I have been on a Walt Disney World ride that has an Alioramus in it. It's not really new.. While it is true that the genus Alioramus, which lived about 70 million years ago in what is now Mongolia, was first described in 1976 by Russian paleontologist Sergei Kurzanov, it was only known from an incomplete skull.
Like any other muscles in the body, your abdominal muscles can have spasms that occur as a result of muscle strain during heavy use or overuse, fatigue, dehydration, and alcohol or drug use. Abdominal muscle strain is a common injury among athletes and can cause muscle spasms.
A spasm may be a muscle contraction caused by abnormal nerve stimulation or by abnormal activity of the muscle itself. A series of spasms, or permanent spasms, is called a spasmism. A spasm may lead to muscle strains or tears in tendons and ligaments if the force of the spasm exceeds the tensile strength of the underlying connective tissue.
