Profile Harpes neograciles

(=Helioharpes; Reticuloharpes) trilobit

Habitat

Trilobites were generally inhabitants of the seabed (benthos). Most fossils are from coastal (littoral) habitats, some also from mid-sea depths (shelf areas). Some lived in oxygen-poor, muddy sediments. Most trilobites probably fed as predators and/or scavengers. This is probably also the original way of life. The morphology of the genus Harpes shows evidence of a lifestyle as detritus/sediment eaters or filter feeders.

Geological era

Upper Devonian, Frasnium

Sources

Fossil finds are known from the Lower Harz, northern Sauerland, Kellerwald, Lahn-Dill area, Thuringia, Czechia, southern France

Further Informations

Harpida is one of the nine orders of the extinct arthropod class Trilobita. The first harpetid trilobites appear in the Upper Cambrian, and the last species die out at the end of the Devonian period.

Harpetid trilobites are characterized among trilobites by bearing a comparatively large, semicircular brim around the cephalon (head) which is often perforated by small pores. This brim is thought to serve as a filter-feeding apparatus. The brim stretches backward on either side of the cephalon (head) and typically has a pronounced suture along the outside.

The compound eyes are typically reduced to small tubercles, though they have strong ridges stretching to the glabella (central region of the cephalon). They also typically have 12 or more thoracic segments. The pygidia are usually small.
