酷東西

趣味知識

Petrustitan was named in 2025, making it one of the newest dinosaur names.3

Its name comes from Greek words for 'stone' and 'giant', because its fossils were found in rocky outcrops near the village of Sânpetru.1

Petrustitan lived during the Maastrichtian age, about 72 to 66 million years ago, right before the dinosaurs went extinct.3

This dinosaur was originally thought to be a species of Magyarosaurus, but scientists later decided it was different enough to get its own genus.1

Petrustitan was a dwarf dinosaur, smaller than many other titanosaurs, because it lived on an island where food was limited.2

Only a few bones of Petrustitan have been found, including a leg bone (fibula) and a shin bone (tibia).1
