Extinct animal may still make a raid on us (8)
I believe the answer is:
dinosaur
'extinct animal' is the definition.
(I've seen this in another clue)
'make a raid on us' is the wordplay.
'make' is an anagram indicator.
'raid'+'on'+'us'='raidonus'
'raidonus' is an anagram of 'DINOSAUR'.
'may still' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for dinosaur that I've seen before include "Extinct beast" , "square figure!" , "Extinct terrestrial reptile" , "Out of date person or thing" , "I adorn US with this old creature" .)
