Fucking bullshit that humans only came around when all the cool mega fauna was on it's way out. Stone age people had access to mammoth and I bet they didn't even appreciate it
Blue whales are the largest animals to ever have existed, that we know of. So that's pretty cool.
There is evidence to suggest that stone age people getting to North America caused that megafauna to go extinct.
I can just imagine flying around scanning for other aircraft with these things around. Normally you can’t spot a bird until a second or two, but this would look like a plane from a glance
