About Gasosaurus:

The only remains of the obscure but amusingly named Gasosaurus were discovered in 1985 by the employees of a Chinese gas-mining company. From the limited number of fossil remains, adding up to a single partial skeleton, paleontologists believe that Gasosaurus resembled a vastly scaled-down Allosaurus, its fellow (and more famous) theropod, though its arms were a bit longer compared to its overall size. Because so few specimens of Gasosaurus have been identified, it's possible that this dinosaur may have been misclassified--and is in fact a species of Megalosaurus or Kaijiangosaurus.
