Okay. The Hammond Foundation sent out space missions to find more species that are like dinosaurs and they found the Clannfears then they built research bases at some of the dig sites which is why hopefully we'll be able to find Clannfear dna at the dig sites.
It's difficult to find digsites for these creatures due to the lack of Oblivion gates opening up. On a serious note, we're focused on dinosaurs and creatures from or inspired by the Jurassic World franchise. We have no plans to introduce non Jurassic World franchise creations into the game.
I had to look them up, and they are the dumbest looking things I've ever seen. They're like if the Alien Queen was spliced with a Skeksis. Why would anyone even want this?
