Period when Julius Caesar captures Russia in revolt (8)
I believe the answer is:
jurassic
'period' is the definition.
(Jurassic period is an example)
'julius caesar captures russia in revolt' is the wordplay.
'julius caesar' becomes 'jc' (this might be a standard abbreviation I've not previously seen).
'captures' indicates putting letters inside.
'in revolt' is an anagram indicator.
'russia' is an anagram of 'urassi'.
'jc' enclosing 'urassi' is 'JURASSIC'.
'when' acts as a link.
Can you help me to learn more?
(Other definitions for jurassic that I've seen before include "Of the dinosaur period" , "Between Triassic and Cretaceous" , "'...Park' was book/film about dinosaurs" , "From the time of the dinosaurs (as movie park)" , "Of the dinosaur era" .)
