A type of early and middle Neolithic pottery found in the northeast of England, named after the site of Hanging Grimston in what was formerly the East Riding of Yorkshire. Characterized by fine fabrics, good-quality finish, and round-bottomed forms with a carinated profile. In 1974 Isobel Smith suggested that such pots were part of a far wider distribution of carinated vessels found right across the British Isles and she proposed the term Grimston-Lyles Hill ware. These vessels represent the earliest style of pottery found in the British Neolithic, although the term shouldered bowl is now preferred to Grimston-Lyles Hill.
