Over 300 million years ago, today’s Pacific Ocean was covering a large area of SW South-america. A team of paleontologists travels that region in order to understand its climate and fauna, as well as the changes that affected it, during that time.
The research article conducted by a multidisciplinary team, that took four years, is published in the scientific journal Proceedings of the Royal Society of London (United Kingdom). Scientists have given an official name to the new species: Patagotitan mayorum, which gives information that helps understanding key aspects on the evolution of titanosaur sauropods.
The scientific Staff of the Existing Plants area in Mef has been working for several years searching for crops to the production of oils, resins, fatty acids and gums of industrial use that would adapt to the arid conditions in this region.
About 300 million years ago the Andes hadn´t risen yet, what allowed the current Pacific Ocean cover a great part of West Patagonia. The Sierra de Tepuel area, located 100 km southeast from Esquel city (West of Chubut) is especially rich in fossils from that time, which represents part of the Carboniferous and Permian Periods and has a marine record spanning a continuous temporal interval of practically 70 millions of years. This uninterrupted record of so many millions of years, along with the great amount and diversity of fossils found make this site of great importance for researchers who study this particular time lapse.
