Dust Grains Older Than Our Sun Found In Asteroid Ryugu Samples

Opalized ammonite: A beautiful example from Alberta, Canada of the intersection of biological evolution and mineral evolution — the interplay between minerals and life. A hundred million years ago, the ammonite deposited its own hard carbonate shell — a "biomineral." In this rare case, that original carbonate shell was later replaced by the fiery mineral opal.
