Armadillo's articulated body marking (5)

I believe the answer is:

tatou

'armadillo's' is the definition.
(tatou is a kind of armadillo)

'articulated body marking' is the wordplay.
'articulated' indicates a 'sounds like' (homophone) clue.
'body marking' becomes 'tattoo' (a tattoo is a marking on the body).
'tattoo' is a homophone of 'TATOU'.

(Another definition for tatou that I've seen is " American resident carrying plates".)

I've seen this clue in The Guardian.
