Liang Long lived in the western part of North America at the end of Jurassic, from1500,000 years ago to1470,000 years ago. The longest individual can exceed 30 meters and weigh about 10 ton. Noses are above the eyes. Their necks can't be lifted, and they should be used to expand the eating area in situ.
Extended data
Appearance characteristics:
Liang Long's head is longer than other sauropods, his nostrils are close to his eyes and his teeth are short. He is a herbivore. According to computer simulation, Liang Long species can easily wave their long tails and make a huge noise of about 200 decibels. Maybe they use this way to scare away predators who attack them. Some Liang Long fossils have broken bones at the ends, which supports this speculation.
As the longest-lived creature on the earth, the dinosaurs of this family only lived on the Jurassic earth. With the arrival of Cretaceous, some plants evolved and withdrew, which made the dragon-footed dinosaurs lose their competitiveness and become an early extinct group in the dinosaur family.
It is worth mentioning that some foreign researchers believe that many original pictures of Liang Long in science fiction movies or popular science books are often painted with Liang Long's neck held high. This repair method does not take into account Liang Long's huge neck structure, that is, the neck is low and flat.
