No offence to Robin Williams, but I think having a living specimen of an ancient species who lived millions of years ago might help scientists advance evolutionary biology by a lot

Or maybe not, but look at that little guy, he's so cute :D

I'm not sure I want Williams to see the Trump era of America. I think it might have killed him again.

I was hoping one of them would be Steve Irwin... 🙁

If Mr. Williams was unhappy I would not bring him back to this world we have now.

I would want to make heaven on earth before I woke anyone ... except my pets.

No one else wants to bring back anomalocaris so we can get some payback?

Would Anomalocaris actually do well in the modern world. I feel like they probably wouldn't do so well in the modern ecosystems of much more evolved marine creatures. Would get out-competed very quickly, and likely face plenty of other challenges. Being out-competed is likely the reason they went extinct in the first place.

Robin Williams, but he comes back fully cured of everything and he gets to live a full life happy.
