In our impression, dinosaurs seem to have long necks. For example, long-necked dinosaurs such as meandering dragons and Mamenxi dragons are very popular in the exhibition of simulated dinosaurs, but the short-necked panlong is an exception. Rare short neck. This should be related to the environment in which it lives and its food.
The short-necked Panosaurus is a prokosaurus dinosaur with a very short neck. It lived in the late Jurassic Argentina. Its specimen was excavated from the eroded surface of river sandstone in the province of Neuquen, Argentina, and is the only known specimen.
When people discovered the short-necked panlong, its joints were still connected. These bones included the spine of 8 necks, 12 backs, and 3 sacral spines. There were also proximal parts of the ribs in the back neck, The distal part of the femur, the proximal part of the left tibia, believes the right intestine. The short-necked Panlong’s skull structure shows that their heads cannot be raised more than 2 meters, their necks are very short, and they are 40% shorter than the necks of other prosauridae. dinosaur. Its short neck makes its branches very unique, forming an independent niche in this order.
The members of the Pterosaurs, including the short-necked Panlong, seem to show signs of shorter neck evolution, including the Pterosaurs living in Africa. The short neck of dinosaurs illustrates their gradual adaptation to low-level plants, and finally evolved into the phenomenon of taking this particular plant as a staple food. The short-necked panlong, which can adapt to plants one to two meters high on the ground, seems to be longer than those with long neck We have a wider selection of plants, which swipe back and forth like lawn mowers in low plant plains.
