Did I miss any news? "The spheres may have formed when molten rock was sprayed into the air by a volcano or a meteor impact." - Wikipedia (your link)
My original: "My first thought would be sphericles created by the liquifying of the rock when the meteor struck. They'd form into sphericles, then harden before landing."
My question concerned their uniformity of size!
