Elemental map of the isotope strontium (Sr) from dinosaur eggshell

Caption

Elemental map of the isotope strontium (Sr) from dinosaur eggshell collected from Teel Ulaan Chaltsai, Eastern Gobi Basin.  Elemental maps were used by the researchers to evaluate if the uptake of strontium (Sr) was uniformly distributed across the eggshell. A uniform distribution indicates that uptake of this and other isotopes occurred after burial but prior to fossilization.
