Re: Oldest Dinosaur Discovery



    I have the good news that the photo used by MSNBC is not the new oldest
dinosaur found, its from another one, possibly _Santanaraptor placidus_,
shown last year to the world.
    If you want to take a look at the remains of this new oldest dino, the
url is:

tm&subTab=00000
    The only matter is that the whole text is in portuguese, but I'll send
in a few minutes translated...
