On a new Nodosaurid from Ninghsia

Pp. 34, (3); 3 full page photo-plates, each with descriptive leaf of text, 18 text-figures. Original printed gray wrappers, 4to. Palaeontologia Sinica, series C, volume XI, fascicle 1. This is the first description of Pinacosaurus ("the plank lizard"), a new genus of medium-sized ankylosaur dinosaurs that lived from the late Santonian to the late Campanian stages of the late Cretaceous Period (roughly 80-75 million years ago), in Mongolia and China. This type specimen is from Ningxia (Ninghsia), China. Pinacosaurus had between two and five additional holes near each nostril, the function of which is not well understood. Pinacosaurus was a lightly built, medium-sized ankylosaur that reached a length of 5 meters (about 16 feet). Like all ankylosaurids, it had a bony club at the end of its tail which it used as a defensive weapon against predators such as Velociraptor (adapted from Wiki). Old oval ink stamp on the rear wrapper and last page of text, small (one-half inch wide) sticker on the spine, no other ownership marks and few signs of use. Rare work seldom offered.
