Fig. 4A–E . 1982 Hemiscyllium sp. ; Herman 1982: 141 , pl. 2: 4. 1989 Hemiscyllium hermani sp. nov. ; Müller, 1989: 35, pl. 7: 2–7. Material .—28 teeth from the Ce of Stevns Kridtbrud ( MGUH 29839, MGUH 29840, GMV 2012-65 [batch number]) and eight teeth from the Br1 of Kulstirenden ( MGUH 29841, MGUH 29842, MGUH 29843, GMV 2012-66 [batch number]). Description .—Dentition with monognathic heterodonty. Monocuspid teeth with a large crown and a triangular cusp. The cusp is elongated in anterior teeth and short in lateral and posterior teeth. The crown has a pair of prominent shoulders in anterior teeth whereas the shoulders are deflecting in lateral and posterior teeth. The labial face of the crown is flat and smooth and has a semicircular apron in anterior teeth, whereas it is often bifid in lateral and posterior teeth. The crown strongly overhangs the root. The lingual face of the crown is low and convex and may carry some short folds below the shoulders. The root is bilobed with widely diverging lobes. The basal face is flat with a foramen and the lingual face of the root is high with a median protuberance showing a small central foramen. One or several foramina may be present below the crown-root junction on the shoulders. Anterior teeth tend to be more symmetrical than lateral and posterior teeth and some anterior teeth may have small remnants of cusplets on the shoulders. Teeth reaching 1 mm in height and 0.8 mm in width. Remarks .—It is not possible to make an informed comparison between this species and Hemiscyllium daimeriesi ( Herman, 1972 ) due to the rarity and poor illustration of the later. Hemiscyllium bruxelliensi ( Herman and Crochard, 1977 ) can be separated from H. hermani as the former is more massive and has lateral cusplets. Stratigraphic and geographic range .—From Campanian and Maastrichtian (Late Creataceous) of North Germany ( Herman 1982 ; Müller 1989) to Danian (early Paleocene) in Denmark .
