Kind of chip in fossil I conserved (7)
I believe the answer is:
silicon
'kind of chip' is the definition.
'silicon' can be an answer for 'chip' (synonyms). I'm not certain of the 'kind of' bit.
'in fossil i conserved' is the wordplay.
'in' indicates a hidden word.
'SILICON' is hidden in the letters of 'fossil i conserved'.
Can you help me to learn more?
(Other definitions for silicon that I've seen before include "Element used in integrated circuits" , "Electronic material" , "Semi-conducting non-metal" , "Non-metallic element, symbol Si" , "Computer chip element" .)
