The Himalayasaurus has not made it into the Jurassic Park film series yet. One reason may be that little is known about this giant reptile, which looks like an overweight dolphin with sharp teeth. In 1972, a Chinese researcher first learned about this sea monster, which has been extinct for about 200 million years. Paleontologists hope to gain new insights from the fossil they have discovered near Lhasa. In that area, the creature is also known as the Tibetosaurus.
