Classification: Chordata, Reptilia, Dinosauria, Saurischia, Sauropodomorpha, Sauropoda, Lessemsauridae.
Species: I. prima (type)
Size: Roughly about 7.5 meters long for holotype individual.
Known locations: Argentina - Quebrada del Barro Formation.
Time period: Norian/Rhaetian of the Triassic.
Fossil representation: Partial post cranial remains.
in the late Triassic, Ingentia is a genus of sauropod
already shows thickening of bones and a growth to a large stocky size,
a foreshadowing of the huge sizes that sauropod dinosaurs would attain
in the Jurassic. Since being named Ingentia is
regarded as being
similar in form to other genera such as Lessemsaurus,
hence the inclusion of Ingentia within the
Lessemsauridae group of sauropod dinosaurs. Other dinosaurs likely
around at the same time and location as Ingentia
and the small theropod Lucianovenator.
