Patriomanis americana is the only pangolin, living or extinct, known from the Western Hemisphere. Initially described over 40 years ago from a partial skeleton, since then several nearly complete skeletons have also been discovered in latest Eocene (Chadronian North American Land Mammal Age) deposits of central Wyoming and western Montana. Together these fossils include nearly every bone in the skeleton, making it not only the most completely preserved fossil pangolin taxon but also among the best preserved Eocene mammal taxa. This study contains a detailed, bone-by-bone description of the osteology of Patriomanis and comparisons with other well-known fossil pangolin skeletons.
The latest issue of Atoll Research Bulletin asks, "How many atolls are there in the world?" The answer: 439. And all of them are listed and mapped in this indispensible new resource for atoll research.
Initially published in 1968 by the Smithsonian’s then Office of Ecology, this checklist was based on botanist Daniel Higman’s exploration of plant species found on three tracts of Smithsonian-owned land near the Chesapeake Bay in Maryland that represented a broad spectrum of ecological systems. As part of the 50th-anniversary celebration of the Smithsonian Environmental Research Center (SERC), this first-known SERC publication has been updated and republished.
