Clarke was fined for warning Anderson in Brisbane to "get ready for a broken f---ing arm" as the England pacer readied himself to face Mitchell Johnson.
The animosity started from an incident in the dressing room in Adelaide in 2006-07 in which Anderson hit Clarke with a batsman's pad after being egged on by the Australian's teammate Damien Martyn.
Former Test batsman Dean Jones, who was present in the Australian dressing room, was surprised over the friendly atmosphere after England's captain Alastair Cook came in with his team.
The Sydney Morning Herald quoted Jones, as saying that fellow openers Michael Carberry and Chris Rogers were speaking about their game, Steve Smith and Joe Root were talking and Anderson was speaking to Clarke.
He further added that coaches Andy Flower was speaking to Darren Lehmann and both the teams were together for three hours.
Australian all-rounder Shane Watson said the England players were gracious in defeat.
