Leiopelma Bishopi
__NOTOC__ ''Leiopelma'' is a genus of New Zealand primitive frogs, belonging to the suborder Archaeobatrachia. It is the only genus in the monotypic family Leiopelmatidae. The leiopelmatids' relatively basal form indicates they have an ancient lineage. While some taxonomists have suggested combining the North American frogs of the genus ''Ascaphus'' in the family Ascaphidae with the New Zealand frogs of the genus ''Leiopelma'' in the family Leiopelmatidae, the current consensus is that these two groups constitute two separate families. The four extant species of Leiopelmatidae are only found in New Zealand. Overview The New Zealand primitive frogs' defining characteristics are their extra vertebrae (for a total of nine) and the remains of the tail muscles (the tail itself is absent in adults, although it is present in the younger frogs, which need the extra skin surface until their lungs are fully developed). The family Ascaphidae (found only in North America), of the same suborde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopold Fitzinger
Leopold Joseph Franz Johann Fitzinger (13 April 1802 – 20 September 1884) was an Austrian zoologist. Fitzinger was born in Vienna and studied botany at the University of Vienna under Nikolaus Joseph von Jacquin. He worked at the Vienna Naturhistorisches Museum between 1817, when he joined as a volunteer assistant, and 1821, when he left to become secretary to the provincial legislature of Lower Austria; after a hiatus he was appointed assistant curator in 1844 and remained at the Naturhistorisches Museum until 1861. Later he became director of the zoos of Munich and Budapest. In 1826 he published ''Neue Classification der Reptilien'', based partly on the work of his friends Friedrich Wilhelm Hemprich and Heinrich Boie. In 1843 he published ''Systema Reptilium'', covering geckos, chameleons and iguanas. Fitzinger is commemorated in the scientific names of five reptiles: '' Algyroides fitzingeri'', '' Leptotyphlops fitzingeri'', '' Liolaemus fitzingerii'', ''Micrurus tener fitzi ...

Leiopelma Markhami
Markham's frog (''Leiopelma markhami'') is one of three extinct New Zealand frog species, the others being the Aurora frog (''Leiopelma auroraensis'') and Waitomo frog (''Leiopelma waitomoensis''). Subfossil bones used to describe the species were discovered at Honeycomb Hill Cave, South Island, New Zealand, but it once occurred on both South and North Islands. It is estimated that it grew between 50 and 60 mm from snout to vent and it appears to have been a very robust animal.

Discoglossidae
The Alytidae are a family of primitive frogs. Their common name is painted frogs or midwife toads. Most are endemic to Europe, but three species occur in northwest Africa, and a species formerly thought to be extinct is found in Israel. This family is also known as Discoglossidae, but the older name Alytidae has priority and is now recognized by major reference works. Some researchers, though, suggest that '' Alytes'' and ''Discoglossus'' are different enough to be treated as belonging to separate families, implying resurrection of the Discoglossidae. The term "discoglossid" has also been used to refer to many primitive fossil frogs that share plesiomorphic (ancestral) similities to alytids, but that are probably not closely related. Genera and species The family contains three extant genera, '' Alytes'', ''Discoglossus'', and '' Latonia''. The first is somewhat toad-like and can often be found on land. The second is smoother and more frog-like, preferring the water. The third ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bombinatoridae
Bombinatoridae is a family of toads found in Eurasia. Species of the family have flattened bodies and some are highly toxic. Taxonomy and systematics Fossil specimens of the genus ''Bombina'' are known from the Pliocene to the Pleistocene. The earliest fossil specimens are '' Eobarbourula'' from the Eocene of India, and '' Hatzegobatrachus'' from Late Cretaceous of Hateg island, Romania. The genus ''Barbourula'' was considered to be situated intermediate between ''Discoglossus'' and ''Bombina'', but closer to the latter, so was added to the Bombinatoridae when that family was split from the Discoglossidae. Genera Currently, there are two extant and at least two extinct genera recognised in the family Bombinatoridae: at the |
St Bathans Fauna
The St Bathans fauna is found in the lower Bannockburn Formation of the Manuherikia Group of Central Otago, in the South Island of New Zealand. It comprises a suite of fossilised prehistoric animals from the late Early Miocene (Altonian) period, with an age range of 19–16 million years ago. The layer in which the fossils are found derives from littoral zone sediments deposited in a shallow, freshwater lake, with an area of 5600 km2 from present day Central Otago to Bannockburn and the Nevis Valley in the west; to Naseby in the east; and from the Waitaki Valley in the north to Ranfurly in the south. The lake was bordered by an extensive floodplain containing herbaceous and grassy wetland habitats with peat-forming swamp–woodland. At that time the climate was warm with a distinctly subtropical Australian climate and the surrounding vegetation was characterised by casuarinas, eucalypts and palms as well as podocarps, araucarias and southern beeches.

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.
