We're getting to know Tyrannosaurus rex even better... Scientists discovered blood vessels, containing blood and bone-building cells , inside the fossilized leg of a 68-million-year-old dinosaur recently. They hope that there will be genes recovered, which will aid scientists in determining dinosaur gender, whether they were cold- or hot-blooded, and how tyrannosaurs were related to modern birds.




The dinosaur's eloquent lesson is that if some bigness is good, an overabundance of bigness is not necessarily better.
