Excursion to Upware, May 10th 1914. The Corallian of Upware is of interest as another phase of a very variable series which occurs between the Oxford and Kim[m]eridge Clays. It is referred to as the Tetworth Clay by Prof. Sedgwick but afterwards as the Ampthill Clay from a locality in which it was better seen. It does not appear to have any fossils peculiar to it but those of the Upper and Lower Series, that is of the Kim[m]eridge and Oxford Clays overlap and are commingled in it. The Tetworth Clay probably represents an age during which varying conditions favourable to the formation of limestones recurred here and there in the district, and at Upware these were characterised by the growth on an immense number and variety of corals (Hughes).
