Olenothus

Olenothus is an extinct genus of trilobite belonging to the family Olenidae. These trilobites lived during the Cambrian period, specifically the Late Cambrian. Fossils of Olenothus have been found in various locations, including North America and Scandinavia.

Olenothus trilobites are characterized by their relatively flat exoskeletons, a semi-circular cephalon (head shield), and a pygidium (tail shield) that is generally smaller than the cephalon. Like other olenid trilobites, they are believed to have been benthic organisms, living on or near the seafloor. Their feeding habits are not fully understood, but it is likely they were detritivores or scavengers.

The taxonomy and classification of Olenidae, including Olenothus, have been subject to revision and debate within the paleontological community. Distinguishing features, such as the shape and segmentation of the thorax and pygidium, are used to differentiate species within the genus.

The study of Olenothus, along with other olenid trilobites, provides valuable insights into the paleogeography and paleoecology of the Late Cambrian period. Their distribution patterns can help reconstruct ancient continental configurations and understand the environmental conditions of the time.
