Selenopeltis

Selenopeltis is an extinct genus of trilobite in the order Lichida, family Odontopleuridae.

Species in the genus Selenopeltis can reach a length of 115–160 millimetres (4.5–6.3 in) and a width of 115–130 millimetres (4.5–5.1 in). These trilobites show long pleural spines and were a low-level epifauna, fast-moving and detritivore. They lived in the Ordovician period, from the Lower Arenig stage age until the Ashgillian age (478.6-443.7 million years ago).
