A last-second goal earned Barnsley an unlikely point at league leaders Cardiff.
Tomasz Cywka's strike deflected off Stephen Foster and went past David Marshall five minutes into injury time. The referee was booed off the pitch at the final whistle as Cardiff's players felt he should have ended the game before Barnsley's late comeback.
The hosts dominated the first half and Craig Bellamy hit the post before Luke Steele made a fine save, diving to his right after a Jordon Mutch drive.
After the break, centre-half Ben Turner poked home a Kim Bo-Kyung corner to give the hosts the lead.
Barnsley rarely threatened throughout the game, although Bobby Hassell missed a great chance when his back post header went narrowly wide.
