Meinertellidae
The Meinertellidae are a small family of basal insects belonging to the order Archaeognatha. They are sometimes known as rock bristletails. These insects can be distinguished from members of the other Archaeognatha family, Machilidae, by the lack of scales at the base of the legs and antennae, head, and palps; along with possession of small abdominal sternites protruding slightly between the coxal plates. They can also be distinguished by patches of reddish to violet-brown hypodermal pigment on the appendages. Meinertellidae currently contains more than 170 species over 19 genera, clustered into the following groups: ''Machiloides, Machilinus, Hypomachiloides, Machilontus,'' and ''Meinertellus''. Distribution These insects are principally found in the southern hemisphere, and can be found in rain forests, regular forests, and on coastal cliffs.

Archaeognatha
The Archaeognatha are an order of apterygotes, known by various common names such as jumping bristletails. Among extant insect taxa they are some of the most evolutionarily primitive; they appeared in the Middle Devonian period at about the same time as the arachnids. Specimens that closely resemble extant species have been found as both body and trace fossils (the latter including body imprints and trackways) in strata from the remainder of the Paleozoic Era and more recent periods. For historical reasons an alternative name for the order is Microcoryphia. Until the late 20th century the suborders Zygentoma and Archaeognatha comprised the order Thysanura; both orders possess three-pronged tails comprising two lateral cerci and a medial epiproct or ''appendix dorsalis''. Of the three organs, the appendix dorsalis is considerably longer than the two cerci; in this the Archaeognatha differ from the Zygentoma, in which the three organs are subequal in length. In the late 20th cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machilinus
''Machilinus'' is a genus of rock bristletails in the family Meinertellidae. There are about 17 described species in ''Machilinus''. The members of the genus are active during the day ( diurnal).

Machilidae
The Machilidae are a family of insects belonging to the order Archaeognatha (the bristletails). There are around 250 described species worldwide. These insects are wingless, elongated and more or less cylindrical with a distinctive humped thorax and covered with tiny, close-fitting scales. The colour is usually grey or brown, sometimes intricately patterned. There are three "tails" at the rear of the abdomen: two cerci and a long central epiproct. They have large compound eyes, often meeting at a central point. They resemble the silverfish and the firebrat, which are from a different order, Zygentoma. Machilids undergo virtually no metamorphosis during their life cycles, and both nymphs and adults are generally inconspicuous herbivores and scavengers. Many species are restricted to rocky shorelines, but some are found in well-vegetated habitats inland. They can move very fast and often escape by jumping considerable distances when disturbed. Like all Archaeognatha, machilid ... [...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 ...

Karl Wilhelm Verhoeff
Karl (or Carl) Wilhelm Verhoeff (25 November 1867 – 6 December 1944) was a German myriapodology, myriapodologist and entomology, entomologist, specialising in myriapods (millipedes, centipedes, and related species) as well as woodlouse, woodlice and to a lesser extent insects. Biography Karl W. Verhoeff was born on 25 November 1867 in Soest, Germany, Soest in Westphalia, the son of the apothecary Karl M. Verhoeff and his wife Mathilde (born Rocholl). He completed his ''Abitur'' examination in Soest in 1889 and completed his doctoral thesis in zoology in Bonn in 1893. In 1902 he married Marie Kringer, who died in 1937 during surgery. The marriage produced three children, two daughters and a son, the son dying in 1942 on the Eastern Front (World War II), Russian front. He was briefly employed (1900–1905) at the ' in Berlin, but for the remainder of his long career, he worked privately. Verhoeff undertook a number of collecting trips, including visits to the French Riviera, and R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mexican Amber
Mexican amber, also known as Chiapas Amber is amber found in Mexico, created during the Early Miocene and middle Miocene epochs of the Cenozoic Era in southwestern North America. As with other ambers, a wide variety of taxa have been found as inclusions including insects and other arthropods, as well as plant fragments and epiphyllous fungi. Context Mexican amber is mainly recovered from fossil bearing rocks in the Simojovel region of Chiapas, Mexico. It is one of the main minerals recovered in the state of Chiapas, much of which is from 15 to 23 million years old, with quality comparable to that found in the Dominican Republic. Chiapan amber has a number of unique qualities, including much that is clear all the way through and some with fossilized insects and plants. Most Chiapan amber is worked into jewelry including pendants, rings and necklaces. Colors vary from white to yellow/orange to a deep red, but there are also green and pink tones as well. Since pre-Hispanic time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominican Amber
Dominican amber is amber from the Dominican Republic derived from resin of the extinct tree ''Hymenaea protera''. Dominican amber differentiates itself from Baltic amber by being nearly always transparent, and it has a higher number of fossil inclusions. This has enabled the detailed reconstruction of the ecosystem of a long-vanished tropical forest.George Poinar, Jr. and Roberta Poinar, 1999. ''The Amber Forest: A Reconstruction of a Vanished World'', (Princeton University Press) Age A study in the early 1990s returned a date up to 40 million years old. However, according to Poinar, Dominican amber dates from Oligocene to Miocene, thus about 25 million years old. The oldest, and hardest of this amber comes from the mountain region north of Santiago. The ''La Cumbre'', ''La Toca'', ''Palo Quemado'', ''La Bucara'', and ''Los Cacaos'' mining sites in the ''Cordillera Septentrional'' not far from Santiago. Amber has also been found in the south-eastern Bayaguana/Sabana de la Mar a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
