Former Reds loan midfielder Josh Brownhill's 91st minute equaliser means Barnsley have now set a new club record of 12 home games without a win, surpassing the 11 set under Keith Hill in 2012-2013.
For the second successive season this fixture at Oakwell finished 2-2 with a last minute equaliser - back in October 2016, Adam Hammill also netted in the 91st minute to rescue a 2-2, incidentally that is the last time Hammill has netted for the club and prior to this weekend's matches he had had both the most shots without scoring (50) and created the most chances without registering an assist (44) in the Championship this season.
Brownhill is the THIRD ex Barnsley player to score against the club this season following Conor Hourihane and Josh Scowen. Those goals have cost the Reds three points (one against QPR and two against Bristol City)
Kieffer Moore's seventh minute opener was the earliest Barnsley have scored in a game since the last time they won at Oakwell - the 4th November v Birmingham when Tom Bradshaw netted after just two minutes.
Nine of Barnsley's last 10 goals have been scored by either Moore or Oli McBurnie (3 for Moore, 6 for McBurnie)- Brad Potts finally ended the run with the second against Bristol.
Famara Diedhiou scored his first goal in English football against Barnsley and now his 12th, thus becoming the third opposition player to score in both his club's league meetings with the Reds this season, after Cardiff's Callum Paterson and Millwall's Lee Gregory.
Barnsley scored more than once at Oakwell for the first time since their last home win, way back on the 4th November.
In the Championship they have scored more than once at Oakwell on only five occasions.
Home and away this was only the third time in 26 outings (all competitions) that Barnsley have scored more than once.
Moore both scored and assisted in this game, the first Barnsley player to do this since Harvey Barnes against Sunderland in August.
Barnsley have now won only two of their last 17 league matches against the Robins (D6 L9).
Four of the last six meetings have ended in stalemate and all four have finished 2-2!
There have been 33 goals scored in the past seven meetings (14 for Barnsley, 19 for Bristol)
Indeed Bristol City have scored at least twice in 14 of their last 15 league games against Barnsley (38 goals in total), losing the other 1-0 in September 2012.
For the second season in a row a player scored in both Barnsley/Bristol City meetings, last season was Tammy Abraham, this season Diedhiou.
The Robins are though now winless in 11 away matches in all competitions (D5 L6).
These two sides met on the opening day of the season, Barnsley have not beaten their opening day opponents in either meeting that season since 2012-2013 when they did a double over Middlesbrough - that is their only wins in a season against opening day opponents since 2008-2009, as after losing at QPR on the opening day they defeated them in the return fixture at Oakwell.
After making no goalkeeper changes for 122 games, Barnsley have now changed the man between the sticks four times in 10 games, including in each of the last three.
Jose Morais made a double subsitition in the 61st minute of the game, the fourth time he has made a change in that minute in the last four games.
Barnsley have now played 43 home league games since winning promotion back to the Championship, and won only nine. (W9 D19 L15)
Bristol City had 61% possession in the game, the most an opponent has enjoyed at Oakwell since Fulham (64%) in January.
Eight of Barnsley's 23 shots were on target, their second highest amount at home this season after v Ipswich (10) in the first home game of the season.
Birmingham's 1-0 win over Ipswich on Saturday dropped Barnsley into the relegation zone, two points adrift of safety. Out of the last 54 teams to be in the Championship bottom three at the start of April, 44 have gone on to be relegated and at least two of the three have gone down in every season this century.

Bristol City manager Lee Johnson said:
"I thought it was a resilient point in the end. I didn't think we were at our best.
"I thought it was a difficult game. The pitch, conditions and environment were difficult, and Barnsley worked their socks off, so you have to give them credit.
"I thought we started a little bit poesy. We were a little bit slow to get on the front foot, and that was a little bit disappointing. It's quite difficult to come back from that."
