Cimbrophlebia is an extinct genus of Mecoptera which existed from the Jurassic to the Eocene period. [1]
The genus Cimbrophlebia contains the species: [1]
Nymphidae, sometimes called split-footed lacewings, are a family of winged insects of the order Neuroptera. There are 35 extant species native to Australia and New Guinea.
Euphaeidae, sometimes incorrectly named Epallagidae and commonly called gossamerwings, is a family of damselflies in the odonate superfamily Calopterygoidea. The family is small, consisting of around 78 species living species in nine genera occurring in the Palearctic, Australasia, and Asia. The family contains two subfamilies, Euphaeinae, encompassing all the living species and a single fossil genus, and the extinct Eodichromatinae, encompassing fossil genera from the Eocene to late Oligocene. Euphaeid species are large and mostly metallic-coloured, looking similar to species of damselflies in the family Calopterygidae.
Tilia johnsoni is an extinct species of flowering plant in the family Malvaceae that, as a member of the genus Tilia, is related to modern lindens. The species is known from fossil leaves found in the early Eocene deposits of northern Washington state, United States and a similar aged formation in British Columbia, Canada.
Allorapisma is an extinct genus of lacewing in the moth lacewings family Ithonidae. The genus is solely known from two Eocene fossils found in North America. At the time of description the genus was composed of a single species, Allorapisma chuorum.
Dillhoffia is an extinct monotypic genus of flowering plant with a single species, Dillhoffia cachensis known from Ypresian age Eocene fossils found in British Columbia, Canada, and Washington, USA. The genus and species were described from fifteen specimens found in an unnamed formation belonging to the Kamloops group shales; and two specimens from the Klondike Mountain Formation. The unnamed formation outcrops at the McAbee Fossil Beds near Cache Creek, BC, which is designated the type locality while the two U.S. specimens were recovered from the Tom Thumb Tuff member of the Klondike Mountain Formation in Republic, Washington. It is of interest to note that of the Okanagan highlands fossil sites Dillhoffia is only known from two locations, and is absent or has not been identified from the others.
Ithonidae, commonly called moth lacewings and giant lacewings, is a small family of winged insects of the insect order Neuroptera. The family contains a total of ten living genera, and over a dozen extinct genera described from fossils. The modern Ithonids have a notably disjunct distribution, while the extinct genera had a more global range. The family is considered one of the most primitive living neuropteran families. The family has been expanded twice, first to include the genus Rapisma, formerly placed in the monotypic family Rapismatidae, and then in 2010 to include the genera that had been placed into the family Polystoechotidae. Both Rapismatidae and Polystoechotidae have been shown to nest into Ithonidae sensu lato. The larvae of ithonids are grub-like, subterranean and likely phytophagous.
Sassafras hesperia is an extinct species of flowering plant in the family Lauraceae.
Neoephemera antiqua is an extinct species of square-gill mayfly in the family Neoephemeridae that is known from early Eocene, Ypresian stage, lake deposits near the small community of Republic in Ferry County, Washington, USA.
The Klondike Mountain Formation is an Early Eocene (Ypresian) geological formation located in the northeast central area of Washington state. The formation is comprised of volcanic rocks in the upper unit and volcanic plus lacustrine (lakebed) sedimentation in the lower unit. the formation is named for the type location designated in 1962, Klondike Mountain northeast of Republic, Washington. The formation is a lagerstätte with exceptionally well-preserved plant and insect fossils has been found, along with fossil epithermal hot springs.
Langeria is an extinct genus of flowering plants in the family Platanaceae containing the solitary species Langeria magnifica. Langeria is known from fossil leaves found in the early Eocene deposits of northern Washington state, United States and similar aged formations in British Columbia, Canada.
Eoprephasma is an extinct genus of stick insect in the susumaniid subfamily Susumaniinae known from a group of Eocene fossils found in North America. When first described there was a single named species, Eoprephasma hichensi.
Eorpidae is a small family of extinct insects in the scorpionfly order, Mecoptera, which contains a single genus, Eorpa. Three Eocene age species found in Western North America have been placed into the genus: E. elverumi, E. jurgeni, and E. ypsipeda.
Pentacentron is an extinct genus of flowering plant in the family Trochodendraceae, consisting of the single species Pentacentron sternhartae. The genus is known from fossil fruits found in the early Eocene deposits of northern Washington state, United States. P. sternhartae are possibly the fruits belonging to the extinct trochodendraceous leaves Tetracentron hopkinsii.
Paraconcavistylon is an extinct genus of flowering plant in the family Trochodendraceae comprises a single species, Paraconcavistylon wehrii. The genus is known from fossil fruits and leaves found in the early Eocene deposits of northern Washington state, United States, and southern British Columbia, Canada. The species was initially described as a member of the related extinct genus Concavistylon as "Concavistylon" wehrii, but subsequently moved to the new genus Paraconcavistylon in 2020 after additional study.
Pseudolarix wehrii is an extinct species of golden larch in the pine family (Pinaceae). The species is known from early Eocene fossils of northern Washington state, United States, and southern British Columbia, Canada, along with late Eocene mummified fossils found in the Qikiqtaaluk Region, Nunavut, Canada.
Comptonia columbiana is an extinct species of sweet fern in the flowering plant family Myricaceae. The species is known from fossil leaves found in the early Eocene deposits of central to southern British Columbia, Canada, plus northern Washington state, United States, and, tentatively, the late Eocene of Southern Idaho and Earliest Oligocene of Oregon, United States.
Klondikia is an extinct hymenopteran genus in the ant family Formicidae with a single described species Klondikia whiteae. The species is solely known from the Early Eocene sediments exposed in northeast Washington state, United States. The genus is currently not placed into any ant subfamily, being treated as incertae sedis.
The paleofauna of the Eocene Okanagan Highlands is comprised of Early Eocene arthropods, vertebrates, plus rare nematodes and molluscs found in geological formations of the northwestern North American Eocene Okanagan Highlands. The highlands lake bed series' as a whole are considered one of the great Canadian Lagerstätten. The paleofauna represents that of a late Ypresian upland temperate ecosystem immediately after the Paleocene-Eocene thermal maximum, and before the increased cooling of the middle and late Eocene to Oligocene. The fossiliferous deposits of the region were noted as early as 1873, with small amounts of systematic work happening in the 1880-90s on British Columbian sites, and 1920-30s for Washington sites. Focus and more detailed descriptive work on the Okanagan Highlands site started in the last 1970's. Most of the highlands sites are preserved as compression-impression fossils in "shales", but also includes a rare permineralized biota and an amber biota.
The Paleobiota of the Klondike Mountain Formation comprises a diverse suite of Early Eocene plants and animals recovered from North Central Washington State. The formation outcrops in locations across the north western area of Ferry County, with major sites in Republic, north west of Curlew Lake, and on the Toroda Creek area. The formation is the southern most of the Eocene Okanagan Highlands, sharing much of the paleoflora and paleofauna with site across Central and southern British Columbia.
