Biological Cells Found In Dinosaur Bone Confirmed To Be 67-Million-Year-Old Collagen, Possibly Contain DNA

October 25, 2012 in Animals & Insects, Fossils

In 2005, what appeared to be preserved soft tissue was found inside of a 67-million-year-old Tyrannosaurus Rex bone. This soft material was confirmed by later research to be collagen. And now new research has provided further strong evidence that these are in fact dinosaur proteins, and not the result of microbial contamination.


The primary evidence is the soft tissue’s reactivity to antibodies that only target specific proteins found in the bone cells of vertebrates. This rules out microbial contamination. And strongly suggests that there are actual T-Rex cells preserved in the soft tissue, and possibly DNA.
