Many Dino Fossils Could Have Soft Tissue Inside: "Soft-tissue dinosaur remains, first reported last year in a discovery that shocked the paleontological community, may not be all that rare, experts say.
A 2005 paper in the journal Science described what appeared to be flexible blood vessels, cells, and collagen-like bone matrix from fossils of a 70-million-year-old Tyrannosaurus rex."
Mary Schweitzer, the North Carolina State University paleontologist who announced the finding, said her team has now repeated that feat with more than a dozen other dinosaur specimens.
To make sense of the surprising discovery, scientists are beginning to rethink a long-standing model of how the fossilization process works. [News]
