It's Friday Fossil Day, and although all my fossils are boxed up or at my other home - I'm here at my little house in the "Nevada outback" - you can see fossils on several other geoblogoshperic sites:
Nova Geoblog has some neat Silurian fossils, including trilobites, my favorite (next to dinosaurs).
Geotripper has a Mesozoic fossil from the Sierra Nevada.
Clastic Detritus has a very nice, and possibly popular (see comments) crinoid fossil from New Mexico. Crinoids are some of my favorite friends. UPDATE: Mel has a photo of the same crinoid at Ripples in Sand.
Geology.com has a link to a new plesiosaur fossil from a mine in Canada.
And Dinochick often has some good dinosaur fossils and other paleontological information, including a recent post about the Gray Fossil Museum. UPDATE: Dinochick has some wonderful stromatolites for Fossil Friday - 1.1 billion years old!
UPDATE: The Lost Geologist has a mysterious fossil for his Weekend Fun series.
Search around, and you will probably find some more good fossil pictures and sites!
