Permian tetrapods from the Sahara show climate-controlled endemism in Pangaea
Article Abstract:
A study is carried out on the new fossils from the Upper Permian Moradi Formation of northern Niger, which provides an insight into the faunas that inhabited in low-latitude, xeric environments near the end of the Palaeozoic era. The findings of the study suggest that faunas from the poorly sampled xeric belt differed markedly form well-sampled faunas that dominated tropical-to-temperate zones.

A polydactylous amniote from the Triassic period
Article Abstract:
A preaxial form of polydactyl, in which extra digits are positioned anterior to the first digits, is discovered. The organism has unexpectedly re-emerged in a marine reptile from the Early Triassic period about 242 million years ago. The overall morphology of both the manus and pes closely resemble those of earliest tetrapods.
