Bothriceps australis – Wikipedia

Bothriceps australis It is an extinct amphibian, belonging to the fears of the fears. He lived in the upper Permian (about 260 – 255 million years ago) and his fossil remains were found in Australia.

This animal was to be similar to a large salamandra with a flat, short and wide skull. The skull was almost triangular in shape, with a blunt muzzle and on the rear broadcast. The bones of the skull were adorned with small irregular polygonal dimples. The skull was just over ten centimeters long, and the entire animal was not to reach the length meter. The orbits, facing upwards, were positioned just over half of the skull towards the muzzle, and were oval in shape. Compared to other similar but subsequent genres, such as Brachyops , the muzzle was more pointed and less rounded, and the orbits were slightly more backward and less spatted. The teeth were very numerous, close to each other and pointed; Their foundations were expanded and equipped with about twelve longitudinal strie that extended to almost reach the peak of the tooth. The structure of the vertebrae recall those of Tupilakosaurus , another fear of a more basal group.

Bothriceps australis It was described for the first time in 1859 by Thomas Henry Huxley, on the basis of fossil remains found in Australia, in the Koonya area in Tasmania; The land of origin of the fossils, initially of uncertain dating, were then attributed at the end of the permian. Initially Bothriceps It has been attributed to Brachiopids, a group of typical amphibians of the Mesozoic, with flattened and rounded skulls. Subsequent analyzes have shown that Bothriceps He owned too primitive characteristics to be included in this family, and the Clade Brachyopomorpha was therefore established, also including the superfamily Brachyopoidaa (Brachyopidae and Chigutisauridae), in which Bothriceps The most basal member is. Gender Bothriceps Other species have also been attributed, such as B. major , which later was attributed to another kind of fear amphibians, Trucheosaurus . The genre Platycepsion , for a long time, has been confused with Bothriceps , while the genre Keratobrachyops it could actually be the strict relative of Bothriceps .
