Tritemnodon was a genus of hyaeanodontid which lived 50.5-46.2 million years ago. Fossils of Tritemnodon agilis have been found in Utah and Wyoming, and it was the size of a wolf.
Gracilocyon is an extinct genus of miacid carnivoran which existed in United States, Belgium and in the United Kingdom during the earliest Eocene. It was first named by Thierry Smith and Richard Smith in 2010 and the type species is Gracilocyon winkleri.
Ordralfabetix is an extinct genus of planthoppers in the family Lophopidae and containing the single species Ordralfabetix sirophatanis. The species is known only from the Early Eocene, Ypresian stage Oise amber from the Quesnoy locality, Oise Department, France.
Pliolophus is an extinct equid that lived in the Early Eocene of Britain.
Indohyaenodon is a genus of extinct hyaenodont mammals from family Indohyaenodontidae, that lived during the early Eocene in India.
The Oulad Abdoun Basin is a phosphate sedimentary basin located in Morocco, near the city of Khouribga. It is the largest in Morocco, comprising 44% of Morocco's phosphate reserves, and at least 26.8 billion tons of phosphate. It is also known as an important site for vertebrate fossils, with deposits ranging from the Late Cretaceous (Cenomanian-Turonian) to the Eocene epoch (Ypresian), a period of about 25 million years.
The Wasatch Formation (Tw) is an extensive highly fossiliferous geologic formation stretching across several basins in Idaho, Montana Wyoming, Utah and western Colorado. It preserves fossils dating back to the Early Eocene period. The formation defines the Wasatchian or Lostcabinian, a period of time used within the NALMA classification, but the formation ranges in age from the Clarkforkian to Bridgerian.
The Indian Meadows Formation is a Wasatchian geologic formation in Wyoming. It preserves fossils dating back to the Ypresian stage of the Eocene period.
The Margaret Formation is a geologic formation of the Eureka Sound Group in the Sverdrup Basin in Northwest Territories and Nunavut, Canada. The unit belonging to the Eureka Sound Group which crops out at Ellesmere Island preserves fossils dating back to the Early Eocene period, or Wasatchian in the NALMA classification.
The Conglomérat de Cernay is a geologic formation in Champagne-Ardenne, northern France. It preserves fossils dating back to the Thanetian stage of the Paleocene period. The lizard Cernaycerta and placental mammal Bustylus cernaysi are named after the formation.
The Lignites de Soissonais is a geologic formation in the Var, Marne departments of France. It preserves fossils dating back to the Ypresian stage of the Eocene period.
The Quercy Phosphorites Formation is a geologic formation and Lagerstätte in Occitanie, southern France. It preserves fossils dating back to the Paleogene period, or MP16 to MP28 zones of the European land mammal age classification, ranging from approximately 38 to 25 Ma.
Lahimia ("carnivore") is a genus of extinct hyaenodont mammals, known from the Selandian stage of Africa.
Galecyon is a genus of hyaenodont that lived during the early Eocene in Europe and North America.
The Black Crow Limestone is an Early Eocene geologic formation in the Sperrgebiet, ǁKaras Region of southwestern Namibia. The limestones of the approximately 10 metres (33 ft) thin formation were deposited in a lacustrine to paludal environment. The formation provides many fossil mammals and amphibians, reptiles, fresh water snails and fish.
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.
Electrentomidae is an extinct family of barklice, booklice, and parasitic lice in the order Psocodea. There are about six genera and seven described species in Electrentomidae. The family was synonymsed with the extant family Manicapsocidae in 2003 without discussion, with a prior proposal in 1972, but Azar et al, 2017, stated that "we consider herein [Electrentomidae and Manicapsocidae] apart, because a cladistic phylogenetic analysis is needed prior to taking such important decision for these groups."
The Silveirinha Formation is an Early Eocene geologic formation of the Mondego Basin in the Região Centro of central-western Portugal. The sandstones, siltstones and conglomerates were deposited in an alluvial environment.
The Alai Beds is an Early Eocene geologic formation in the Osh Region of southwestern Kyrgyzstan. The formation has provided many fossils of mammals, lizards, turtles and snakes.
Manicapsocidae is a family of Psocodea. It contains 8 extant species in 4 genera, with most of the species being found in the Neotropics, with one species in the Afrotropics. The extinct family Electrentomidae has been suggested to be a synonym of this family, though this has been considered premature by other scholars in the absence of cladistic analysis. Confirmed fossil species of the family are nearly as numerous as living ones, extending back to the Mid-Cretaceous.
