Scientists have recovered 70-million-year-old soft tissue inside a Tyrannosaurus Rex bone they found in a sandstone formation in the US.
The find included what appeared to be blood vessels, and possibly even cells.
The material is currently being studied, and if scientists can isolate proteins from the material they may be able to learn new details of how dinosaurs lived, lead researcher Mary Higby Schweitzer of North Carolina State University said
