TYRANNOSAURUS REX PRESERVED BLOOD CELLS
_______________
Mary Schweitzer was working as a researcher at the Museum of the Rockies in Bozeman, Montana. While cleaning some T. rex bones Schweitzer and an assistant found something remarkable. What they found inside the bone matrix was what appeared to be unfossilized blood cells within blood vessels and other tissues [1]. The tissue was in remarkable preservation for being estimated to be over 65 million years old. This means that the blood cells and vessels would have to remain relatively uncorrupted for that vast amount of time in bones that were exposed to the elements.
The research done by Michael Buckley of Manchester Interdisciplinary Biocentre has estimated the limit for the survival of collagen in optimal conditions is 700,000 years [2]. Collagen is the protein that makes up around 25%-35% of body tissues and when decayed the tissue would not be recognizable. Schweitzer’s T. rex blood cells and vessels would have decayed long ago if the age of the bones were indeed over 65 million years old.
This represents a major problem between the assumed age of the dinosaurs and the survivability of the soft tissues that are contained within their unfossilized structure. This problem could possibly be written off as an outlier is this was the only case of soft tissues found within dinosaur bones but it is not, it is quite common in paleontology.
