I don't think anyone is considering this as really bringing them back and releasing them into an ecosystem, just Jurassic Park type novelty.

I think containment for such organisms could be more challenging beyond the Jurrasic Park movie plot. For example would we also have to account for side effects such as horizontal gene transfer[0]?

If you bring them back, it's only a matter of time before they are in the ecosystem. Maybe we contain it for a decade, a century at most but it's going to happen. It's basically the plot of the entire movie series.

I think that's unrealistic - they either eat all their food (if there is even a climate they can survive in) or they get caught. Though this won't apply to small species as much. But the small dynos won't necessarily ruin the ecosystem as they won't be the apex predator. Not like a T-Rex is going to run around without being found, unless the host country collapses and no one cares. But it will just go extinct again, after causing some damage.

Ask an aussie how much damage something as innocuous as a rabbit or a frog can do when in an ecosystem they weren't meant for.

Matter of time. Human life timescale too, not evolutionary timescales

Sounds real fun, I totally want that to happen /s
