Soft Tissue Found Inside A Dinosaur Bone!

Did scientists really discover soft tissue inside a dinosaur bone? Find out here, and learn what this might mean!

Overview

In 2003, an exceptionally well preserved T. rex leg bone was unearthed in the cretaceous rocks of Montana. Upon close examination, Dr. Mary Schweitzer found the bone to contain soft tissue inside – tiny blood vessels and proteins! Some claim that this is evidence of a young Earth, a recent extinction of the dinosaurs. Could this be, or is there another explanation?
