“Dinosaur Mummy” Found; Has Intact Skin, MuscleSee also here.John Roach
for National Geographic News
December 3, 2007Scientists today announced the discovery of an extraordinarily preserved “dinosaur mummy” with much of its muscles and bones still encased in an uncollapsed envelope of skin.
Preliminary studies of the 67-million-year-old hadrosaur, named Dakota, are already altering theories of what the ancient creatures’ skin looked like and how quickly they moved, project researchers say. (See pictures of the mummy dino and its preserved skin.) …
The preliminary calculations suggest Dakota could run 28 miles (45 kilometers) an hour. Tyrannosaurus rex tops out at about 20 miles (32 kilometers) an hour, according to the model. (Related: T. Rex Quicker Than Fastest Humans, Study Says [August 23, 2007])
For Manning, the finding makes perfect sense. Hadrosaurs are believed to have been T. rex prey, so evolution would have favored a faster running speed.
Picture slideshow of this hadrosaur is here.

Dino “mummy” has skin turned to stone:
A startlingly well-preserved dinosaur may have had
stripes and the ability to outrun T. rex, according
to researchers.

Hi eva, palaeontologists expect many hundreds of “new” dinosaur species will yet be found in the future; maybe some of those also with muscles and other features preserved.
