Elektroepyris is an extinct genus of wasp within the family Bethylidae containing a single species, Elektroepyris magnificus. [1] It lived in the lower Eocene, with the type locality being from the Oise amber, Le Quesnoy located in France. [2] [3]
Galeocerdo is a genus of ground shark. Only a single species, G. cuvier, the tiger shark is extant. The earliest fossils date back to the early Eocene epoch, (Ypresian), around 56–47.8 Million years ago. While historically considered a member of the requiem shark family Carcharhinidae, it is currently considered to be the only member of the family Galeocerdonidae. While this genus was historically considered diverse, including 21 extinct species, morphometric analysis conducted in 2021 suggested that the diversity of the genus included only 5 extinct species much lower than previously assumed. The oldest fossils of the extant G. cuvier date to the middle Miocene.
Scutigera is a centipede genus in the scutigeromorph family Scutigeridae, a group of centipedes with long limbs and true compound eyes. It compose of more than 30 species, including the most common and well-studied Scutigera coleoptrata.
Carcharhinus is the type genus of the family Carcharhinidae, the requiem sharks. One of 12 genera in its family, it contains over half of the species therein. It contains 35 extant and eight extinct species to date, with likely more species yet to be described.
Tanyderidae, sometimes called primitive crane flies, are long, thin, delicate flies with spotted wings, superficially similar in appearance to some Tipulidae, Trichoceridae, and Ptychopteridae. Most species are restricted in distribution. They are found in many parts of the world, including North America, South America, Africa, Australia, New Zealand, and various islands in the Pacific Ocean. Adults are usually found hanging from vegetation near streams. Larvae are found either in sandy stream margins or in wet, rotten wood. Fossil species are known.
The Mymarommatidae, sometimes referred to as false fairy wasps, are a very small family of microscopic parasitic wasps. Only about half of the known species are living taxa, but they are found worldwide.
Carcharias is a genus of mackerel sharks belonging to the family Odontaspididae. Once bearing many prehistoric species, all have gone extinct with the exception of the critically endangered sand tiger shark.
Epihippus is an extinct genus of the modern horse family Equidae that lived in the Eocene, from 46 to 38 million years ago.
The Nevrorthidae are a small family of lacewings in the order Neuroptera. There are 19 extant species in four genera, with a geographically disjunct distribution: Nevrorthus, comprising 5 species with scattered distributions around the Mediterranean; Austroneurorthus, with two species known from southeastern Australia; Nipponeurorthus, comprising 11 species known from China and Japan; and Sinoneurorthus, known from a single species described from Yunnan Province, China. They are traditionally placed in the Osmyloidea, alongside Osmylidae and the spongillaflies (Sisyridae), but some research has considered them to be the sister group to the rest of Neuroptera. The larvae have unique straight jaws that are curved at the tips, and live as unspecialised predators in the sandy bottom sediments of clear, fast flowing mountain rivers and streams. They pupate underwater on the underside of stones. The adults are likely predators or feed on honeydew and other sugar-rich fluids.
Scaumenacia is an extinct genus of lungfish. It lived around the Devonian in North America alongside another prehistoric lungfish: Fleurantia. It lived from approximately 384 to 376 millions of years ago.
Baltocteniza is an extinct monotypic genus of spider in the family Ctenizidae. At present, it contains the single species Baltocteniza kulickae. The genus is solely known from the Early Eocene Baltic amber deposits in the Baltic Sea region of Europe.
Baenidae is an extinct family of paracryptodiran turtles known from the Early Cretaceous to Eocene of North America. While during the Early Cretaceous they are found across North America, during the Late Cretaceous they are only found in Laramidia, having disappeared from Appalachia. The majority of lineages survived the K-Pg Extinction, but the family was extinct by the latest Eocene. The name of the type genus, Baena, appears to be of Native American origin. They are primarily found in freshwater deposits, and are considered to be aquatic, with a largely generalist habit.
Leptadapis is a genus of adapiform primate that lived in Europe during the middle Eocene. Fossils of the genus have been found in the Escanilla Formation of Spain and Egerkingen in Switzerland.
Micromomyidae (Micromomids) is a family of extinct plesiadapiform mammals that include some of the earliest known primates. The family includes five genera that lived from the Paleocene epoch into the early Eocene epoch.
Wyonycteris is a genus of small mammals that existed in the late Paleocene and early Eocene epochs. The type species is Wyonycteris chalix, which lived in Wyoming during the Clarkforkian North American Land Mammal Age of the Paleocene and was originally proposed to be an early form of insectivorous bat. Later re-examination of the material has put this alliance in doubt, and the genus has instead been proposed as belonging to the subfamily Placentidentinae, within the family Nyctitheriidae. Similar fossil material of the same time period found in Europe was later discovered and described as new species, Wyonycteris richardi.
Palaeophasianus is an extinct genus of flightless Geranoididae birds that lived in North America during the Eocene period. Robert Wilson Shufeldt classified Palaeophasianus as a galliform when he described it in 1913. However it was transferred to Cracidae in 1964 by Pierce Brodkorb, while Joel Cracraft in 1968 placed it in Gruiformes.
Helohyidae were a group of artiodactyl mammals. They were most prominent in the mid-to-upper Eocene.
Simpsonotus is an extinct genus of notoungulate mammals in the family Henricosborniidae from the Middle to Late Paleocene of South America. Fossils of the genus have been found in the Mealla Formation, a fluvial and lacustrine sedimentary unit of the Salta Basin in northwestern Argentina. The genus name honors paleontologist George Gaylord Simpson.
Cupes manifestus is an extinct species of reticulated beetle in the family Cupedidae and the genus Cupes. It is known from Selandian crater lake diatomite in the Menat Formation of France.
Trichonta is a genus of flies belonging to the family Mycetophilidae.
Eurheloderma is an extinct genus of heloderm lizard known from the late Eocene of France.
