Saichania was one of the most well protected of all the armored dinosaurs. Even its stomach or underside was covered with bony platings.
Saichania had a large, heavy hammer tail, and was covered with sharp spikes which protected it against enemies. The skull of Saichania reveals unusual breathing passageways that perhaps gave it a powerful sense of smell. This would have helped to alert it to the presence of dangerous predators.
Saichania was discovered in the Gobi Desert in 1971, and was named by Teresa Maryanska in 1977.
