Chiapan 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 times, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coelomycetes
Coelomycetes are a form-class of fungi, part of what has often been referred to as Fungi imperfecti, Deuteromycota, or anamorphic fungi. These are conidial fungi where the conidia form in a growing cavity in the host's tissue. The fruiting structures are spherical with an opening at the apex (pycnidia) or are disc-shaped (acervuli). The formation of conidia in a fruiting body separates this group from the hyphomycetes, who have "naked" conidia. Franz Xaver Rudolf von Höhnel (1852–1920), an Austrian bryologist, mycologist and algologist, was known for his contributions to the taxonomy of the Coelomycetes. Orders * Melanconiales (producing spores in acervuli) * Sphaeropsidales (producing spores in pycnidia A pycnidium (plural pycnidia) is an asexual fruiting body produced by mitosporic fungi, for instance in the order Sphaeropsidales ( Deuteromycota, Coelomycetes) or order Pleosporales (Ascomycota, Dothideomycetes).
