Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Zaza Formation
The Zaza Formation is a geological formation located in Buryatia (Russia). It dates to the Lower Cretaceous period. It is Aptian in age and consists of Sandstone, sandstones, Siltstone, siltstones, Marl, marls and bituminous Shale, shales, deposited in a stratified lake. It is situated on a large granite plateau in the NE of Buryatia.Zherikhin, V.V., Mostovski, M.B., Vrsansky, P., Blagoderov, V.A. and Lukashevich, E.D. 1999The unique Lower Cretaceous locality of Baissa and other contemporaneous insect-bearing sites in North and West Transbaikalia ''Proceedings of the First Palaeoentomological Conference, Moscow, 1998''. Bratislava: Amba Projects, pp. 185-192. The formation is known for its numerous compression fossils of many varieties of insect found predominantly at the Baissa locality, located on the banks of the Vitim River. Insects are found in multiple beds throughout the succession, predominantly in the finer grained facies, the preservation of insect fossils is variable bet ...

Buryatia
Buryatia, officially the Republic of Buryatia (russian: Республика Бурятия, r=Respublika Buryatiya, p=rʲɪsˈpublʲɪkə bʊˈrʲætʲɪjə; bua, Буряад Улас, Buryaad Ulas, , mn, Буриад Улс, Buriad Uls), is a republic of Russia located in Siberia. It is the historical native land of indigenous Buryats. Formerly part of the Siberian Federal District, it has been a part of the Russian Far East since 2018. Its capital is the city of Ulan-Ude, which means Red Gateway in Buryat Mongolian. Its area is with a population of 978,588 ( 2021 Census).

Cenomanian
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for marine spec ...

Redmond Formation
The Redmond Formation is a geologic formation in Newfoundland and Labrador. It preserves fossils dating back to the mid-Cretaceous (Cenomanian). It was a thin (up to thick) and restricted unit traced for in a single mine (Redmond No. 1) in Labrador, overlying Paleoproterozoic rocks, with large amounts of rubble, probably as a result of graben subsidence within the Labrador trough. Argillite facies within the formation have produced a diverse flora and insect assemblage.Demers Potvin & Larsson, 2019 Fossil content Mesoraphidiidae * '' Alloraphidia dorfi'' Palaeoleontidae * '' Palaeoleon ferrogeneticus'' Susumaniidae * '' Palaeopteron complexum'' Coleoptera * Coleoptera indet.

Santanmantis
''Santanmantis'' is an extinct genus of mantises, the sole genus in the family Santanmantidae. The only species, ''Santanmantis axelrodi'' , is known from the Crato Formation of Brazil, dating to the late Aptian The Aptian is an age in the geologic timescale or a stage in the stratigraphic column. It is a subdivision of the Early or Lower Cretaceous Epoch or Series and encompasses the time from 121.4 ± 1.0 Ma to 113.0 ± 1.0 Ma (million years ago), a ... stage of the Early Cretaceous. It is amongst the most primitive known lineages of mantis. Like other mantises, the forelegs are modified into spined raptorial appendages. When describing a new specimen in 2017, Hörnig, Haug and Haug proposed that the second set of legs also had spines similar to the forelegs, and also served a raptorial function, but that they were not visible in the fossil due to being broken off. However a response to this paper criticised this assumption, finding that it had little evidence from the fos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Insect Families
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
