Brachiopods were reported, as ‘Lingula’, from Anisian (early Mid-Triassic) deposits of the Tarporley Siltstone Formation (Mercia Mudstone Group) in Nottinghamshire in 1955, and from the Helsby Sandstone Formation (Sherwood Sandstone Group) in a borehole in Oxfordshire in 1975. Burrows (Lingulichnus) attributed to this organism were reported from the Tarporley Siltstone in Cheshire in 1981. These records are evidence of marine influence in the depositional environments of those formations.
