Tick Bite
Ticks (order Ixodida) are parasitic arachnids that are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, species, and "fullness". Ticks are external parasites, living by hematophagy, feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families, the Ixodidae or hard ticks, and the Argasidae, or soft ticks. ''Nuttalliella,'' a genus of tick from southern Africa is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalothorax and abdomen are completely fuse ...

Albian
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column.

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Amblyomma
''Amblyomma'' is a genus of hard ticks. Some are disease vectors, for example the Rocky Mountain spotted fever in Brazil or ehrlichiosis in the United States. This genus is the third largest in the family Ixodidae, with its species primarily occupying the torrid zones of all the continents. The centre of species diversity is on the American continent, where half of all the species occur. On this continent, ''Amblyomma'' species reach far beyond the torrid zone, up to the 40th parallel in the Northern Hemisphere, to the 50th parallel in the Southern Hemisphere, and even reaches the alpine zone of the Andes. They also occur in Eurasia, Africa and Australia. G. V.

Deinocroton
''Deinocroton'' is an extinct genus of tick. It is known from two species found in Burmese amber, dating to the earliest part of the Cenomanian stage of the Late Cretaceous, around 99 million years ago. Amongst the oldest ticks known, it is distinct from the main two living families of ticks, Ixodidae (hard bodied) and Argasidae (soft bodied), as well as ''Nuttalliella,'' and has been placed in the monotypic family Deinocrotonidae. Taxonomy Two species have been named, ''D. draculi'' and ''D. copia,'' both from Burmese amber, which dates to the late Albian-early Cenomanian stages of the Cretaceous period, around 100 million years ago. Etymology The name of the genus ''Deinocroton'' is composed of two words from the ancient Greek "deinos", "terrible", and "krotṓn", "krotṓn", "tick". The name of the species ''draculi'' refers to the vampire Count Dracula from the epistolary novel ''Dracula'' by British writer Bram Stoker. Description ''Deinocroton'' is distinguished from ...

Khimaira Fossus
The Chimera ( or ), also Chimaera (''Chimæra'') (Ancient Greek: , ''Chímaira'' means 'she-goat'), according to Greek mythology, was a monstrous fire-breathing hybrid creature, composed of different animal parts from Lycia, Asia Minor. It is usually depicted as a lion, with the head of a goat protruding from its back, and a tail that might end with a snake's head. It was an offspring of Typhon and Echidna and a sibling of monsters like Cerberus and the Lernaean Hydra. The term "chimera" has come to describe any mythical or fictional creature with parts taken from various animals, to describe anything composed of disparate parts or perceived as wildly imaginative, implausible, or dazzling. Family According to Hesiod, the Chimera's mother was a certain ambiguous "she", which may refer to Echidna, in which case the father would presumably be Typhon, though possibly (unlikely) the Hydra or even Ceto was meant instead. However, the mythographers Apollodorus (citing Hesiod as hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

New Jersey Amber
New Jersey Amber, sometimes called Raritan amber, is amber found in the Raritan and Magothy Formations of the Central Atlantic (Eastern) coast of the United States. It is dated to the Late Cretaceous, Turonian age, based on pollen analysis of the host formations. It has been known since the 19th century, with several of the old clay-pit sites now producing many specimens for study. It has yielded a number of organism fossils, including fungi, plants, tardigrades, insects and feathers. The first identified Cretaceous age ant was described from a fossil found in New Jersey in 1966. Occurrence Though named after New Jersey, the fossil-bearing strata of the Raritan and overlying Magothy formations are also exposed in several neighboring U.S. states, including Maryland through south and central New Jersey, across Staten Island and Long Island (coastal areas of New York state), to a northern exposure at Martha's Vineyard, an island of Massachusetts. Of the two formations that New Je ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turonian
The Turonian is, in the ICS' geologic timescale, the second age in the Late Cretaceous Epoch, or a stage in the Upper Cretaceous Series. It spans the time between 93.9 ± 0.8 Ma and 89.8 ± 1 Ma (million years ago). The Turonian is preceded by the Cenomanian Stage and underlies the Coniacian Stage. At the beginning of the Turonian an oceanic anoxic event (OAE 2) took place, also referred to as the Cenomanian-Turonian boundary event or the "Bonarelli Event". Stratigraphic definition The Turonian (French: ''Turonien'') was defined by the French paleontologist Alcide d'Orbigny (1802–1857) in 1842. Orbigny named it after the French city of Tours in the region of Touraine (department Indre-et-Loire), which is the original type locality. The base of the Turonian Stage is defined as the place where the ammonite species '' Watinoceras devonense'' first appears in the stratigraphic column. The official reference profile (the GSSP) for the base of the Turonian is located in the Roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pan ...

Holothyrida
The Holothyrida are a small order of mites in the superorder Parasitiformes. No fossils are known. With body lengths of more than they are relatively large mites, with a heavily sclerotized body. It is divided into three families, Allothyridae, Holothyridae, and Neothyridae. In a 1998 experimental study, members of the family Allothyridae were found to ignore living animals but readily fed on the body fluids of death arthropods. The order has a distribution largely confined to former Gondwanan landmasses. They are the sister group to Ixodida (ticks).Dobson & Barker 1999 Systematics Allothyridae Allothyridae van der Hammen, 1972 — Australia, New Zealand * '' Allothyrus'' van der Hammen, 1961 :* '' Allothyrus australasiae'' (Womersley, 1935) :* '' Allothyrus constrictus'' (Domrow, 1955) * '' Australothyrus'' van der Hammen, 1983 :* '' Australothyrus ocellatus'' van der Hammen, 1983 Holothyridae Holothyridae Thorell, 1882 Sri Lanka, Indian Ocean islands, New Guinea, New ...

Acariformes
The Acariformes, also known as the Actinotrichida, are the most diverse of the two superorders of mites. Over 32,000 described species are found in 351 families, with an estimated total of 440,000 to 929,000 species, including undescribed species. Systematics and taxonomy The Acariformes can be divided into two main clades – Sarcoptiformes and Trombidiformes. In addition, a paraphyletic group containing primitive forms, the Endeostigmata, was formerly also considered distinct. The latter is composed of only 10 families of little-studied, minute, soft-bodied mites that ingest solid food, such as fungi, algae, and soft-bodied invertebrates such as nematodes, rotifers, and tardigrades. These clades were formerly considered suborders, but this does not allow for a sufficiently precise classification of the mites and is abolished in more modern treatments; the Endeostigmata are variously considered to form a suborder on their own (the old view) or are included mainly in the Sarcopt ...
