T-Rex Bone Yeilds Soft Tissue Structures

Palaeontologists have extracted soft, flexible structures that appear to be blood vessels from the bone of a Tyrannosaurus rex that died 68 million years ago. They also have found small red microstructures that resemble red blood cells.

The discovery suggests biological information can be recovered from a wider range of fossil material than realised, which would greatly help the tracing of evolutionary relationships.

Reported by Jeff Hecht in New Scientist.
