T-Rex: 12. MAGNESIUM
T-Rex: A common metal - there's enough on Earth to make a solid ball of magnesium the size of Mars!
Utahraptor: You'd need a giant mould to make it in.
T-Rex: You could use all the iron and silicon as a mould.
Utahraptor: You'd end up with a ball of iron, silicon, and magnesium the size of Earth.

Magnesium also burns really well. So well, that it can't be extinguished by either carbon dioxide or water. The reaction simply destroys the molecules, stripping the oxygen atoms off the carbon or hydrogen so the magnesium can keep on burning.
They used to make car wheel rims out of this stuff - the original so-called mag wheels. With occasionally predictable results.
