Time sorted out a crisis related to old age (8)
I believe the answer is:
triassic
'related to old age' is the definition.
I can't judge whether this definition defines the answer.
'time sorted out a crisis' is the wordplay.
'time' becomes 't' (abbreviation).
'sorted out' indicates an anagram.
'a'+'crisis'='acrisis'
'acrisis' is an anagram of 'riassic'.
't'+'riassic'='TRIASSIC'
Can you help me to learn more?
(Other definitions for triassic that I've seen before include "It came between Permian and Jurassic" , "Relating to the time of the first dinosaurs" , "Of the period when dinosaurs first appeared" , "Time between Permian and Jurassic; at crisis (anag.)" , "millions of years behind a Neanderthal!" .)
