kinda hard to choose. Mammoths and Tasmanian tigers have already been mentioned, and I love them. but the list of awesome animals doesn't stop there. Moa, megatheriums, woolly rhinos, hemicyons (half-dog, half-bear mammals)…
wait, I know who I'd bring back. the Paraceratherium aka Baluchiterium aka Indricotherium. one of the largest terrestrial mammals ever. as a kid, I loved seeing this critter pop up in books I was reading. I thought they were a prehistoric elephant/giraffe hybrid, but they're actually tall, hornless rhinos XD
Ah screw it, I guess we can bring back some recently extinct animals too if we really want! I'd bring back the Sloth Lemur, two of my favourite animals combined would've been awesome! (technically they really weren't that closely related to Sloths, but they were cute anyway and I love the name!)

I am that person who wants giant scorpions, hellish sea creatures and monster millipedes running around.
Bring back giant spiders while we're at it as well.
It's weird to think that those creatures lived on the same planet as us, they look like randomly generated creatures from Spore. (I had no idea they were so huge though, wow. o_o)
I'd maybe bring back Neanderthals? Apparently they were stronger than Homo Sapiens, and they actually developed a lot of the same tools and rituals that "we" did. Although, their brains were optimized for controlling vision and balance, so they weren't as good at socializing. Idk how much of that is pop science or whatever, but it would be interesting to see them revived into the modern day.
Also I'd bring back Sid the Sloth from Ice Age. Before anyone says that he's a fictional character, there's actually a growing consensus among scientists that he was a real figure from prehistoric times. I'm not trying to force my opinions on anyone, but here's some evidence for your consideration.
This is an image of a cave painting, which depicts Sid. You can tell that it's him because of his distinctive eyes. Could it be a coincidence? Maybe. But maybe not? I'll leave this on an open-ended note: it's for you to decide. Personally, I'm convinced that he was real.
Working on a science-fiction webcomic. ETA: October November
I love how everyone mentioned different animals. so many amazing creatures :D
and wow that bird is just... the best thing I ever saw since the LotR/Hobbit giant eagles.

could Sid be mankind's first recorded character?
actually, think about it... prehistoric people probably created a ton of characters we don't even know about. folkloric figures, animal gods, that kind of stuff. some of those cave paintings probably showed legends and conjectures based on what they saw outside.
