Spinophorosaurus

Spinophorosaurus, meaning “spine-bearing lizard,” is a genus of early sauropod dinosaur from the Mid Jurassic Period or possibly earlier. It was discovered in a rock formation in Niger, belonging to the lower part of the Irhazer Group. The specimen is unusual for having spiked ectoderms, probably from the tail, similar to the famed thagomizer found in stegosaurs. The type specimen, S. nigerensis, was described by Remes et al. in 2009.
