Ceraurinella is an extinct genus of trilobite in the family Cheiruridae. There are about 19 described species in Ceraurinella. [1] [2]
These 19 species belong to the genus Ceraurinella:
Cambarus is a large and diverse genus of crayfish from the United States and Canada. The adults range in size from about 5 centimeters (2 in) up to approximately 15 centimeters (6 in).
Cercocarpus, commonly known as mountain mahogany, is a small genus of at least nine species of nitrogen-fixing flowering plants in the rose family, Rosaceae. They are native to the western United States and northern Mexico, where they grow in chaparral and semidesert habitats and climates, often at high altitudes. Several are found in the California chaparral and woodlands ecoregion.
Redlichia is a genus of redlichiid trilobite in the family Redlichiidae, with large to very large species. Fossils of various species are found in Lower Cambrian (Toyonian)-aged marine strata from China, Korea, Pakistan, the Himalayas, Iran, Spain, southern Siberia, and Antarctica, and from Middle Cambrian (Ordian)-aged marine strata of Australia.
Isotelus is a genus of asaphid trilobites from the middle and upper Ordovician period, fairly common in the Northeastern United States, northwest Manitoba, southwestern Quebec and southeastern Ontario. One species, Isotelus rex, is currently the world's largest trilobite ever found as a complete fossil.
Portunites is an extinct genus of decapod in the family Macropipidae. There are about 12 described species in Portunites.
Sphaerexochus is a genus of trilobite from the Middle Ordovician to Late Silurian of Asia, Australia, Europe, and North America.
Struszia is a genus of fossil trilobites from the Silurian period, erected in 1993 and named after paleontologist Desmond L. Strusz.
Aerococcus is a genus in the phylum Firmicutes (Bacteria). The genus was first identified in 1953 from samples of air and dust as a catalase-negative, gram-positive coccus that grew in small clusters. They were subsequently found in hospital environments and meat-curing brines. It has been difficult to identify as it resembles alpha-hemolytic Streptococcus on blood agar plates and is difficult to identify by biochemical means. Sequencing of 16S rRNA has become the gold standard for identification, but other techniques such as MALDI-TOF have also been useful for identifying both the genus and species.
Lepeophtheirus is a genus of sea lice. The best-known species is L. salmonis, the salmon louse. Other species include L. pectoralis, which uses flatfish as its host, particularly the European flounder, and is also the type species of the genus Lepeophtheirus.
Raphiophoridae is a family of small to average-sized trilobites that first occurred at the start of the Ordovician and became extinct at the end of the Middle Silurian.
The Cryptopidae are a family of scolopendromorph centipedes. Cryptopids are blind and possess 21 pairs of legs as adults. The genus Cryptops is the numerically largest in the family, comprising over 150 species worldwide.
Gillbeea is a genus of three species of Australasian rainforest trees from the family Cunoniaceae.
Mackenziurus is a genus of phacopid trilobites from the Silurian containing several species, including four named after members of the American punk band the Ramones.
Dendrothereua is a genus of house centipedes in the family Scutigeridae. There are at least three described species in Dendrothereua, found in the southern United States and the Neotropics.
Scolopendra cataracta is a species of centipede in the family Scolopendridae. It is the first known amphibious centipede, growing to up to 20 centimetres (7.9 in) in length.
Scolopocryptops is a genus of bark centipedes in the family Scolopocryptopidae. There are at least 20 described species in Scolopocryptops.
Strigamia is a genus of soil centipedes in the family Linotaeniidae. There are at least 50 described species in Strigamia.
Cryptochetum is a genus of scale parasite flies in the family Cryptochetidae. There are more than 30 described species in Cryptochetum.
Capitophorus is a genus of aphids in the family Aphididae. There are more than 30 described species in Capitophorus.
Diademaproetus is an extinct genus of trilobites in the family Tropidocoryphidae. There are at least four described species in Diademaproetus.
