Pi Day

Today, March 14, is Pi Day. Brett suggested that I mark the day by writing a non-repeating, non-ending blog post, but I though that might be a little beyond my writing stamina limits (not to mention your reading stamina). Therefore, I’ve decided to post pictures of Nature’s tributes to the circle, as expressed in various fossils. Enjoy!

Probable barnacle scar on a whale bone:

Tooth sockets from Squalodon whitmorei:

    The [Diatom Coscinodiscus Marginatus] picture also reminded me of the Fibonacci Sequence. Similarities include pine cones and the center of a sunflower. -Gary Alcina
