Good idea, like a park of something? The most difficult part would be naming it. You could go for something like Cretaceus Park, but it doesn't sound too good.

Billy's Cloneasaurus Park

Nailed it!

Not all megafauna are herd animals on the scale of American buffalo. Others were limited to smaller areas or less numerous to begin with, and the ones that survive are probably those that started off most numerous. African elephants are hanging on by a thread, relative to their original number they're down something like 98%.

Africa is also _huge_ - around four times the size of the entire continental USA - and suffered perhaps less during the Ice Ages than Northern America or Eurasia, where megafauna would have been squeezed by both the ice - and associated climate changes further south - and a hungry and increasingly innovative human population.

Consider that African megafauna have co-existed with early hominids and eventually humans for millions of years. They may have simply adapted to human predation successfully enough to survive, as one factor. Whereas in North America and elsewhere you have th…

Right, we're a native species to Africa, so its whole ecosystem evolved with us. I think of this when I hear about "poachers" killing animals in African nature reserves. How often is that hunter gatherers who been there for thousands of years, and whose hunting is/was really part of the ecosystem?

Hunter gatherers who are killing Rhinos only to sell their grounded horns to some idiots in China/etc.?

Oh, a park! Like, where people come and can look at the creatures for an entrance fee? Yeah, sure why not. Also like your naming idea, perhaps something a little catchier?

Imagine a new generation of kids that likes dinosaurs and can actually see them roaming. Can't wait to see the look on their faces when I tell them that I was into dinosaurs when they were still underground

One idea I had a while back is this: with all our modern technology in stem cell research, gene modification and cloning, shouldn't it be possible to recreate actual living clones from prehistoric dinosaur DNA? I mean, sure, these giant wild animals could potentially become dangerous, but how about we confine them to a remote island or so?!

I believe that you will only need one IT person and I would like the job!

One thing humans could was starting fires that would drive many animals into a designated killbox, among other ways of "cheating". Humans were uniquely capable (at this size scale, at least) to both hunt species in excess to their need and cause outsized damage to their habitat in the process.
