Bones Uhle finally found buried in green hill (9)
I believe the answer is:
vertebrae
'bones' is the definition.
(vertebra is a kind of bone)
'uhle finally found buried in green hill' is the wordplay.
'finally' suggests the final letters.
'found buried in' is an insertion indicator.
'green' becomes 'vert' (heraldic term for green).
'hill' becomes 'brae' (Scottish term for a hill).
The final letter of 'uhle' is 'e'.
'vert'+'brae'='vertbrae'
'e' put into 'vertbrae' is 'VERTEBRAE'.
(Other definitions for vertebrae that I've seen before include "Backbone segments" , "Bones of the spinal column" , "Bones of back" , "Bits of skeleton" , "Bony segments of the spinal column" .)
