Living With Dinosaurs
Feb 7th
In 2005, a team of scientists led by paleontologist Mary Schweitzer discovered a femur bone from a Tyrannosaurus Rex.
Nothing particularly special about that, until they also discovered that the bone contained intact blood vessels, red blood cells, and other proteins. An amazing find: Tyrannosaurus Rex soft tissue!
But this posed a big problem and challenge to the conventional theories about dinosaurs. Why? Because we know that proteins like the type found in this dinosaur bone degrade quite quickly, and would not be expected to last longer than a few thousands years, even under ideal conditions. Just exactly what had we stumbled upon here?
Then again in 2009, the same team discovered the fossil of a duck-billed dinosaur that also included soft tissue structures such as collagen, elastin, and hemoglobin. Again, no evidence suggests that these kind of tissues can last more than a few thousand years, let alone the 60 million years that have supposed to have lapsed since dinosaurs died out.
The truth is that in fact there is a growing number of scientists that subscribe to “young earth” theory, challenging the long held beliefs that the earth is millions of years old. These scientists claim to have plenty of proof that the earth is in fact only a few thousand years old, and that men and dinosaurs did actually co-exist together at one point in time. It’s fascinating.
