"The universe is full of magical things, patiently waiting for our wits to grow sharper." -- Eden Phillpotts.
GrrlScientist is an evolutionary biologist, ornithologist, aviculturist, birder and freelance science and nature writer. A native of the Pacific Northwest, she relocated from Seattle to NYC with her parrots after earning a BS in Microbiology (emphasis in Virology) and PhD in Zoology (Ornithology) from the University of Washington. In NYC, she was the Chapman Postdoctoral Fellow at the American Museum of Natural History for two years, pursuing part of her "dream" research project by reconstructing a molecular phylogeny of the parrots of the South Pacific islands. GrrlScientist has written a blog about science since 4 August 2004 (the early years are archived here) and was part of the original invited group of 14 "SciBlings" -- her only claim to fame. If you appreciate GrrlScientist's writing, please help her pay her living expenses by clicking on the Paypal button below and by voting for her to be the official blogger on a month long adventure in Antarctica. If you read an essay that you especially enjoyed, please nominate it for OpenLab2009.

Hi Science Girl, you've probably received tons of emails from other geologists, but your mystery object is an ammonite fossil, a nautiloid sea creature which lived between the Silurian/Devonian (ca. 400 million years ago) and became extinct with the dinosaurs at the end of the Cretaceous (65 Ma). Definitely one of the more spectacular fossils! Nice photos and content on your site by the way.
Cheers,
Jacques
Geologist

Having been in the NHM this morning, the 'missing' plaque identifies it as Asteroceras Stellare from the Early Jurassic

If you examine my comment, you'll see I hid the correct answer in a link.
A few other people guessed ammonite as well.
