[2] His interest in geology began when he found a fossil on the Clent Hills.
His most important work was on the Old Red Sandstone, which was then believed to be barren of fossils.
His work on this in Shropshire and elsewhere, particularly at Earnstrey east of Brown Clee Hill led to him discovering fossils of a fish, named Corvaspis Kingi.
His later papers included 'The Downtonian and Dittonian Strata of Great Britain and North-Western Europe' Quarterly Journal of the Geological Society 90 (1934), pp. 526ff.
In 1924 he was awarded the Lyell Medal by the Geological Society of London.
