Leiorhynchus is an extinct genus of brachiopod belonging to the order Rhynchonellida and family Leiorhynchidae.^[1] Specimens have been found in South America,^[2] North America, and Russia^[3] in beds of middle Devonian^[4] to Mississippian^[3] age (372 to 325 million years old).^[5] The genus may have been adapted to dysaerobic environments, colonizing areas of reduced oxygen concentrations rich in organic matter.^[6] The genus has been used as an index fossil in North America.^[7]
