The southern gastric-brooding frog was discovered in 1972 and described in 1973, [2] though there is one publication suggesting that the species was discovered in 1914 (from the Blackall Range). [ 3 ] [ 4 ] Rheobatrachus silus was restricted to the Blackall Range and Conondale Ranges in southeast Queensland , north of Brisbane , between ...
These scientists from the University of Newcastle Australia led by Prof Michael Mahony, who was the scientist who first discovered the northern gastric-brooding frog, Simon Clulow and Prof Mike Archer from the University of New South Wales hope to continue using somatic-cell nuclear transfer methods to produce an embryo that can survive to the ...
Indobatrachus (Greek for "Indian frog") is an extinct genus of frog known from the Early Paleocene of India. [1] [2] It contains a single species, Indobatrachus pusillus.Two other species, I. trivialis and I. malabaricus, were also previously described, but these have since been synonymized with I. pusillus.
Distribution of the northern gastric-brooding frog (blue). The northern gastric-brooding frog (Rheobatrachus vitellinus) was discovered in 1984 by Michael Mahony. [2]It was restricted to the rainforest areas of the Clarke Range in Eungella National Park and the adjacent Pelion State Forest in central eastern Queensland.
In 1992 an experimental translocation experiment was being conducted to determine the cause of population declines in T. acutirostris.Frogs and tadpoles from a stream in the north of the species range were collected and placed into observation enclosures at five sites to the south where the species had disappeared and in a control enclosure at the collection site.
The most common fossil at the site are of crocodiles and giant trionychidae turtles which have become extinct in Australia. [4] Fossils from Murgon include the world's oldest songbirds, the oldest Australian marsupials, and the only fossils of leiopelmatid frogs outside of the Saint Bathans Fauna.
The oldest-known frog fossils date to even earlier. Scientists in Argentina have discovered excellently preserved fossil remains of the oldest-known tadpole, the larval stage of a large frog ...
