what would you do?

Ignoring the fact that you ripped off my idea...

I would just accept death.

its not a rip off its a tribiute =)

its not a rip off its a tribiute

Well, I would be fine with that if you said that in the discussion and at least told me before...

blast it in the face with the magnum (three rounds should do, possibly only one) then stomp on the baby's, and smash them with tree branches, and take them for their flesh. Mmm, flesh.

you forgot to mention ho would you take with you and why

Oh, well I'd either take Mr. happy for his gun knowledge, or a clone of myself so that I can have another chance if I mess up.

I would first taunt it by throwing tomatoes at its face and then shoot it with the magnum, however many times I have too and then I would use the flair gun to scare the babies off

I would also take MrHappy for his gun knowledge.

Megaraptor was more around 2.4 meters tall..

But i would kind of just accept it. Maybe try to take out the Allosauroid, but a predator like that is gonna eat your face if it wants to eat your face

make a salad and do a selfie

That would be easy and even possible to achieve.

Not trusting my aim a lot, I should run towards the Stego herd (as I'm a fast runner). and I'd just let the Stegosaurs do their job.

The gun should really be my last resource.

And I don't know who I'd bring. RexFan most likely

Probably do what DinoSteve said, go to the Stegos and only use my gun if I had to and peg everything else at the Megaraptors...(BTW I'm also pretty fast) I would take Mr.Happy, because his gun knowlage...

It's about a one ton predator, and I'm slow, so yeah, one shot to eye should do it. If not, shoot it again in the other eye. If it's not dead, it won't be going after you. If the babies attack, hit them with the flare gun. 

In all honesty, if I was going to an island with dinosaurs just to take pictures, that wouldn't stop me from getting the biggest gun I can legally obtain. 

Burn the island into the sea. ;)

Hmm...Run to the Stegosaurus herd and use them for shelter. Then, I would shoot the flare, leading the Megaraptor to the her. It would then be killed by the Stegosaurus herd.
