These are fossil diatoms from the Puente formation in California. It can be tough to find undamaged diatoms from fossil material, there is one wreck and some chips out of some of these.

Diatoms
Nice stuff. Even with commercially processed Diatomaceous Earth, with a patient search you can find some intact specimens. When we vacationed in Greece last year, I brought home some seawater samples and found many diatoms I had seen in commercial Diatomaceous Earth.
Fun Fact - Years ago Diatomceous Earth was a prominent ingredient in toothpaste, until someone figured out how abrasive it was.

I had heard about the toothpaste thing, I bet your teeth really shined.. For awhile anyway.
One other interesting, almost unbelievable Diatom fact is that it is estimated that diatoms produce somewhere between 20 to 25% of the Earth's oxygen. Crazy to think these tiny things do so much.
Thanks for the interest.
