Durham recovered from a disastrous start to put a dent in Yorkshire's title hopes, reaching the close on day one at Scarborough on 406-6.
Mark Stoneman and Ben Stokes both hit centuries for the visitors in the crucial LV= County Championship fixture against the current leaders in Division One.
Skipper Paul Collingwood also weighed in with an unbeaten 74 as Durham - who sit second in the table themselves and have played a game less - claimed maximum batting points before the end of play.
Such a scenario seemed unlikely when they slipped to 5-2 inside three overs after winning the toss and opting to bat first.
Ryan Sidebottom trapped both Keaton Jennings and Scott Borthwick lbw before the pair had got off the mark during a superb opening spell from the former England left-armer.
However, from then on the day belonged to Durham. Will Smith added 62 for the third wicket before he departed on 20, caught by a diving Kane Williamson in the slips off the bowling of Jack Brooks.
Stokes came out to combine in an alliance worth 128 in 27 overs with Stoneman, who galloped to this third century of the season off 117 balls with 19 fours and that one six.
He eventually departed for 122, caught behind by wicketkeeper Jonny Bairstow to become Sidebottom's 600th victim in first-class cricket.
Stokes reached three figures after tea but having slog-swept Adil Rashid for six just previously, the left-handed all-rounder could only deflect his next attempt at the shot up in the air for Bairstow to pouch. It ended a fine innings of 127 from 160 balls with 17 fours and a six.
His departure also halted a stand of 120 with Collingwood, who by stumps had hit 11 boundaries in his unbeaten knock spanning 144 deliveries.
An attempt to reverse sweep Williamson ended Phil Mustard's entertaining 42 shortly after he had cut the New Zealander's off-spin for four to raise the 400, clinching a fifth batting point in the process.
