Although its forelimbs were small

Its discovery in Poland has provided a new perspective on the diversity of fauna during the Late Triassic period and has shown that non-dinosaur reptiles could also reach gigantic sizes and play an important role in the ecosystems of the time

forming a structure highly unusual among theropod dinosaurs

Habitat and distribution: Prestosuchus inhabited areas close to bodies of water

adapted for rapid bipedal locomotion

Spinosaurus aegyptiacus Cuvieronius Although its forelimbs were smallSpinosaurus aegyptiacus was one of the largest theropod dinosaurs to have existed, with an estimated length of between 15 and 18 meters and a weight that could exceed 7 tons.
