User blog comment:Starscream7/Likelihood of Jurassic Park IV/@comment-11047508-20110524071535

almost all this stuff was also on our article Jurassic Park IV (rumours and news). Jack Horner has said that there is no Jurassic Park IV in progress. If JP4 is released in 2012, they should start soon.

But none the less, that wikipedia would be deleted by now if it wasn't based on something.
