Shaved dromedary arrived (4)
I believe the answer is:
came
'arrived' is the definition.
(come can mean to appear or arrive)
'shaved dromedary' is the wordplay.
'shaved' means to remove the last letter.
'dromedary' becomes 'camel' (I've seen this in another clue).
'camel' with its final letter removed is 'CAME'.
(Other definitions for came that I've seen before include "Arrived" , "Appeared" .)
