Dinosaur Soft Tissue Find Proves False

In 2005 researchers apparently found soft, pliable tissues had been recovered from dissolved dinosaur bones. But new finding suggests that the supposed dinosaur tissue is in reality biofilm.

The original research claimed the discovery of blood vessels and what appeared to be entire cells inside fossil bone of a Tyrannosaurus rex. The scientists had dissolved the bone in acid, leaving behind the blood vessel- and cell-like structures.

As the article in Science Daily puts it:
  • But in a paper published July 30 in PloS ONE, a journal of the open-access Public Library of Science, Kaye and his co-authors contend that what was really inside the T. rex bone was slimy biofilm created by bacteria that coated the voids once occupied by blood vessels and cells.
