Anacoracid shark teeth (Chondrichthyes, Vertebrata) from the early Cretaceous Albian sediments of Leighton Buzzard, south-central England
چکیده انگلیسی

The early Cretaceous anacoracid shark Squalicorax primaevus (Dalinkevičius, 1935) is known only from very rare isolated teeth, principally from overseas locations, with only three specimens from UK deposits being registered in a recognized depository. These three teeth, from the Albian Gault clays of Folkestone, are in the collection of the Natural History Museum, London.This short paper describes and illustrates six isolated teeth obtained over a period in excess of twenty years from the Albian Gault exposed in sections northeast of Leighton Buzzard, the first confirmed record of this species occurring in south-central England.
