Pinacosaurus

Pinacosaurus is a genus of armored dinosaur that lived during the Late Cretaceous period, about 75-71 million years ago. It was a herbivore that belonged to the ankylosaurid family, a group of dinosaurs known for their heavily armored bodies and club-like tails. Pinacosaurus was a medium-sized dinosaur, measuring about 10-13 feet in length and weighing about 1 ton. It had a small head with a beaked mouth, and its body was covered in bony plates and spikes, which likely served as protection against predators. It had a distinctive feature in the form of a row of large, triangular plates running down its spine, which may have been used for display. Pinacosaurus likely moved slowly due to its armored body and may have used its powerful tail as a weapon. It is known from fossil remains found in present-day Mongolia and China.
