Radiaspis is a genus of trilobite that lived from Late Ordovician through the Silurian to the mid-Devonian period. Fossils of Radiaspis have been found in present-day Europe, Australia, North Africa, and North America.
Fossil range
Radiaspis is a "generally rare" species found from the Ordovician to Devonian periods. Radiaspis fossils have been discovered in Australia, western Europe, North America, and Morocco.[1] Some of the earliest Radiaspis fossils – Radiaspis tuberata from Aragon – date from the early Late Ordovician, around 445 million years ago. Some of the youngest fossils date to around 386 million years ago, in the lower Givetian;[2] it is believed that the genus Radiaspis and several other trilobite genera became extinct at the time of the Taghanic event.[3]
