Wheathampstead skull (monument)

My daily walk took me through the churchyard of St Helen's, Wheathampstead, where the sun was perfect for photographing this tombstone near the south porch. There is another stone I have my eye on but a pesky tree blocks the light. Where's my chainsaw...

Postscript. This is the tomb of Nicholas Coningsbye recorded as having been buried in January 1738 in the parish registry. The volume of Hertfordshire Monumental Inscriptions for Wheathampstead records nothing about this stone but parts of the text are clearly legible including the name.
