Just discovered this site, and it looks to be quite good. Start with their post on paleontologist Hildegarde Howard, because she identified fossil passenger pigeons out west:
Artifacts from the early Spanish site in St. Augustine, Florida (associated with Pedro Menendez de Aviles, not Ponce de Leon) are being donated to the Florida Museum of Natural History at the University of Florida. U. Florida archaeologists have been excavating the site, and storing the artifacts, for many years, so it appears this will make the curatorial arrangement permanent, and perhaps provide a tax break for the owners of the site.
