Bony lab found in the ancient city (7)
I believe the answer is:
babylon
'bony lab found in the ancient city' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for babylon that I've seen before include "Ancient capital" , "Ancient city on Euphrates once noted for sin and wickedness" , "Ancient city on Euphrates noted for luxury and wickedness" , "City noted for wealth and wickedness in Bible" , "Ancient ruined city in modern Iraq" .)
