Cyclommatus Monguillonni
''Cyclommatus'' is a genus of the family Lucanidae, also known as the stag beetle. The majority of the species from the genus ''Cyclommatus'' are located in Southeast Asia, though some species are found in China and Taiwan as well. The genus ''Cyclommatus'' also consists of three subgenera: ''Cyclommatus'' (Parry, 1863), ''Cyclommatinus'' (Robert Didier, Didier, 1927) and ''Cyclommatellus'' (Nagel, 1936). Each subgenera contains 80, 24 and 3 species respectively. In total, the genus ''Cyclommatus'' consists of a total of 134 species, though more are still being discovered to this day. The chief distinguishing characteristics of this genus are its impressive mandibles, which can sometimes be as long as its body, as well as its lustrous metallic exoskeleton, which can range from red, brown, green, purple, gold and a rarer blue-black. As such, beetles from the genus ''Cyclommatus'' can command a high price from collectors, with a demand for both live and dried specimens. The largest ...

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene 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 extant forms of 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 changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
