Dinosaur Blood and Collagen — For the Birds!
A study on preserved collagen and red blood cells in dinosaur bones, as well as the fossilization process, was marred by the evolutionary mindset of the researchers. Taking the approach that dinosaurs evolved into birds, they did some selective research on commonalities in some areas, and conveniently ignored how these things appear in other critters besides birds. Their unwarranted extrapolations did not give them any clues to origins.
The problem remains that blood and collagen should not last for millions of years, and is remarkable for having lasted the thousands of years after the Genesis Flood. Indeed, the biblical Flood models fit the actual observed facts far better than any evolutionary interpretations.
Red blood cells and connective tissue may be preserved in dinosaur fossils more commonly than previously thought. This suggestion came from scientists on June 9, 2015 in Nature Communications as they unveiled the Cretaceous cells and collagen they recently found. The study’s authors compared the apparent red blood cells in a dinosaur claw to those of an emu. They attributed their similarity to an evolutionary connection between birds and dinosaurs.To read the rest, click on "Preserved Cretaceous Collagen and Dinosaur Blood: Common Clues to a Catastrophic Past?"
Well-preserved fossils occasionally contain soft tissues like blood and collagen, a fact repeatedly documented since Mary Schweitzer’s controversial 2005 discovery of red blood cells and pliable blood vessels in a T. rex femur fossil presumed to be millions of years old. The fossils harboring the latest serendipitous discoveries, however, are a junk assortment found on the surface at Canada’s Dinosaur Park Formation and left in storage at London’s Natural History Museum. The authors of “Fibres and cellular structures preserved in 75-million-year-old dinosaur specimens” say they appear poorly preserved compared to others in which soft tissue has been found, and there was no external evidence suggesting soft tissue might be present. In fact, they obtained leave to invasively study these fossils, hoping to learn about the fossilization process, because they were not particularly pristine. (As coauthor Susannah Maidment explained, “It’s really difficult to get curators to allow you to snap bits off their fossils.”1) And chipping into six of eight miscellaneous dinosaur bones, they found either collagen fibers (in one), other fibers (in three), or cell-like structures (in two).
