The "funpark" missions are a Jurassic Park themed minicampaign of five missions added to Command & Conquer with The Covert Operations expansion pack. The actual mission files have been in the game from the very first release, but the "funpark" command line parameter that unlocks them in the game wasn't added until DOS C&C v1.20, the game version that came with The Covert Operations, and the expansion pack also contains an update of the dinosaur missions.
