Brontoscorpio is an extinct genus of possible scorpion that lived in the Early Devonian. Remains of the only known species, Brontoscorpio anglicus, were discovered in the St. Maughan's Formation, Lochkovian-aged (previously also considered as late Silurian) sandstone from Trimpley, Worcestershire.

==Taxonomic history== The species was described on the basis of an incomplete single free finger of a right pedipalp (In31405), almost long. The complete animal is estimated to have been long for females and long for males, possibly making Brontoscorpio one of the largest known scorpions. The species is characterized by the presence of single condyle and row of thick tubercles on the pedipalp free finger. However, its identity as a scorpion should be treated with caution due to the fragmentary known material of Brontoscorpio and the fact that chelate appendages are also found in other groups of arthropods, and Braddy (2024) suggested that Brontoscorpio might represent a dactylus of a crustacean instead.
