Scientists have found soft tissue in the thigh bone of a tyrannosaurus rex. The discovery was made when they had to break the bone in order to fit it in the helicopter.
In the laboratory they found what they believe could be blood vessels, bone cells and blood cells. In some cases the material was so soft it could be squeezed out. The researchers hope that some museums may break some fossils to look for more tissue
The find may help to answer many questions about dinosaur physiology but casts serious doubt on the current models of how fossilisation occurs. Scientists say it is too early to know if we will see dinosaur DNA but are hopeful.
