Fun facts

Nullotitan was named in 2019, making it a relatively new dinosaur discovery.1

Its fossils were found near the famous Perito Moreno Glacier, which inspired its species name 'glaciaris'.1

The first bone of Nullotitan was actually collected back in 1981 by José Bonaparte, but it was not named until decades later.3

Nullotitan lived alongside the ornithopod dinosaur Isasicursor and the giant megaraptorid Maip.1

Scientists think Nullotitan was a lithostrotian titanosaur, a group of sauropods with bony plates in their skin.2

The fossils of Nullotitan were found broken and scattered over a large area, suggesting the carcass was disturbed after death.3

For dino experts

Scientific name: Nullotitan
Named by: Novas et al. 20195
Group: Long-necks
Family / clade: Lithostrotia5
Classification: Sauropodomorpha > Sauropoda > Titanosauria > Macronaria5
Age of the rocks: 72 to 66 million years (Maastrichtian)5
Rock formations: Chorrillo5
Countries: Argentina5
Fossil records: 3 in the Paleobiology Database5
Discovery: Nullotitan was named by Fernando Novas and colleagues in 2019. The first fossil, a neck bone, was found by geologist Francisco Nullo in 1981, but the full description came later.1
Still debated: Scientists are not sure exactly how big Nullotitan grew, because only a partial skeleton has been found. The length is estimated by comparing it to more complete titanosaurs.3
