The T. Rex paper is right. I'm surprised you haven't heard of it, Skinwalker. Although, it's not really what you might think. What they did was dissolve the bone and some of the veins inside the bone were soft. A short thread on it from back when: http://www.sciforums.com/showthread.php?t=45937 And the science paper: Soft-Tissue Vessels and Cellular Preservation in Tyrannosaurus rex Mary H. Schweitzer, Jennifer L. Wittmeyer, John R. Horner, and Jan K. Toporski Science 25 March 2005; 307: 1952-1955 [DOI: 10.1126/science.1108397] (in Reports) http://www.sciencemag.org/cgi/conte...ex&searchid=1&FIRSTINDEX=0&resourcetype=HWCIT They probably 'disappeared from the news' because laymen were disappointed that the soft tissue wasn't what they thought it was nor did it mean what they thought it meant. As a matter of fact, the paper is more about the similarity between T. Rex bones and bird bones, if I recall correctly. The soft tissue thing was more sensationalism than anything else. Of no great import.
