Scott Dureau has now scored 59 points for Catalan Dragons this season
Catalan Dragons pulled off the shock of the season so far as they won at Super League leaders Warrington.
The rampant Wolves enjoyed a record-breaking 82-6 win against Harlequins in their last home game a fortnight ago.
But they were stunned by tries from Cyril Stacul, Frederic Vaccari, David Ferriol and Scott Dureau, who ended the afternoon carried off on a stretcher.
Joel Monaghan bagged two tries to take his Wolves tally to seven, while Chris Riley and Richie Myler both crossed.
But Brett Hodgson landed only two kicks out of four with the boot.
After six wins on the spin, it was Warrington's first defeat since the season-opening reverse to Huddersfield at the Millennium Stadium on 13 February.
The Catalans also stunned Tony Smith's side 29-28 in Perpignan last July - but this was an even more unlikely victory.
All three of the Dragons' Super League wins this season have come away from home, but this was by far the biggest, lifting them to ninth in the table.
Dureau scored 10 of the Dragons' points, kicking three goals as well as coming up with the match-winning try 10 minutes from time.
The Aussie scrum-half pounced on a mistake by Myler to race clear 14 minutes from time before adding the crucial conversion.
But, within minutes, the Dragons scrum-half was carried off after being caught by a late tackle from Wolves forward Garreth Carvell.
If you are not at your best you can get beaten by any team in this competition. The opposition outplayed us
Warrington coach Tony Smith
The former Newcastle Knights player required lengthy treatment before being sent for X-rays on his neck.
Warrington, who now lead the table only on points difference from Castleford and Huddersfield, held the advantage for large parts of the game.
But they were never more than one try ahead as the Dragons, who will now spend the week in Manchester before facing champions Wigan at the DW Stadium on Friday night, claimed a major scalp.
The men from Perpignan paid a price with injuries to both Dureau and influential full-back Clint Greenshields, who suffered a dislocated elbow in only the third minute.
Warrington compounded the visitors' early problems by taking the lead five minutes later through Monaghan, the Australian diving over from a Chris Bridge pass to score out wide.
Having eventually begun to settle, Quins were aggrieved when Dureau broke 70 metres from an interception only to be pulled back for an infringement spotted by referee Phil Bentham.
But the French side got themselves back on level terms when Sebastien Raguin found room on the left to send Stacul over in the corner.
Warrington responded by setting up a second opportunity for Monaghan and the winger again made no mistake as he broke through a tackle to touch down, Hodgson converting.
But the Dragons were level at 10-10 by the break when Vaccari broke from halfway and beat Bridge to the line for a try improved by Dureau.
Scott Dureau should be OK, but it is not a good thing to see. They are checking out his neck and let's hope it is not too serious
Catalan Dragons coach Trent Robinson
The Wolves struck again early in the second half when Riley, who had gone close only to knock on moments earlier, was set up by Rhys Evans in the corner.
But Catalans showed their resolve yet again to hit back when Ferriol took a short pass 10 metres out and showed nimble footwork to skip a tackle and power over.
Dureau's goal edged the visitors into the lead for the first time as anxiety started to grow among the home fans.
But a moment of brilliance by Myler put Warrington back ahead just after the hour, the former Salford scrum-half creating a huge gap with a smart dummy after taking a high pass to earn his seventh try of the season.
Hodgson converted but Myler then cost his side at the other end, feebly palming the ball into Dureau's hands from Lee Briers' high kick.
And Dureau took full advantage, racing away for what proved to be the winning try, once he had added the goal.
Dureau's afternoon was then ended prematurely by Carvell. And, although both sides had chances in a frantic and tense finale, the visitors held on.
Warrington coach Tony Smith: "I wouldn't have expected that but they are a good team and have been improving. And it shouldn't be a surprise to anybody.
"If you are not at your best you can get beaten by any team in this competition. And we were far from our best today. The opposition outplayed and out-enthused us.
"Garreth Carvell's tackle was not late. It is only about where contact was made. If he gets him high he deserves whatever punishment."
Catalan Dragons coach Trent Robinson:
"Warrington are an outstanding team. They are as good as any NRL team, with what I have seen them produce in the last seven or eight weeks.
"But you should never write yourself off when you play these teams. We still have a lot of work to do but the effort is what you want to see. There was some heart and soul put in.
"I got told that Scott Dureau should be OK, but it is not a good thing to see. They are checking out his neck and let's hope it is not too serious.
"As for Clint Greenshields, I think that is a bit worse. I am not sure what it means but I know it will be a few weeks at least."
