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] |
Termitaradus Protera
''Termitaradus protera'' is an extinct species of termite bug in the family Termitaphididae known from several Late Oligocene to Early Miocene fossils found in Mexico. ''T. protera'' is the only species in the extant genus ''Termitaradus'' to have been described from fossils found in Mexican amber and is one of four species from new world amber; the others are ''Termitaradus avitinquilinus'', '' Termitaradus dominicanus'' and ''Termitaradus mitnicki''. ''T. protera'' was also the first termite bug described from the fossil record. History and classification ''Termitaradus protera'' is known from a series of fossil insects which are inclusions in transparent chunks of Mexican amber. An amber specimen, in the collection of W. Weitschat of Hamburg, Germany, has a total of five ''T. protera'' individuals preserved together with portions of seven worker caste termites. The amber was produced by the extinct leguminous tree ''Hymenaea mexicana'', and has dimensions o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligocene Paleontological Sites Of North America
The Oligocene ( ) is a geologic epoch (geology), epoch of the Paleogene Geologic time scale, Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of Neontology, extant forms of Mollusca, molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major ...

Geologic Formations Of Mexico
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 E ...

Hymenaea Allendis
''Hymenaea allendis'' is an extinct legume species in the family Fabaceae described from a single isolated fossil flower in amber. The species is known from a Late Oligocene to Early Miocene location in southern Mexico. Unlike the coeval extinct species '' Hymenaea mexicana'' and ''Hymenaea protera'' which are placed closer to the living species ''Hymenaea verrucosa'' of Africa, ''H. allendis'' is closer in relation to the neotropical species of ''Hymenaea''. History and classification ''Hymenaea allendis'' is known from a solitary fossil flower which is an inclusion in a transparent chunk of Mexican amber. The specimen is currently housed in the Eliseo Palacios Aguilera Paleontological Museum in Chiapas, Mexico. Mexican amber is recovered from fossil-bearing rocks in the Simojovel region of Chiapas, Mexico. The amber dates from between 22.5 million years old, for the youngest sediments of the Balumtun Sandstone, and 26 million years old for the oldest La Quinta Formation. T ...

Leptopharsa Tacanae
''Leptopharsa tacanae'' is an extinct species of lace bug in the family Tingidae. The species is solely known from the Late Oligocene to Middle Miocene Mexican amber deposits. The species is the first lace bug described from Mexican amber. History and classification ''Leptopharsa tacanae'' is known from the holotype specimen, collection number TOT158.1, which is an inclusion in a transparent chunk of Mexican amber, also known as Chiapas amber. As of 2014, the type insect was part of the David Coty fossil collection provisionally housed at the Muséum National d’Histoire Naturelle, Paris, France. This amber predates a range from between 22.5 million years old, for the youngest sediments of the Balumtun Sandstone, and 26 million years, for the La Quinta Formation. This age range, which straddles the boundary between the Late Oligocene and Early Miocene, is complicated by both formations being secondary deposits for the amber; consequently, the given age range is only the youn ...
