Analysis of the bones showed that the individuals not reached its maximum size. The researchers suggest that they could die of thirst – perhaps together with other herbivorous dinosaurs Patagotitan mayorum came to drink to the lake, which dried up during periods of drought, and animals died from its shores. And dinosaurs are scavengers, eating the remains of dead animals, their bones trampled deep into the clay that contributed to the sound.

Patagotitan mayorum, like some other discovered in Argentina the species belongs to the group of titanosaurs. In the Jurassic and Cretaceous periods titanosaurs lived on all continents except Antarctica.
