When did the formal description and scientific confirmation of the species Patagotitan mayorum occur?
Answer
In 2017
While the discovery phase began serendipitously in 2012 when a farm worker noticed the large bone fragment, the official recognition and scientific validation of the new species took several years of careful excavation, preparation, and analysis. The formal description of *Patagotitan mayorum* was published in 2017. This publication officially cemented its status among the known largest dinosaurs, confirming the findings derived from the monumental excavation effort conducted in the Chubut Province.
