Procercopidae
Procercopidae is an extinct family of froghoppers. They are known from the Early Jurassic to early Late Cretaceous of Eurasia. They are one of two main families of Mesozoic froghoppers alongside Sinoalidae. Procercopidae are considered to be the ancestral group from which modern froghoppers are derived. Taxonomy Chen et al, 2020 found that the family was paraphyletic with respect to extant froghoppers and the monotypic family Cercopionidae known from the Aptian aged Crato Formation of Brazil. * †'' Anomoscytina'' Ren et al. 1998 Yixian Formation, China, Aptian ** †''Anomoscytina anomala'' Ren et al. 1998 * †'' Anthoscytina'' Hong 1983 ** †''Anthoscytina brevineura'' Chen et al. 2015 Daohugou, China, Callovian ** †''Anthoscytina daica'' Shcherbakov 1988 Glushkovo Formation, Russia, Tithonian-Early Cretaceous ** †''Anthoscytina daidaleos'' Fu et al. 2018 Daohugou, China, Callovian ** †''Anthoscytina elegans'' Chen et al. 2015 Daohugou, China, Callovian ** †''Anthos ...

Froghoppers
The froghoppers, or the superfamily Cercopoidea, are a group of hemipteran insects in the suborder Auchenorrhyncha. Adults are capable of jumping many times their height and length, giving the group their common name, but they are best known for their plant-sucking nymphs which encase themselves in foam in springtime. Taxonomy Traditionally, most of this superfamily was considered a single family, the Cercopidae, but this family has been split into three families for many years now: the Aphrophoridae, Cercopidae, and Clastopteridae. More recently, the family Epipygidae has been removed from the Aphrophoridae. Spittlebug nymphs These families are best known for the nymph (biology), nymphal stage, which produces a cover of foamed-up plant sap visually resembling saliva; the nymphs are therefore commonly known as spittlebugs and their foam as cuckoo spit, frog spit, or snake spit. This characteristic spittle production is associated with the unusual trait of xylem feeding. Wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinoalidae
Sinoalidae is an extinct family of froghoppers known from the late Middle Jurassic to the early Late Cretaceous of Asia. They are one of two main Mesozoic families of froghoppers, alongside Procercopidae, unlike Procercopidae, Sinoalidae is thought to be an extinct side branch and not ancestral to modern froghoppers. Sinoalids have a temporally disjunct distribution being only known from the late Middle Jurassic (Callovian) Yanliao Biota of Inner Mongolia and the early Late Cretaceous (Cenomanian) aged Burmese amber of Myanmar, separated by over 60 million years. The family is "recognized by its tegmen with the costal area and clavus commonly more sclerotized and punctate than the remaining part, and its hind tibia with two rows of lateral spines" Genera Taxonomy based on Chen et al., 2019 * †'' Cretosinoala'' Fu and Huang 2019 Burmese amber, Myanmar, Cenomanian * †'' Hebeicercopis'' Hong 1983 Jiulongshan Formation, China, Callovian * †'' Huabeicercopis'' Hong 1983 Jiulo ...

Burmese Amber
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its alleged role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected. Geological context, depositional environment and age The amber is found within the Hukawng Basin, a large Cretaceous-Cenozoic sedimentary basin within northern Myanmar. The s ...

Wealden Group
The Wealden Group, occasionally also referred to as the Wealden Supergroup, is a group (a sequence of rock strata) in the lithostratigraphy of southern England. The Wealden group consists of paralic to continental (freshwater) facies sedimentary rocks of Berriasian to Aptian age and thus forms part of the English Lower Cretaceous. It is composed of alternating sands and clays. The sandy units were deposited in a flood plain of braided rivers, the clays mostly in a lagoonal coastal plain.Jackson (2008) The Wealden Group can be found in almost all Early Cretaceous basins of England: its outcrops curve from the Wessex Basin in the south to the Cleveland Basin in the northeast. It is not found in northwest England and Wales, areas which were at the time tectonic highs where no deposition took place. The same is true for the London Platform around London and Essex. Offshore, the Wealden Group can reach a thickness of 700 metres. The terms ''Wealden'' and ''Wealden facies'' are also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinuiju Formation
The Sinuiju Formation is a geologic formation in North Korea. Formerly of uncertain age, it is now thought to be Early Cretaceous. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. Compression fossils of insects are also known from the formation. Several bird fossils are found in this formation, including a very large enantiornithine specimen with a long tibia and a long pygostyle. Amphibian fossils, including frogs and lissamphibians, have also been found here. Fossil content Fish * ''Lycoptera'' sp. * Acipenseriformes indet. Amphibians * Anuran (a frog, might be referred to '' Liaobatrachus grabaui''). Pterosaurs * Anurognathidae indet. Birds * Confuciusornithidae indet.

Posidonia Shale
The Posidonia Shale (german: Posidonienschiefer, also called Schistes Bitumineux in Luxembourg) geologically known as the Sachrang Formation, is an Early Jurassic (Toarcian) geological formation of southwestern and northeast Germany, northern Switzerland, northwestern Austria, southern Luxembourg and the Netherlands, including exceptionally well-preserved complete skeletons of fossil marine fish and reptiles.W.
