An international team of paleontologists has found several amphibian species and a reptile that lived 278 million years ago
Now we finally have information about what kinds of animals were present in areas farther to the south, and their similarities and differences to the animals living near the equator,” said Dr Kenneth Angielczyk from the Field Museum of Natural History,
One of the new dvinosaur species, Timonya annae, was a small, fully aquatic amphibian with fangs and gills, looking something like a cross between a modern Mexican salamander and an eel.
The other new species is Procuhy nazarienis, an amphibian whose name in the Timbira language of its Brazilian homeland means ‘fire frog.’In the same region as where the fossils of Timonya annae and Procuhy nazarienis were uncovered, the palenontologists also discovered fossils of Captorhinus aguti and a collie-sized amphibian whose closest relatives lived in later times in southern Africa.
The fact that these species have also been found in modern-day Brazil helps paleontologists paint a picture of the ways that animals spread during the Permian and how they colonized new areas.
Exploration in understudied areas, such as northeastern Brazil, gives us a snapshot of life elsewhere that we can use for comparisons,” he said.“In turn, we can see which animals were dispersing into new areas, particularly as an ice age was ending in the southern continents and environmental conditions were becoming more favorable for reptiles and amphibians.”
