Leiopelma
__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] |
Hamilton's Frog
The Hamilton's frog ''(Leiopelma hamiltoni)'' is a primitive frog native to New Zealand, one of only four extant species belonging to the family Leiopelmatidae. New Zealand's frog species all are in the family Leiopelmatidae. The male remains with the eggs to protect them and allows the tadpoles to climb onto his back where they are kept moist. It is named in honour of Harold Hamilton the collector of the type specimen. The holotype is in the collection of the Museum of New Zealand Te Papa Tongarewa. Description They are mostly light brown in colour, although some green individuals have also been observed. A single dark stripe runs along each side of the head and through the eye. There is no webbing between the hind toes, and the fingers are not webbed. These frogs have a snout length of 5.5 mm, and thighs that can reach up to 14.8 mm. Leiopelma hamiltoni is a very small frog species, with males being even smaller than females. Males have a snout-vent length of up to 43 millimeter ...

Hochstetter's Frog
Hochstetter's frog or Hochstetter's New Zealand frog (''Leiopelma hochstetteri'') is a primitive frog native to New Zealand, one of only four extant species belonging to the taxonomic family Leiopelmatidae. They possess some of the most ancient features of any extant frogs in the world. Taxonomy Hochstetter's frog is named after the Austrian geologist Ferdinand von Hochstetter. This species is endemic to New Zealand and belongs to the most primitive anuran suborder Archaeobatrachia, along with Archey's frog (''Leiopelma archeyi''), Hamilton's frog (''L. hamiltoni''), and the Maud Island frog (''L. pakeka''). Three species within the genus, '' L. auroraensis'', '' L. markhami'', and '' L. waitomoensis'', are extinct. Description Hochstetter's frog has a brown-green to brown-red top with dark bands and warts, yellow-brown bellies. Males grow to and females snout–vent length. They are nocturnal, staying under refugia during the day. Hochstetter's frog prefers moist gaps under s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maud Island Frog
__NOTOC__ The Maud Island frog (''Leiopelma pakeka'') is a primitive frog native to New Zealand, one of only four extant species belonging to the family Leiopelmatidae. Description ''Leiopelma pakeka'' is a small terrestrial frog, growing to 5 cm in length, and is medium to dark brown with unwebbed toes and a distinctive extended ridge behind its eyes. It is slightly larger than and differs slightly in colour from Hamilton's frog ('' Leiopelma hamiltoni''). Like other members of the genus '' Leiopelma'', Maud Island frogs lay their eggs on moist ground. One to 19 eggs are laid in December, and are guarded by the male for 14–21 weeks. The eggs hatch into froglets, which the male carries on his back until they become independent. Long-term studies beginning in 1983 have revealed this species is extremely long-lived: some monitored frogs reach 35–40 years old, making them the longest-lived wild frog in the world. Individuals are well-camouflaged and sedentary, spending th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archey's Frog
Archey's frog (''Leiopelma archeyi'') is an archaic species of frog endemic to the North Island of New Zealand. It is one of only three extant species belonging to the taxonomic family Leiopelmatidae. It is named after Sir Gilbert Archey, the former director of the Auckland Institute. The holotype is held at the Auckland War Memorial Museum. It is found only in the Coromandel Peninsula and near Te Kuiti in the North Island of New Zealand. This species, along with others in the family, have changed little over the past 200 million years, thus they represent "living fossils". Ecology The species is fully terrestrial, living and reproducing under damp vegetation in native forests. Currently, its distribution is confined to higher elevations at just two localities, although just 25 years ago, the species was abundant in a much wider range, down to sea level. Little is known about the natural history of this species. Although the species is sexually monomorphic, males are believed ...

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. See also *List of extinct animals of New Zealand *List of amphibians of New Zealand All of the amphibians of New Zealand are either from the endemic genus '' Leiopelma'' or are one of the introduced species, of which three are extant.

Leiopelma Waitomoensis
The Waitomo frog (''Leiopelma waitomoensis'') is an extinct species of the genus ''Leiopelma'' from New Zealand. The Waitomo frog's distribution was solely in the North Island of New Zealand. Its extinction is believed to have happened during the last 1000 years. Its subfossil remains were discovered at a cave near Waitomo. ''L. waitomoensis'' was a large, robust frog, and presumably many times heavier than other native frogs. It was around 100 mm in length, about twice the size of any other native New Zealand frogs. It was first described by Trevor H. Worthy in 1987 along with the Aurora frog and Markham's frog.

Leiopelma Auroraensis
''Leiopelma auroraensis'', known as the Aurora frog, is an extinct species of frog that was found in New Zealand. One subfossil of the Aurora frog has been discovered in the Aurora Cave, Fiordland, New Zealand. It measured about 60 mm from the snout to the vent. It is named after the Aurora Cave for where it was found. The other extinct New Zealand frogs are Markham's frog and Waitomo frog. Aurora frog probably was a local form that had evolved from the more widely distributed Markham's frog.

Ascaphidae
The tailed frogs are two species of frogs in the genus ''Ascaphus'', the only taxon in the family Ascaphidae . The "tail" in the name is actually an extension of the male cloaca. The tail is one of two distinctive anatomical features adapting the species to life in fast-flowing streams. These are the only North American frog species that reproduce by internal fertilization. They are among the most primitive known families of frogs. Its scientific name means 'without a spade', from the privative prefix '' a-'' and the Ancient Greek ' (, 'spade, shovel'), referring to the metatarsal spade, which these frogs do not have. Taxonomy Until 2001, the genus was believed to be monotypic, the single species being the tailed frog (''Ascaphus truei'' Stejneger, 1899). However, in that year, Nielson, Lohman, and Sullivan published evidence that promoted the Rocky Mountain tailed frog (''Ascaphus montanus'') from a subspecies to its own species. Since then, the former species has been forma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint 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.
