Burrirhynchia leightonensis is a fairly rare species of brachiopod found in the the Shenely limestone beds in Leighton Buzzard, UK. They are quite small in size, between 1.5 to 2 cm in length and were a fauna present during the Cretaceous period, during the time of the deposition of the lower Greensand beds, dating them to around 140 to 100 million years old. Occurrences have also been found in Norfolk. The fossil specimens have been prepped and cleaned, so show no signs of matrix on them and the shape and ribbing of their shells is easily seen, even without magnification. Specimens are supplied in a small polythene bag with a label.
