Sakamena is also the name of a Permian sedimentary geological formation that has yielded many vertebrate fossil, including Triadobatrachus (the first lissamphibian[1]), Claudiosaurus, one of the first aquatic reptiles,[2] and the Coelurosauravus, the first gliding reptile.[3][4][5]
Sakamena is also the name of a coal field that lies near the Sakoa coal field. Both the Sakamena and Sakoa coal fields are under appraisal and development by Madagascar Consolidated Mining, a subsidiary of Red Island Minerals, a company founded by Sam Malin. Other coal fields adjacent to the Sakamena region include the Ianapera, Imaloto and Vohibory fields.
