The River Erewash as it leaves the Erewash Valley Coalfield passes southwards through a gap in the Triassic scarp. On either side of the river, as it enters the gap, lie the twin settlements of Stapleford and Sandi-acre. The former spreads along the river flat at the foot of the scarp where this merges into the river bluff known as “Bob’s Rock”. At this point there is a quarry in the Bunter Sandstone situated behind St. John’s School. In the autumn of 1939 Mr. C. R. Vickers, the head master, drew my attention to the fact that the quarrymen were finding a number of bones in the sandstone. Though rather sceptical about the authenticity of such a find in the Bunter I visited the quarry. After inspecting the bones I was shown the precise spot where they occurred. This lay in the top part of the quarry face which was about 40 feet high. As looked at from the floor the sand at that spot was seen to fill a hole descending into the rock to a depth of about 7 feet and having a width, in its lower part, of about 2 feet.
