Palaeophonus (meaning "ancient killer") is the oldest known genus of scorpions.[2]

This genus is known in the fossil record from the Silurian to the Carboniferous (age range: 428.2 to 314.6 million years ago). Fossils have been found in Europe, the United States, and Canada.[3]
Description
Palaeophonus was virtually identical to modern scorpions. It grew to a lengths of 2.5–3.5 in (64–89 mm).[4] These animals did not have eyes and therefore they were blind.[5]
Until a few decades ago, Palaeophonus, similarly to many other scorpions of the Silurian, was thought to be one of the earliest animals to have conquered the land. In fact, a closer examination of the fossils has determined that these animals possess well-developed gills, very similar to those of contemporary eurypterids (sea scorpions).[6]
