Ingentia was a remarkable early sauropod dinosaur that lived during the Late Triassic period, around 227 million years ago, in what is now northwestern Argentina. This groundbreaking discovery, described in 2018, revolutionised our understanding of sauropod evolution by showing that these massive herbivores achieved enormous sizes much earlier than previously thought.
As one of the first truly gigantic sauropods, Ingentia measured approximately 8 metres in length and stood about 3 metres tall at the hip, weighing an estimated 4 tonnes. Despite being an early member of the sauropod lineage, it already displayed the characteristic long neck and tail that would become hallmarks of later giants like Brontosaurus and Diplodocus. Its sturdy build and powerful limbs were well-adapted for supporting its considerable bulk whilst browsing on the abundant plant life of Triassic Argentina.
Like other sauropods, Ingentia was a herbivore that used its elongated neck to reach vegetation that other dinosaurs couldn't access. Its teeth were designed for stripping leaves rather than chewing, suggesting it swallowed plant material whole and relied on stones in its stomach to help break down tough fibres. This feeding strategy would prove incredibly successful, allowing sauropods to become the largest land animals ever to walk the Earth.
The discovery of Ingentia, along with its close relative Lessemsaurus, has provided crucial insights into the rapid evolutionary growth that occurred during the Triassic period, showing that the age of giants began much earlier than scientists had previously realised.
Ingentia possessed the classic sauropod body plan with a long neck and tail, but was distinguished by its relatively early evolutionary position and impressive size for a Triassic dinosaur. Its robust limb bones and vertebrae show adaptations for supporting great weight, marking it as one of the first truly massive land animals.
Ingentia likely lived in herds, using its long neck to browse on tall conifers and ferns that dominated Triassic landscapes. As a massive herbivore, it would have spent most of its time feeding to fuel its enormous body, potentially migrating seasonally to follow food sources.
Ingentia was first described by Cecilia Apaldetti and team in 2018. The original fossils were discovered at Quebrada del Barro Formation, northwestern Argentina.
