Wessiea
''Wessiea'' is an extinct morphogenus of fern not placed in a specific family. ''Wessiea'' is known from Late Cretaceous and Middle Miocene age fossils found in Central Washington USA and Southern Alberta Canada. Two species are described in the morphogenus, ''W. oroszii'' and the type species ''W. yakimaensis''. History and classification The genus was first described from specimens of silicified rhizomes and frond bases in blocks of chert. The chert was recovered from the "Ho ho" site, one of the "county line hole" fossil localities north of Interstate 82 in Yakima County, Washington. The "Ho ho" site works strata which is part of the Museum Flow Package within the interbeds of the Sentinel Bluffs Unit of the central Columbia Plateau N2 Grande Ronde Basalt, Columbia River Basalt Group. The Museum Flow Package interbeds, designated the type locality, are dated to the middle Miocene and are approximately 15.6 million years old. The holotype specimen, rhizomes and fronds #1–3 ...

Nogodinidae
Nogodinidae is a family of planthoppers. They have membranous wings with delicate venation and can be confused with members of other Fulgoroid families such as the Issidae and Tropiduchidae Tropiduchidae is a family of planthoppers in the order Hemiptera. There are at least 160 genera and 600 described species In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as .... Some authors treat it as a subfamily of the Issidae. Some of their key features are a frons ("face") that is longer than wide and a reticulate wing venation. They are less than 2 cm long. The antenna arises well below the eye, has the base clubbed and flagellum unsegmented. The lateral ocelli (simple eyes) are outside the margins of the face. The face has carinae (or keels) on the edge. On the hind leg, the second tarsal segment has an apical spine arising from it. The tibia of the hind leg also has spines towards the tip. An important f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tainosia
''Tainosia'' is an extinct monotypic genus of planthopper in the Nogodinidae subfamily Nogodininae and at present, it contains the single species ''Tainosia quisqueyae''. The genus is solely known from the early Miocene, Burdigalian stage, Dominican amber deposits on the island of Hispaniola. History and classification ''Tainosia quisqueyae'' is known only from one fossil, the holotype, number "BMNH Pal. PI II 62". It is a single individual of indeterminate sex preserved in a clear orange amber specimen. The specimen is mostly complete, though the right tegmen torn, and the hind legs are partly destroyed. The insect was entombed while in resting posture, with both the hemelytra and hindwings mostly closed. The amber is currently residing in the Department of Palaeontology paleoentomology collections of the Natural History Museum in London, England. ''T. quisqueyae'' was first studied by Jacek Szwedo and Adam Stroiński, with their 2001 type description being published in the ...

Ithonidae
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 (plant feeding). Description and ecology Ithonidae are typically medium to large-sized neuropterans. P. S. Welch conducted research in 1914 on "Polystoechotidae" larvae r ...

Fur Formation
The Fur Formation is a marine geological formation of Ypresian (Lower Eocene Epoch, c. 56.0-54.5 Ma) age which crops out in the Limfjord region of Denmark from Silstrup via Mors and Fur to Ertebølle, and can be seen in many cliffs and quarries in the area. The Diatomite Cliffs (''moler'' in Danish) is on the Danish list of tentative candidates for World Heritage and may become a world Heritage site. Geology The Fur Formation is a unit of diatomitic sediment approximately 60 meters thick consisting of diatoms and clay minerals with up to 180 layers of volcanic ash. In Danish literature the formation has informally been referred to as the ''moler'' (''Ler'' means clay). The diatomite comprises 2/3 opal tests of diatoms and 1/3 clay, interbedded with layers of volcanic ash and a few limestone horizons (‘cementstones’), and has exceptionally complete fossil preservation. It is known for its abundant fossil fish, insects, reptiles, birds and plants. The Fur Formation was deposite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeopsychops
''Palaeopsychops'' is an extinct genus of lacewing in the moth lacewings family Ithonidae. The genus is known from Early Eocene fossils found in Europe, and North America and is composed of ten species. The ten species can be informally separated into two species groups based on veination of the forewings, the "European" and "North American" groups. When first described, the genus was placed in the family Psychopsidae, but later was moved to Polystoechotidae, which itself is now considered a subgroup of the moth lacewings. Distribution & age The European species of ''Palaeopsychops'' are all known from the Early Eocene Fur Formation along the western Limfjord coast of Denmark. Most of the thick formation is diatomites with an interspersed sequence of approximately 179 ash layers. Argon–argon radiometric dating of ash layer "+19", which is slightly lower in the strata then the "insect beds", has determined a age. ''Palaeopsychops'' species have been recovered from three loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acropyga Glaesaria SMFBE457B2 01
''Acropyga'' is a genus of small formicine ants. Some species can be indirect pests. '' A. acutiventris'', which is found from India to Australia, tends subterranean, root-feeding mealybugs of the species '' Xenococcus annandalei''. Living, gravid females are carried in the jaws of ''A. acutiventris'' queens during their nuptial flight, to establish the symbiotic association in founding colonies. Other ''Acropyga'' species have relationships with different species of mealybugs, and it could be a trait common to the whole genus. Description ''Acropyga'' are smaller than , with a compact, stocky body. They have antennae with 10 or 11 segments (including the scape), short palps and reduced eyes with four to 30 individual ommatidia. In some species, the eyes are completely absent. Distribution ''Acropyga'' is found in the Americas, southern Africa, India to Southeast Asia and Australia. ''A. paleartica'' is known only from Greece. Fossil specimens of ''Acropyga '' have been re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coccoidea
Scale insects are small insects of the Order (biology), order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as Honeydew (secretion), honeydew on which sooty mold tends to grow. The insects often have a Mutualism (biology), mutualistic relationship with ants, which feed on the honeydew and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominican Amber
Dominican amber is amber from the Dominican Republic derived from resin of the extinct tree ''Hymenaea protera''. Dominican amber differentiates itself from Baltic amber by being nearly always transparent, and it has a higher number of fossil inclusions. This has enabled the detailed reconstruction of the ecosystem of a long-vanished tropical forest.George Poinar, Jr. and Roberta Poinar, 1999. ''The Amber Forest: A Reconstruction of a Vanished World'', (Princeton University Press) Age A study in the early 1990s returned a date up to 40 million years old. However, according to Poinar, Dominican amber dates from Oligocene to Miocene, thus about 25 million years old. The oldest, and hardest of this amber comes from the mountain region north of Santiago. The ''La Cumbre'', ''La Toca'', ''Palo Quemado'', ''La Bucara'', and ''Los Cacaos'' mining sites in the ''Cordillera Septentrional'' not far from Santiago. Amber has also been found in the south-eastern Bayaguana/Sabana de la Mar a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.
