A "new" dinosaur may sound like a contradiction, but that's what alert researchers at the State Museum of Pennsylvania in Harrisburg identified on Tuesday.
Kevin Dermody, a fossil preparer and museum volunteer, found the skull of what is now being called Daemonosaurus chauliodus.
"Daemonosaurus" is derived from the Greek words "daimon," or evil spirit and "sauros," lizard or reptile. "Chauliodous," or buck-toothed, refers to its front teeth.
The State Historical and Museum Commission said that museum experts in 2004 realized the specimen from the late Triassic period was something new.
The dinosaur's remains were previously in a large mudstone block from New Mexico with other fossils, which was on loan at the State Museum from Carnegie Museum of Natural History.
The fossil was displayed at State Museum's "dino lab" exhibit, which allows visitors to watch a technician uncover prehistoric remains.
Foloowing the discovery, the Carnegie museum removed the specimen and forwarded it to the Smithsonian's National Museum of Natural History.
Confirmation findings were published last month in the scholarly journal Proceedings of the Royal Society B.
