The Microflora of the Upper and Lower Estuarine Series of the East Midlands

Abstract

The Upper and Lower Estuarine Series in the East Midlands contain a number of layers of carbonaceous shale or clay and in many cases roots can be seen extending downwards in the underlying deposits. Except for plant-remains these carbonaceous layers are for the most part barren. Samples supplied by Mr. Linsdall Richardson were examined by Professor Harris and found to contain small fossil plants of types which appeared determinable and thus of possible stratigraphic value. Mr. Richardson collected other samples which he sent together with stratigraphic notes; Professor Harris handed me the material for investigation.
