It was named "Ingentia Prima" and it was 3 times bigger than its similars of the Triasic Period.

Argentine researchers presented Ingentia Prima, the first giant dinosaur that inhabited the planet more than 200 million years ago. The discovery was made at the Balde de Leyes deposit, southeast of the province of San Juan. And it revolutionized the existing theories about when dinosaurs started to become gigantic.
According to a study published Monday in the journal Nature Ecology and Evolution and released by the CTyS Scientific Outreach Agency of the University of La Matanza, the species is between 237 and 201 million years old and is among the first giant sauropods. With a weight of ten tons and 8 to 10 meters long, it is about three times the size of the largest dinosaurs of its period, the Triassic.
About the moment of the unexpected discovery, in May 2015, in the Balde de Leyes -one of the richest places in "Triassic levels" after The Valley of the Moon-, the archeologist Cecilia Apaldetti (36) confesses that when they saw the first bones, half-buried in the bushes , they linked them "to a cow" because they were big and white: "But as we were noticing their size, we began to prime, the heart was coming out of my mouth ... and we said 'This is a dino, this it's going to have to talk! 'And well, I was not wrong. "
Ingentia Prima, which in Latin means the "first immense", is a species 30 million years older than its cousins the titanosaurs, "a fantastic finding that modifies the ideas we had about how these creatures, with traits we did not know about No other species, made to be giants if they were not yet anatomically prepared to be, this dinosaur hit the spurt in an unthinkable time, it's an advance, no doubt.
