For the last 15 years, Dr Mary Schweitzer has been rocking the evolutionary/uniformitarian world with discoveries of soft tissue in dinosaur bones.¹ These discoveries have included blood cells, blood vessels, and proteins like collagen. But under measured rates of decomposition, they could not have lasted for the presumed 65 million years (Ma) since dino extinction, even if they had been kept at freezing point (never mind the much warmer climate proposed for the dinosaurs).² As she said in a popular TV show:

When you think about it, the laws of chemistry and biology and everything else that we know say that it should be gone, it should be degraded completely.³..........................

Schweitzer’s more recent research makes long ages even harder to believe. Here, she analyzed bone from two dinosaurs, the famous Tyrannosaurus rex (MOR 1125¹⁰) and a large duck-billed dinosaur called Brachylophosaurus canadensis (MOR 2598).¹¹ Bone is an amazing structure with the ability to re-work in response to stress,¹² and uses the finely designed protein osteocalcin,¹³ which has been found in the best known duck-billed dinosaur, Iguanadon, ‘dated’ to 120 Ma.¹⁴ The most plentiful cells in bones are osteocytes. These have a distinctive branching structure that connects to other osteocytes, and have a “vital role” in “immediate responses to changing stresses.”¹⁰
