Large rectangles span length and width measurements obtained by Gingerich (19776) from Euzet. Symbols solid on left = M\ on right = M2 and completely solid = M3; outline symbols = M1'2. Data for Lacey's Farm Quarry from Insole (1972), for Ehrenstein 1A from Schmidt-Kittler (19716) and for the Phosphorites from a cast. Measurements in millimetres. Lines join teeth of one individual. appear to occur together at three further localities: 1, Ehrenstein 1A (see Text-fig. 26 and Schmidt-Kittler's (1971b) upper molar measurements); 2, the lignite bed in the Headon Hill Limestone (the type locality of L. stintoni), where a large M3 (M20204) has been found (see Text-fig. 26); and 3, the Lower Headon Beds, where L. magnus occurs at Hordle Cliff and a much smaller incomplete M1/2 from HH2 at Headon Hill. Insole (1972: 204-205, pi. 7, fig. 2) recorded as M1/2, small enough to belong to L. stintoni, from the Osborne Beds of Lacey's Farm Quarry, Isle of Wight, as A. magnus (see Text-fig. 26). An even smaller M1/2 has been found in the post-Grande Coupure Lower Hamstead Beds of Bouldnor Cliff ( Ford private collection). Acquisition of a lower molar metastylid (Text-fig. 43) appears to have stratigraphical impor- tance (see below). Its variable occurrence in Leptadapis specimens from the Quercy Phosphor- ites housed in the BM(NH) seemed to have
