Pristomyrmex Picteti
''Pristomyrmex'' is a genus of ants in the subfamily Myrmicinae. Distribution and habitat The genus is composed of 59 extant species restricted to the Old World tropics and a single extinct species, ''Pristomyrmex rasnitsyni'', described from Scandinavian amber. Its center of diversity is the Oriental region, though species are also known from the Australian rainforests, Africa, Mauritius and Réunion. Most of the species inhabit the rainforest, forage as predators or scavengers, and tend to nest in soil, leaf litter or rotten wood.

Late Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
