Preservation
Dinosaur fossils with Dakota's degree of preservation are extremely rare because many different factors must come together to allow it to occur. The carcass first must escape scavengers as well as degradation by the elements. The soft tissue must then be mineralized before it decomposes. Finally, as with all fossils, the mineralized body must escape destruction by geological forces over millions of years.
News reports have referred to Dakota as "mummified"; however, it is actually a fossil of a mummified dinosaur, where the animal's dried tissues have been transformed to rock through fossilization.

Famous quotes containing the word preservation:
“Men are not therefore put to death, or punished for that their theft proceedeth from election; but because it was noxious and contrary to mens preservation, and the punishment conducing to the preservation of the rest, inasmuch as to punish those that do voluntary hurt, and none else, frameth and maketh mens wills such as men would have them.”
—Thomas Hobbes (15791688)
“If there is ANY THING which it is the duty of the WHOLE PEOPLE to never entrust to any hands but their own, that thing is the preservation and perpetuity, of their own liberties, and institutions.”
—Abraham Lincoln (18091865)
“The preservation of life seems to be rather a slogan than a genuine goal of the anti-abortion forces; what they want is control. Control over behavior: power over women. Women in the anti-choice movement want to share in male power over women, and do so by denying their own womanhood, their own rights and responsibilities.”
—Ursula K. Le Guin (b. 1929)
