This is a Hypacrosaurus paper craft for kids, a genus of duckbill dinosaur similar in appearance to Corythosaurus, the papercraft created by Dover Publications. Hypacrosaurus is most easily distinguished from other hollow-crested duckbills by its tall neural spines and the form of its crest.
The neural spines, which project from the top of the vertebrae, are 5 to 7 times the height of the body of their respective vertebrae in the back, which would have given it a tall back in profile. The skull's hollow crest is like that of Corythosaurus, but is more pointed along its top, not as tall, wider side to side, and has a small bony point at the rear. Unlike other lambeosaurines, the passages for the airways do not form an S-curve in the crest. The animal is estimated to have been around 9.1 meters long (30 feet), and to have weighed up to 4.0 tonnes (4.4 tons).
As with most duckbills, its skeleton is otherwise not particularly remarkable, although some pelvic details are distinctive. Like other duckbills, it was a bipedal/quadrupedal herbivore. The two known species, H. altispinus and H. stebingeri, are not differentiated in the typical method, of unique characteristics, as H. stebingeri was described as transitional between the earlier Lambeosaurus and later Hypacrosaurus. Photographs of an adult H. stebingeri skull show an animal that looks very similar to H. altispinus. For more information please click here.
