Can this be done ? please explain.

Doubt there's enough DNA fragments from any one species of dinosaur remaining to rebuild one. But (theoretically) some extinct creatures could be resurrected one day using tissue from museum specimens
DNA tends to break down over time, but if you had enough copies of decent bits of DNA in the lab, you could (theoretically) piece together the original DNA sequence, perhaps by reference to a similar modern species. You could then recreate the entire DNA molecule, insert it into the fertilised egg of a similar modern species and implant it into a surrogate mother.
The technical challenge would be immense though, and is way beyond current capabilities. Sequencing itself would be a mammoth (?) task. We are able to manipulate DNA molecules, cutting and splicing sequences, but building an entire molecule from scratch would be an almost inconceivably (!) difficult job. Then getting the embryo to survive in a foreign womb is not straightforward either.
Another possibility may come to light once we understand more about how DNA works. In all creatures, including us, most of the genome is redundant "junk" DNA, and it's thought that a lot of information about the ancestry of species might be found there. So we might have (switched off/ mutated) copies of genes in our genome that formed part of the active genome of our ancestral ape-like species. By looking at the common genetic information shared by similar modern species, we might one day be able to deduce what some of the DNA sequences of their common ancestors might have been, and use this as a starting point. Maybe the DNA of dinosaurs still exists, spread about among their descendants - reptiles and birds?
Technology moves on a lot year to year, so maybe one day. But I think we'd be talking about creatures that lived up to a few thousand years ago, rather than millions. Sorry, you'll have to make do with the movies for now!

There was a documentary about this on TV some time ago. Scientists found a dinosaur egg that was preserved unusually well. They tried to revive it, clone it or reproduce it, using genetic splicing and other methods. The experiments did not work, but the whole concept was nonetheless very interesting.

No. the proper blueprint for their shape, that's the DNA, is lost completely. DNA can not final for greater suitable than hundred thousand years. Dinosaurs disappeared sixty 5 million years in the past. Fossil DNAs meant to be that previous are surely plenty greater moderen bacterial DNAs contaminating the unique species in the process the final hundred thousand years. Cloning those DNAs is probable to offer far deadlier extinct micro organism than dinosaurs

Anything is possible given time and money. But before we start resurrecting terrible lizards, perhaps we should consider protective measures.
Even if we can't get their genome completely mapped, eventually genetic engineers will figure out how to fill in the blanks when they get a better understanding of how to translate the dna code.
If someone does figure it out and goes ahead with it....
I certainly hope they can "supe" up us regular guy so we can put up a decent fight with the escapees.

watch jurassic park
it says that mosquitoes in amber may carry dinosaur DNA
but the question is that if the DNA is even usable
it is possible but it is either very complicated or it will take too long

Not that I can answer the question, but - why would you want to? It's like the old fable about the wise men who brought a dead lion back to life, and were consequently eaten by it... no much use for them, is there.

In theory it may be possible, but why? Todays environment would not support these animals, they are extinct, thier world is long gone, and they are scary, poor Jeff Goldblume, he was nearly eaten by one just ask him.

Maybe not, but in the future it may be possible to re-create them, or something very similar. One day we may be able to build any creature from scratch.

Why, do you miss him?
Personally I never cared for his singing.
