India reached its record highest polio cases in 1992. During the 1990s, 60% of all polio deaths were occurring in India. The universal pulse polio vaccine drive was initiated in 1995 with 75 million children were vaccinated in two months. I was one of them. In 2014, India was declared polio free

#fossilfriday After 20 years, I finally found clam geodes in the Purisima Formation in Santa Cruz, CA! These are ~5 myo Clinocardium (cockle) shells that were incompletely filled in by sediment after death. Groundwater rich in dissolved calcium carbonate then precipitated calcite crystals.
The part and counterpart of a clam geode. The mouth of the clam is pointed down and there is a wedge of cemented sandstone at the bottom; the upper 2/3 of the clam is infilled with incredible amber colored dogtooth spar calcite, about 6-8 mm thick.The part and counterpart of a clam geode.
