In the Early Permian, tetrapods (the four-limbed vertebrates) seemed to be in full bloom. Although the group’s living members include amphibians, birds, reptiles, and mammals, the earliest tetrapods resembled today’s salamanders. Despite the abundance of trackway and fragmentary fossils, the diversity of tetrapods in the ancient continent of Gondwana around this time remained unknown.
A formation known as Pedra de Fogo, the Parnaíba Basin of northeastern Brazil records a snapshot of life in the southern supercontinent. One study conducted by an international team attempted to describe multiple specimens from this area. Two of the n
Notable specimens belong to a group called Dvinosauria, a subgroup of the early amphibian group Temnospondyli. Timona anneae is said to resemble a mix between a salamander and an eel, while Procuhy nazariensis is likely related but too fragmentary to determine its exact appearance. Other indeterminate Temnospondyli remains from the family Rhinesuchidae were found to be much older than their previously known relatives found in South Africa.
