As much as I love trilobites, here is a photograph I took of pretty Mississippian-age crinoids on display at the Smithsonian Museum.
Ok, ok, Matt has a trilobite head for you who insist. Happy Fossil Day! Hug your favorite dead-and-preserved-in-the-rock-record critter today! Don’t forget to donate to science classrooms in honor of Earth Science week, either!
