Boyeria Europaea Holotype MNHN
''Boyeria'' is a genus of dragonfly in the family Aeshnidae, commonly called spotted darners. They occur in temperate North America and Eurasia. The name ''Boyeria'' commemorates the French entomologist Etienne Laurent Joseph Hippolyte Boyer de Fonscolombe The genus contains the following seven described species A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction.

Sphecomyrminae
Sphecomyrminae is an extinct subfamily of ants in family Formicidae known from a series of Cretaceous fossils found in North America, Europe, and Asia. Sphecomyrminae contains eight genera, divided into two tribes Sphecomyrmini and Zigrasimeciini. The tribe Sphecomyrmini contains the six genera '' Armania'', '' Cretomyrma'', '' Gerontoformica'', '' Orapia'', '' Pseudarmania'' and '' Sphecomyrma''; while Zigrasimeciini contains '' Boltonimecia'' and '' Zigrasimecia''. A number of taxa have been removed from the subfamily and placed either in other subfamilies or are now treated as ''incertae sedis'' in Formicidae. Sphecomyrminae is the most basal of the Formicidae subfamilies, but has not been included in several phylogenetic studies of the family. Symplesiomorphies of the subfamily include the structure of the antenna, which has a short basal segment and a flexible group of segments below the antenna tip. The petiole is low and rounded, with an unrestricted gaster and the presen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haidomyrmex Cerberus
''Haidomyrmex'' is an extinct genus of ants in the formicid subfamily Haidomyrmecinae, and is one of nine genera placed in the subfamily Haidomyrmecinae. The genus contains three described species ''Haidomyrmex cerberus'', ''Haidomyrmex scimitarus'', and ''Haidomyrmex zigrasi''. All three are known from single Late Cretaceous fossils which have been found in Asia. ''H. cerberus'' is the type species and ''Haidomyrmex'' the type genus for the subfamily Haidomyrmecinae. History and classification ''Haidomyrmex,'' is known from three solitary adult fossil specimens which are composed of mostly complete adult females which have been preserved as an inclusions in transparent chunk of Burmese amber. The amber specimens entombing ''H. scimitarus'', and ''H. zigrasi'' were recovered from deposits in Kachin State, west of Myitkyna town in Myanmar. In contrast, type specimen of ''H. cerberus'' was collected in the early 1900s from an unspecified location in Myanmar. Burmese amber ha ...

Megapodagrionidae
Megapodagrionidae is a family of damselflies. They are commonly called flatwings for their habit of spreading out their wings horizontally when at rest. A 2013 phylogenetic analysis pares down this family into only three genera, and numerous other genera are now placed in different families, including Amanipodagrionidae, Argiolestidae, Heteragrionidae, Hypolestidae, Lestoideidae, Mesagrionidae, Mesopodagrionidae, Philogeniidae, Philosinidae, Protolestidae, Rhipidolestidae Rhipidolestidae is a family of damselflies in the order Odonata Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the '' Epiophlebia'' damsel-dragonflies).

Turolian
The Turolian age is a period of geologic time (9.0–5.3 Ma) within the Miocene used more specifically with European Land Mammal Ages. It precedes the Ruscinian age and follows the Vallesian age. The Turolian overlaps the Tortonian and Messinian The Messinian is in the geologic timescale the last age or uppermost stage of the Miocene. It spans the time between 7.246 ± 0.005 Ma and 5.333 ± 0.005 Ma (million years ago). It follows the Tortonian and is followed by the Zanclean, the fir ... ages. ;References Miocene {{geochronology-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vallesian
The Vallesian age is a period of geologic time (11.6–9.0 Ma) within the Miocene used more specifically with European Land Mammal Ages. It precedes the Turolian age and follows the Astaracian age. The so-called Vallesian Crisis resulted in the extinction of several mammalian taxa characteristic of the Middle Miocene. The term "Vallesian" was introduced by Catalan palaeontologist Miquel Crusafont in 1950 to mark the arrival of the equid '' Hipparion'' in Europe. The remaining European palaeofaunas, however, had been around since the Middle Miocene, including the moschid '' Micromeryx'' (a musk deer), the cervid '' Euprox'', the suid '' Listriodon'', and the felids '' Sansanosmilus'' and '' Pseudaelurus'', and the Aragonian-Vallesian"Aragonian" is a Spanish term for a continental stage, roughly equivalent to the Middle Miocene or Astaracian (16–11 Ma). boundary does not represent a major shift in the European mammalian record.

Burmomyrma Rossi BMNHP19125 01
''Burmomyrma'' is an extinct genus of aculeate hymenopteran, suggested to be an ant. The genus contains a single described species, ''Burmomyrma rossi''. ''Burmomyrma'' is known from a single Middle Cretaceous fossil which was found in Asia. History and classification ''Burmomyrma'' is known from a solitary adult fossil, the holotype, specimen number BMNH 19125. While the type specimen was collected in the early 1900s and deposited in the Natural History Museum in London, description of the specimen did not occur until nearly 80 years later. The holotype specimen is composed of a mostly complete adult female which has been preserved as an inclusion in transparent chunks of deep yellow and relatively clear Burmese amber. The amber specimen was recovered from deposits in Kachin State of Myanmar. Burmese amber has been radiometrically dated using U- Pb isotopes, yielding an age of approximately 99 million years old, close to the Albian – Cenomanian boundary. The fo ...

Aneuretinae
Aneuretinae is a subfamily of ants consisting of a single extant species, ''Aneuretus simoni'' ( Sri Lankan relict ant), and 9 fossil species. Earlier, the phylogenetic position of ''A. simoni'' was thought to be intermediate between primitive and advanced subfamilies of ants, but recent studies have shown it is the nearest living relative of subfamily Dolichoderinae.

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 the potential role of the amber trade 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 in the Hukawng Basin, a large Cretaceous-Cenozoic sedimentary basin within north ...
