Leptophractus

Leptophractus is an extinct genus of embolomere described from an Upper Carboniferous coal mine at Linton, Ohio.^[1][2] It probably represents a young growth interval, and is therefore a synonym, of Anthracosaurus lancifer, which was described much earlier from the same deposit at Linton.^[3]
