Archijassidae
Archijassidae is an extinct family of leafhoppers known from the Late Triassic to the early Late Cretaceous. It is the oldest member of Membracoidea, and is considered ancestral to modern leaf and treehoppers. Taxonomy Shcherbakov 2012 divided the family into 3 subfamilies, Shcherbakov considered the subfamily Dellasharinae to be ancestral to modern tree and leafhoppers. * †'' Formosixinia'' Chen and Wang 2019 Burmese amber, Myanmar, Cenomanian ** †''Formosixinia aeterna'' Chen and Wang 2019 * †subfamily Archijassinae Becker-Migdisova 1962 ** †'' Archijassus'' Handlirsch 1906 *** †''Archijassus heeri'' Geinitz 1880 Green Series, Germany, Toarcian *** †''Archijassus minimus'' Martynov 1926 Karabastau Formation, Kazakhstan, Callovian *** †''Archijassus minutus'' Heer 1865 Insektenmergel Formation, Switzerland, Hettangian *** †''Archijassus morio'' Heer 1865 Insektenmergel Formation, Switzerland, Hettangian *** †''Archijassus plurinervis'' Zhang 1985 Laiyang Fo ...

Membracoidea
The superfamily Membracoidea of sap-sucking true-bugs includes two of the largest families within what used to be called the "Homoptera": the leafhoppers ( Cicadellidae) and the treehoppers ( Membracidae). The other families in this group are quite small, and have, at various points, generally been included as members within other families, though they are all presently considered to be valid, monophyletic groups. The relict family Myerslopiidae Myerslopiidae is a family of tree-hoppers which consist of about 20 species in three genera with a distribution limited to New Zealand and Chile. Adult hoppers have a strongly sclerotized body with elytra-like tegmina meeting along the median. Th ... is restricted to New Zealand and South America while the Melizoderidae consist of two genera restricted to South America. The great diversity of Neotropical taxa suggests that the group originated in that region. The Membracoidea share the following anatomical characteristics, a tentori ...

Leafhopper
A leafhopper is the common name for any species from the family Cicadellidae. These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones. They undergo a partial metamorphosis, and have various host associations, varying from very generalized to very specific. Some species have a cosmopolitan distribution, or occur throughout the temperate and tropical regions. Some are pests or vectors of plant viruses and phytoplasmas. The family is distributed all over the world, and constitutes the second-largest hemipteran family, with at least 20,000 described species. They belong to a lineage traditionally treated as infraorder Cicadomorpha in the suborder Auchenorrhyncha, but as the latter taxon is probably not monophyletic, many modern au ...

Lulworth Formation
The Lulworth Formation is a Formation (geology), geologic formation in England. It dates from the late Tithonian to the mid Berriasian. It is a subunit of the Purbeck Group. In Dorset, it consists of three members, which are in ascending order, the Mupe Member, the Ridgway Member, and the Warbarrow Tout Member. The Mupe Member is typically 11 to 16 m thick and largely consists of marls and micrites with interbeds of calcareous mudstone. The Ridgeway Member is about 3 to 7 m thick and consists of in its western portion carbonaceous muds, marls and micrites, in the east the muds are replaced by micritic limestone. The Warbarrow Tout Member is 17 to 39 m thick and consists of limestone at the base and micrite and mudstone for the rest of the sequence, this member is the primary source of the vertebrate fossils within the formation. Elsewhere the unit is undifferentiated. Vertebrate paleobiota Amphibians Turtles Lepidosaurs Crocodyliformes Dinosaurs Mammals ...

Koonwarra, Victoria
Koonwarra is a town in the South Gippsland region of Victoria, Australia. At the , Koonwarra had a population of 404. The town straddles the South Gippsland Highway. Located around 128 km southeast of Melbourne, the town was served by rail from the 1890s until 1991 with the closing of the rail line to Barry Beach. Koonwarra fossil bed The Koonwarra fossil bed was found by accident in 1961 during roadworks to realign a segment of the South Gippsland Highway. Dating from the early Cretaceous 115 million years ago, it is composed of mudstone sediment thought to have been laid down in a freshwater (possibly cool-climate subalpine) lake. The site is an important element of Australia's fossil record, with plants, insects (including mayflies, dragonflies, cockroaches, beetles, fleas, flies and wasps), spiders, crustaceans and fish recovered. Among them is the unusual finding of a fossil horseshoe crab described as '' Victalimulus mcqueeni''. Small segments of a leafy twig have been ...
