    It’s pretty obvious that they can.

    Do ye not remember Jurassic Park 1 where the fat IT dropped the shaving can full of embryos.

    That will be found.

    Let's say it were possible, then you run into a few problems, not least of which is the air we breathe today. Back in the age of dinosaurs there was a significantly higher percentage of oxygen in the atmosphere. So for the bigger ones, well anything much beyond dog sized you're running into problems of not enough O2 for them to breathe. Then there are diseases around now that weren't around then. Temperatures could be another problem as again back in their day the earth was hotter than it is today.

    Rejoice in the awareness of feeling stupid, for that’s how you end up learning new things. If you’re not aware you’re stupid, you probably are.

    It's pity they don't try to bring back some species that died out more recently due to human activity like the thylacine or dodo.

    We'll sort that out.
    Global warming,
    more CO2 more plants,
    more plants more oxygen....

    If we start selectively breeding very large birds like ostriches and emus with particular interest in excessively large or aggressive specimens we might be on our way towards it.

    I have no idea why we would want to do that though.

    Lads, there's been a series of film about why this would be a very bad idea.

    Some don't.

    It's not like we're going to put dinosaurs in the zoo or seaworld or some sh1t.

    There could be some in the zoo, like we do with elephants. And the super rich could have them as pets. They could afford to pay someone to take them for walks.

    Do you think there's a possibility that a species resembling the dinosaurs might exist on another planet?

    If they can grow an ear on a rats back I'm sure it is possible.

    A human ear ?

    if they find some insect that was sucking their blood then somehow got preserved in amber or something, piece of cake, they could bring them all back and even make up new ones. maybe set up some sort of reserve on an island where people could visit...

    I'm stealing you're movie idea

    I'm going to go out on a limb and suggest that if someone does bring back a t-rex the percentage of oxygen in the atmosphere is going to be pretty far down the list of problems that people raise.

    I've seen this movie.

    Well, it was a human ear shape. Roughly.

    They grew cartilage on a mouse’s back around an ear-shaped framework, and used a mould on the outside to make it look like an ear. It looks freaky, but is not an actual human ear, it wouldn’t have grown that shape if it wasn’t confined to the mould, and they didn’t even use human cells. The cartilage cells came from a cow.

    It’s been done on rats since, but with the same technique.
