Possible carving first noted during surveys by the CSI: Rombalds Moor project in 2011 and referenced ‘Green Crag 12a’ on ERA. The team describe: ‘To N is a well defined rhomboid depression with sharp edge to E and contains a trace fossil to base of depression along the N edge. Approx. 2cm from N edge of the rhomboid depression is a 1cm diameter cup-like depression with a faint incomplete narrow ring 3mm wide and 4cm in diameter. Whilst the ring appears to be a natural combination of both trace fossil / eroded mineralisation, the central position of the small cup-like depression within the ring, raises the possibility of it being artificial, although this is doubtful.’

This model just shows the main cup and was created from 6 stereo pairs captured by David Spencer (CSI Team) in November 2011. The imagery forms part of the HLF funded CSI: Rombalds Moor / Watershed Landscape Project archive.
