Ingentia (meaning: the giant) is a genus of sauropodomorph dinosaur. Described in July 2018, it has completely changed palaeontologists' understanding of when gigantism in dinosaur species first evolved.[1][2][3]

The discovery of this genus, confirmed the thesis that the larger species of prosauropod dinosaurs have evolved in the early to the late Triassic.[4][5][6]


The type species Ingetia prima; named by Apaldetti; 2018, the name meaning "the first to be huge" in Latin language. Ingentia estimated to grew up as much as nine tonnes in weight, making it the largest known prosauropod ever; and the biggest dinosaur in the entire Triassic period; three times bigger than the previous largest genus. Length estimates are between 26 to 33 feet (7.9 - 10 meters). The species had a herbivorous diet like all known species of sauropodomorphs; and it was, presumably, able to stand between its hind legs for a short period of time similar to its cousin genus, Plateosaurus.[7][8][9][10]

Ingentia prima lived during the late Triassic, from about 205 million to 210 million years ago, in what is now Argentina. Note its avian-like respiratory system that has cervical air sacs (green) and its lungs (brown).[11][12]
