Darren Bent’s fourth goal in five games earned a point for Derby and knocked promotion rivals Bournemouth off the top of the Championship.
Matt Ritchie swept in a stylish opener for Bournemouth after Yann Kermorgant played the ball into his path.
But Bent set up forward Tom Ince to equalise on the half-hour mark.
Callum Wilson fired in to give Bournemouth a half-time lead, before Bent – on loan from Aston Villa – scored from a Simon Dawkins cut-back.
Bournemouth showed why they are the country’s top scorers by taking the lead with their first meaningful chance.
Wilson went bursting down the right and his cross was chested down by Kermorgant for Ritchie to send a cushioned volley beyond Lee Grant and into the bottom right corner.
It was a blow for Derby, who then lost top scorer Chris Martin to an injury, and could have gone further behind as Wilson seized on a poor header from Richard Keogh and steered his shot wide from the edge of the penalty area.
Home goalkeeper Artur Boruc made a terrific save to stop a near-post volley from Bent – on for the injured Martin.
But Derby hit back as Ince finished emphatically from 12 yards after the busy Bent had robbed Bournemouth defender Steve Cook by the corner flag and pulled back a cross.
Wilson restored Bournemouth’s advantage in the final minute of the half, ripping a right-foot shot across Grant into the top corner after Kermorgant had worked tirelessly to chase a long punt up field and keep the ball in play.
The second half was not as frenetic as the first but it required an excellent block by Bournemouth captain Tommy Elphick to deny Ince a second after the winger wriggled past two defenders.
Bent silenced the home fans in the 67th minute to earn a point – again showing Aston Villa boss Paul Lambert what he is missing by sending him on loan.
