Archaeolithus

Archaeolithus is a genus of extinct trilobites belonging to the order Phacopida. These ancient marine arthropods lived during the Devonian period, a time when diverse marine life flourished. The fossilized remains of Archaeolithus are primarily found in marine sedimentary rocks, offering valuable insights into the paleoecology of ancient oceans.

The defining characteristics of Archaeolithus include its relatively large, convex exoskeleton. Like other trilobites, its body was divided into three lobes: a central axial lobe and two pleural lobes on either side. The head, or cephalon, typically featured prominent glabellae, which are raised areas on the dorsal surface. The thorax was segmented, allowing for some flexibility, and the tail, or pygidium, was often fused.

Fossil evidence suggests that Archaeolithus likely inhabited shallow to moderate marine environments. Its precise diet and lifestyle are inferred from its morphology and the geological context of its discovery. The distribution of Archaeolithus fossils indicates a wide geographic range during the Devonian, with specimens found in various parts of the world. The study of Archaeolithus contributes to our understanding of trilobite evolution and the broader history of life on Earth.
