Diceratosaurus is an extinct genus of nectridean tetrapodomorphs within the family Diplocaulidae. Fossils of Diceratosaurus were first described by Edward Drinker Cope in 1874.{{cite journal |last=Cope |first=E.

The mine was situated in the village of Linton, which became obscure soon after operations were completed and the mine closed in 1921.{{cite journal |last=Hook |first=R.
