Other lithologies including sandstones, siltstones and chert occur within the group. The Group is subdivided into numerous formations, some of which previously enjoyed group status. In stratigraphic order (uppermost/youngest at top), these are:
* Bowland Shale Formation (mudstone and siltstone)
* Pendleside Limestone Formation (interbedded limestone and mudstone, conglomerate)
* Hodderense Limestone Formation
* Hodder Mudstone Formation (limestone and mudstone) The Craven Group unconformably overlies the Bowland High Group and elsewhere the Clwyd Limestone Group. It is succeeded (overlain) by the Millstone Grit Group
