Re: T-Rex soft tissue?

The ecosystem question is an interesting one.
I would assume that it would be very similar to current introduced species. 
Something like 90%
wouldn't be able to survive, another few percent would be able to hang on and 
not spread and maybe
one or two percent would become invasive. It is predicted that invasive species 
with more than 90%
leathality rates will wipe out at least 40% of deciduous tree species in North 
America if allowed to

Once you loose trees (even half of a species) the forest makeup changes and you 
have a disturbed
environment which is much more attractive to other invaders. Human disruption 
through logging and
other activities adds a lot to the problem (you can think of highways bending 
space like worm-holes
in this context).

It raises a lot of interestsing questions about ecosystem replacement and

    I know, for example, that there were various projects that were going on
(I don't know if they still are) to revive various extinct species, but they
pose an interesting idea. I'm a high-school student and I did various
projects involving this. One of which involved brief research in reviving
extinct mammals- the Tasmanian Tiger, through a preserved juvenile. Another
case was done by Japanese scientists who intended to clone wooly mammoths
from frozen remains and semen.
(http://news.bbc.co.uk/1/hi/world/asia-pacific/3075381.stm). They were
unsure whether to carry on with the cloning or not due to various issues
(diseases the mammoths could potentially carry, etc.). I know that over time
DNA fragments, and becomes useless. Would it be possible to clone a dinosaur
and have it thrive with the current plants and environments if a scientist
found a good sample in the bones, just like how scientists unearthed the
Tyrannosaurus tissue? Just trying to quell my curiosity...
