Chalky resolved English court case (10)

Ross

I believe the answer is:

cretaceous

'chalky' is the definition.
(thesaurus)

'resolved english court case' is the wordplay.
'resolved' is an anagram indicator.
'english' becomes 'e' (abbreviation).
'e'+'court'+'case'='ecourtcase'
'ecourtcase' anagrammed gives 'CRETACEOUS'.

(Other definitions for cretaceous that I've seen before include "of chalk" , "Chalky" .)

I've seen this clue in The Independent.
