Messelepone Leptogenoides
''Messelepone'' is an extinct genus of ants in the formicid subfamily Ponerinae described from fossils found in Europe. ''M. leptogenoides'' is the only species assigned to the genus, which is one of several Lutetian Ponerinae genera. History and classification When described, ''Messelepone'' was known from two fossil insects which are compression-impression fossils preserved in layers of soft sedimentary rock. Along with other well preserved insect fossils, the ''Messelepone'' specimens were collected from layers of the Lutetian Messel pit World Heritage Site. The formation is composed of brown coals, oil shales, and bituminous shale, which preserved numerous insects, fish, birds, reptiles, and terrestrial mammals as a notable lagerstätten. The area is a preserved maar lake which initially formed approximately 47 million years ago as the result of volcanic explosions. At the time of description, the holotype queen and paratype male specimens were preserved in the Senc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutetian
The Lutetian is, in the geologic timescale, a stage (stratigraphy), stage or age (geology), age in the Eocene. It spans the time between . The Lutetian is preceded by the Ypresian and is followed by the Bartonian. Together with the Bartonian it is sometimes referred to as the Middle Eocene Subepoch. Stratigraphic definition The Lutetian was named after Lutetia, the Latin language, Latin name for the city of Paris. The Lutetian Stage was introduced in scientific literature by French geologist Albert de Lapparent in 1883 and revised by A. Blondeau in 1981. The base of the Lutetian Stage is at the first appearance of the nanofossil ''Blackites inflatus'', according to an official reference profile (GSSP) established in 2011. Of two candidates located in Spain, the Gorrondatxe section was chosen.See thwebsite of Eustoquio Molinafor these candidates. The top of the Lutetian (the base of the Bartonian) is at the first appearance of calcareous nanoplankton species ''Reticulofenestra ...

Naturmuseum Senckenberg
The Naturmuseum Senckenberg is a museum of natural history, located in Frankfurt am Main. It is the second-largest of its type in Germany. The museum contains a large and diverse collection of birds with 90,000 bird skins, 5,050 egg sets, 17,000 skeletons, and 3,375 spirit specimens (a specimen preserved in fluid). In 2010, almost 517,000 people visited the museum. The building housing the Senckenberg Museum was erected between 1904 and 1907 outside of the center of Frankfurt in the same area as the Johann Wolfgang Goethe University, which was founded in 1914. The museum is owned and operated by the Senckenberg Nature Research Society, which began with an endowment by Johann Christian Senckenberg. Attractions include a '' Diplodocus'' (donated by the American Museum of Natural History on the occasion of the present museum building's inauguration in 1907), the crested Hadrosaur ''Parasaurolophus'', a fossilized ''Psittacosaurus'' with clear bristles around its tail and visi ...

Pachycondyla
''Pachycondyla'' is a Ponerinae, ponerine genus of ants found in the Neotropics. Distribution ''Pachycondyla'' is currently distributed from southern United States to northern Argentina, but some fossil species (e.g. ''Pachycondyla eocenica, P. eocenica'' and ''Pachycondyla lutzi, P. lutzi'') are found in Europe. Species The genus formerly contained hundreds of species, most of them belonging to at the time junior synonyms of ''Pachycondyla''. While revising the ponerines, Schmidt & Shattuck (2014) revived many of the former synonyms, leaving only eleven species in ''Pachycondyla''. They were not able to place some species with certainty, and left more than twenty species ''incertae sedis'' in ''Pachycondyla'', acknowledging that "this placement is undoubtedly incorrect". *''Pachycondyla constricticeps'' Mackay & Mackay, 2010 *''Pachycondyla crassinoda'' (Latreille, 1802) *''Pachycondyla fuscoatra'' (Roger, 1861) *''Pachycondyla harpax'' (Fabricius, 1804) *''Pachycondyla impres ...

Mesosoma
The mesosoma is the middle part of the body, or tagma, of arthropods whose body is composed of three parts, the other two being the prosoma and the metasoma. It bears the legs, and, in the case of winged insects, the wings. In hymenopterans of the suborder Apocrita (wasps, bees and ants), it consists of the three thoracic segments and the first abdominal segment (the propodeum). For historical reasons, in ants it is commonly referred to by the alternative name alitrunk. In scorpions, it is composed of six segments and forms the first part of the abdomen, containing all of the major organs. The first segment contains the sexual organs as well as a pair of vestigial and modified appendages forming a structure called the genital operculum. The second segment bears a pair of featherlike sensory organs known as the pectines; the final four segments each contain a pair of book lungs. The mesosoma is armoured with chitinous plates, on the upper surface by the tergites and on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ectatomminae
Ectatomminae is a subfamily of ants in the poneromorph subfamilies group containing four extant and three extinct genera in two tribes. The subfamily was created in 2003 when Barry Bolton divided the Ponerinae subfamily into six subfamilies.

Amblyoponinae
Amblyoponinae is a subfamily of ants in the poneromorph subfamilies group containing 13 extant genera and one extinct genus. The ants in this subfamily are mostly specialized subterranean predators. Adult workers pierce the integument (non lethally) of their larvae and pupa to imbibe haemolymph, earning them the common name Dracula ant. Identification Amblyoponinae is characterized by these worker characters: eyes small or absent, situated behind midlength of side of head; anterior margin of clypeus with specialized dentiform setae; promesonotal suture flexible; petiole very broadly attached to abdominal segment 3 and without a distinct posterior face; postpetiole absent; sting present and well developed. Systematics The subfamily was formerly considered a tribe within Ponerinae, but was elevated to its own subfamily in 2003 when Barry Bolton Barry Bolton is an English Myrmecology, myrmecologist, an expert on the classification, systematics, and taxonomy of ants, who long w ...

Casaleia
''Casaleia'' is an extinct genus of ants in the formicid subfamily Amblyoponinae described by Pagliano & Scaramozzino in 1990 from fossils found in Europe. The genus contains four species dating from the Eocene to Miocene, ''Casaleia eocenica'', ''Casaleia inversa'', ''Casaleia longiventris'', ''Casaleia orientalis''. History and classification The species placed in ''Casaleia'' have a varied history, with the type species ''Casaleia inversa'' originally described by Gennady Dlussky in 1981 as ''"Protamblyopone" inversa''. The fossil was recovered from Middle Miocene age sediments exposed in the Chon-Tyz mine, Naryn Region, Kyrgyzstan. However "Protamblyopone" was already used by William Morton Wheeler as a subgenus of '' Amblyopone''. To correct the homonym status, the species was moved to the new genus ''Casaleia'' by Pagliano and Scaramozzino in a 1990 paper. The second species in the genus, ''C. eocenica'', is of Lutetian age, and was recovered as a solitary compres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
