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.
Flower chafers are a group of scarab beetles, comprising the subfamily Cetoniinae. Many species are diurnal and visit flowers for pollen and nectar, or to browse on the petals. Some species also feed on fruit. The group is also called fruit and flower chafers, flower beetles and flower scarabs. There are around 4,000 species, many of them still undescribed.
Cyphaspis is a genus of small trilobite that lived from the Late Ordovician to the Late Devonian. Fossils have been found in marine strata in what is now Europe, Africa and North America. Various species had a compact body, and a large, bulbous glabellum. Many species had long spines arranged similarly to closely related genera, such as Otarian, Otarionella, Chamaeleoaspis, and Namuropyge.
Arduennella is a Devonian homalonotid genus of trilobite in the order Phacopida, which existed in what is now Belgium, Germany, Morocco and Romania. It was described by Wenndorf in 1990, and the type species is Arduennella maillieuxi, which was originally described as Homalonotus maillieuxi by Asselberghs in 1923.
Asteropyge is an extinct genus of trilobite. It lived from the end of the Lower Devonian into the Middle Devonian, in what are today France, and Germany.
Geesops is an extinct genus of trilobites in the family Phacopidae. There are about five described species in Geesops.
Ceratarges was a genus of lichid Trilobite from the Middle Devonian. It lived in what is now western Europe and Morocco.
Städtische Galerie im Park Viersen is the municipal art gallery of Viersen in North Rhine-Westphalia, Germany. It has a collection of graphic reproductions. The gallery is located in an old town house, surrounded by a park with huge old trees housing the Viersen sculpture collection.
Lejopyge laevigata is a species of agnostid trilobite belonging to the genus Lejopyge. It existed during the Guzhangian to the Paibian Age of the Cambrian. It has a cosmopolitan distribution and is an important index fossil in biostratigraphy.
The Illaenidae are a family of trilobites in the order Corynexochida. 223 currently accepted species in 24 genera are known from the Ordovician. Some scholars include the Panderiidae in the Illaenidae, but this is not generally supported.
Hollardops is a genus of trilobite in the order Phacopida that lived during the Devonian. Their fossils are found in the upper Emsian of western Europe and in the lower Emsian to lowermost Eifelian of North Africa. The type species, Asteropyge mesocristata, was described from Algeria by Le Maître in 1952. The genus Hollardops was erected by Morzadec in 1997. In the same year, Lieberman & Kloc erected Modellops and Philipsmithiana but those genera are regarded as subjective synonyms of Hollardops. The 10-segmented thoracic condition of Hollardops is a rare feature among acastid trilobites that almost always have 11 thorax segments. Van Viersen & Kloc (2022) revisited Hollardops and described a number of new species from Morocco. They also regarded Pennarbedops Bignon & Crônier, 2013 as a synonym of Hollardops. Van Viersen & Kloc construed Hollardops as a scavenger or predator with well-developed eyes, that used its shovel-like cephalon to plough the top layers of the sediment in search of food. Hollardops had small pits horizontally along the fringe of the exoskeleton; these are believed to have housed setae that allowed the trilobite to closely monitor its surroundings.
Gerastos is a genus of proetid trilobite in the family Proetidae that lived between the Pragian and Eifelian of the Lower-Middle Devonian, spanning approximately 21 million years.
Magreanops is a phacopid trilobite in the family Phacopidae. The type species is Magreanops renateae and the genus also includes Magreanops monachus, both described from the Frasnian-aged Bovesse Formation. and Moulin Liénaux Formations in Belgium during 2018.

2020 in arthropod palentology is a list of new arthropod fossil taxa, including arachnids, crustaceans, insects, trilobites, and other arthropods that were announced or described, as well as other significant arthropod paleontological discoveries and events which occurred in 2020.
The Vireux-Molhain national nature reserve (RNN104) is a national nature reserve of geological and paleontological interest. It is located in the Pointe de Givet, department of Ardennes, on the border between France and Belgium. It covers an area of 1.82 ha. The site is known as Customs Wall as it is near an old customs post. This outcrop of Middle Devonian shale is notable for the quantity and good state of preservation of its fossils. Trilobites are well-represented.
Diademaproetus is an extinct genus of trilobites in the family Tropidocoryphidae. There are at least four described species in Diademaproetus.
Hans Herbert Jöris was a German conductor and academic teacher who worked at the Theater Dortmund and the Staatsoper Hannover and taught at the Hochschule für Musik, Theater und Medien Hannover.
