Animal died, one with no name (3)
I believe the answer is:
doe
'animal' is the definition.
(doe is a kind of animal)
'died one with no name' is the wordplay.
'died' becomes 'd'.
'with no' suggests deleting specific letters.
'name' becomes 'n' (common abbreviation e.g. on forms).
'one' with 'n' taken away is 'oe'.
'd'+'oe'='DOE'
(Other definitions for doe that I've seen before include "A female deet" , "Female hare" , "She eats vegetarian food" , "Rabbit, perhaps" , "Mummy rabbit" .)
