Odontopleuridae

Odontopleuridae is a family of odontopleurid trilobites found in marine strata throughout the world. Odontopleurids of Odontopleuridae first appear in Late Cambrian-aged marine strata, and the last genera perish by the end of the Frasnian stage during the Late Devonian. The members of Odontopleuridae are famous for their spinose appearance, having long, often numerous spines along the edges of their exoskeletons, and derived from ends of segments or tubercle ornaments.
