Phacopidae is a family of phacopid trilobites that ranges from the Lower Ordovician to the Upper Devonian, with representatives in all paleocontinents.
Phacops is a genus of trilobites in the order Phacopida, family Phacopidae, that lived in Europe, northwestern Africa, North and South America and China from the Late Ordovician until the very end of the Devonian, with a broader time range described from the Late Ordovician. It was a rounded animal, with a globose head and large eyes, and probably fed on detritus. Phacops is often found rolled up ("volvation"), a biological defense mechanism that is widespread among smaller trilobites but further perfected in this genus.
Trimerocephalus is a genus of eyeless trilobites from the order Phacopida, family Phacopidae. It lived during the final stage of the Devonian, the Famennian, and became extinct at the end of this stage, together with all other trilobites with the exception of some Proetida. It can be found in Australia, the Czech Republic, France, Germany, Iran, Kazakhstan, Morocco, Poland, the Russian Federation (Urals), Spain, and the United Kingdom (England).

It was described by Harrington in 1957, and the type species is Hintzeia aemula, which was originally described under the genus Protopliomerops by Hintze in 1953. Harrington also moved two other Protopliomerops species, P. celsaora and P. firmimarginis, under Hintzeia. The generic name is derived from that of the type species' author. The type locality was the Fillmore Formation in Utah.

Serrodiscus Richter and Richter 1941. is a genus of Eodiscinid trilobite belonging to the family Weymouthiidae Kobayashi T. (1943), Order Agnostida. It lived during the late Lower Cambrian, with remains found in Canada, China (Gansu), The United Kingdom (England), Germany (Silesia), Poland, the Russian Federation, and the United States. It is named for the spines on the ventral side of the pygidium, which give it a serrated impression.
Miraspis mira is a spinose species of odontopleurid trilobite in the family Odontopleuridae. Fossils of M. mira are known from the Wenlock-aged Liteň Formation in Loděnice, in Bohemia, Czech Republic, originally described by Joachim Barrande, in 1846, as "Odontopleura mira." In 1917, Richter and Richter split "O. mira" off into its own genus, Miraspis.
