found. Trilobites eventually went extinct in the great Permian mass extinction 252 million years ago. Trilobites periodically shed their exoskeleton to accommodate growth; trilobite fossils sometimes preserve so-called moult configurations that show various stages in the release of the old exoskeleton and escape of the then soft-bodied animal. Moulting is another diagnostic feature of the arthropods. Abstract. Trilobites offer one of the best fossil records of any arthropod group. This is due to a number of factors, most notably the combination of (1) having inhabited areas where organisms are more likely to be buried and ultimately fossilized; and (2) having had a highly biomineralized exoskeleton more likely to survive the stresses of fossilization.
