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.

Formation (stratigraphy)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness (geology), thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coleoptera
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geologic Formations Of Canada
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of ...

Palaeontology (journal)
''Palaeontology'' is one of the two scientific journals of the Palaeontological Association (the other being '' Papers in Palaeontology''). It was established in 1957 and is published on behalf of the Association by Wiley-Blackwell. The editor-in-chief is Barry Lomax (University of Nottingham). ''Palaeontology'' publishes articles on a range of palaeontological topics, including taphonomy, functional morphology, systematics, palaeo-environmental reconstruction and biostratigraphy. According to the ''Journal Citation Reports'', the journal has a 2017 impact factor The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as i ... of 3.730, ranking it 1st out of 55 journals in the category "Paleontology".

Dictyoptera
Dictyoptera (from Greek δίκτυον ''diktyon'' "net" and πτερόν ''pteron'' "wing") is an insect superorder that includes two extant orders of polyneopterous insects: the order Blattodea (termites and cockroaches together) and the order Mantodea (mantises). While all modern Dictyoptera have short ovipositors, the oldest fossils of Dictyoptera have long ovipositors, much like members of the Orthoptera. Classification and phylogeny The use of the term Dictyoptera has changed over the years, and while largely out of use for much of the last century, it is becoming more widely used. It has usually been considered a superorder, with Isoptera, Blattodea and Mantodea being its three orders. In some classifications, however, Dictyoptera is shifted to order status and in others the order Isoptera has been subsumed under Blattodea while retaining Dictyoptera as a superorder. Regardless, in all classifications the constituent groups are the same, just treated at different rank. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tettigarctidae
The Tettigarctidae, known as the hairy cicadas, are a small relict (mostly extinct) family of primitive cicadas. Along with more than 20 extinct genera, Tettigarctidae contains a single extant genus, ''Tettigarcta'', with two extant species, one from southern Australia ('' T. crinita'') and one from the island of Tasmania ('' T. tomentosa''). Numerous fossil species have been described from the Late Triassic onwards. ''Tettigarcta'' are the closest living relatives of the true cicadas.

''Peltodytes'' is a genus of water beetle which is native to the Nearctic, Europe, the Near East, and North Africa North Africa, or Northern Africa is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region, and it is sometimes defined as stretching from the Atlantic shores of Mauritania in .... ''Peltodytes'' can generally be differentiated from the similar '' Haliplus'' by the presence of a pair of spots on the posterior margin of the pronotum.
