AI Thread Summary
The discussion centers on the theoretical possibility of de-extinction for dinosaurs, highlighting significant challenges due to the age of their DNA, which is over 65 million years old. While some research has been conducted, such as DNA studies on more recent extinct species like the woolly mammoth, the recovery of dinosaur DNA remains elusive. Fragmented DNA has been detected in dinosaur bones, but it is too degraded for recovery or identification. The conversation suggests that while de-extinction is not entirely ruled out, current scientific capabilities are far from achieving it. The most feasible approach might involve using avian DNA to hypothesize dinosaur structures, but this would still be speculative. Overall, the consensus is that while theoretically possible, practical de-extinction of dinosaurs is not currently achievable.

You mean like Jurassic Park?

Animals can be introduced to an environment (like wolves) but you need those live animals to begin with.

There was some DNA studies on the wooly mammoth but that species was far more recent than 65mya

The closest would be the detection of some DNA fragments in dinosaur bones, but it was in so bad shape that it could not be recovered, nor identified.

Closest to successful recovery of DNA would be this I think. But compared to the age of dinosaurs 700000 years is still very 'young'.

To say that it is not possible at all goes too far, but it is safe to say that we are so far to success that we don't even know how far that is.

Sadly, DNA from that far back (64 MYA+) does not retain its structure. More recent extinctions (Neanderthals, Giant Moa, Tasmanian Wolves, Dodo,...) are (or soon will be) reversible because we have DNA fragments that can be stitched back together from museum specimens etc.

With dinosaurs the best bet would be to use bird DNA to reconstruct probable structures - but they would still only be guesses.
