PSW: The Role of Paleoecology in Everglades Restoration

Please post the following meeting announcement:

The Paleontological Society of Washington

Wednesday, November 18, 7:00 pm, in the Cooper room (E-207A), National Museum of Natural History, Constitutional Ave. entrance

The Role of Paleoecology in Everglades Restoration

Lynn Wingard

Research Geologist /Project Chief, Eastern Geology and Paleoclimate Science Center, United States Geological Survey, Reston, VA

Restoration of the Florida Everglades is projected to take 30-50 years and the cost is currently estimated to be almost eight billion dollars. Success is contingent on restoring more natural hydrologic flow through the ecosystem and on understanding how the ecosystem will respond to projected climate and sea level changes over the next century. This talk will illustrate how paleoecologic data is guiding restoration efforts. Applied paleoecology is a reality!

Non-Smithsonian visitors will be escorted to the Cooper Room at 6:45 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitutional Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.

PSW: Carl Simpson on bryozoan polymorphs

Wednesday, October 21, 7:00 pm, in the Cooper room (E-207A), National Museum of Natural History, Constitutional Ave. entrance

Determinants of bryozoan polymorphism

Carl Simpson

Department of Paleobiology, NMNH, Washington D.C. 20059

The members of a bryozoan colony can have dramatic morphological differences. When this occurs the modified members are termed polymorphs. The evolution of polymorphism is an old problem that has resisted understanding since Darwin. I test and reject a hypothesis of environmental control and propose another based on the construction of life-history strategies coupled with the origin of novel polymorph types.

Non-Smithsonian visitors will be escorted to the Cooper Room at 6:45 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting.

PSW: The [chemical] origin of life

The [chemical] origin of life

Henderson Cleaves

Geophysical Laboratory, Carnegie Institution of Washington, Washington D.C. 20059

With the discovery of hundreds of extra-solar planets, scientists have been able to much more accurately fill in many previously unknown numbers of the Drake equation, which estimates the number of communicative civilizations which may exist in the Milky Way. Presently, the “bottleneck” unknown quantity is the number of planets on which life actually does arise, which is a reflection of how common conditions for the origin of life occur, and how easily the transition from non-living to living matter can take place. A brief history of the study of the origin of life and some current chemical perspectives on the problem will be presented.

Non-Smithsonian visitors will be escorted to the Cooper Room at 6:45 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitutional Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.

PSW: The ‘Chicken from Hell’

The Paleontological Society of Washington

Wednesday, January 21, 7:00 pm, in the Cooper room (E-207A), National Museum of Natural History, Constitutional Ave. entrance

The ‘Chicken from Hell’ – an unusual new theropod dinosaur from the Upper Cretaceous of North America

Dr. Hans-Dieter Sues, Curator of Vertebrate Paleontology, NMNH

Oviraptorosauria is a clade of maniraptoran theropod dinosaurs with peculiar craniomandibular specializations. Most discoveries of oviraptorosaurs have been made in Asia, principally Mongolia and China, and as a result, the balance of our knowledge of the group is derived from fossils found on that continent. Anzu wyelei, a new, large-bodied (total length ~3.5 m) oviraptorosaurian taxon based primarily on three well-preserved partial skeletons from the late Maastrichtian of North and South Dakota, will be discussed. The new taxon offers the first comprehensive picture of the skeletal structure of Caenagnathidae and sheds light on long-standing controversies regarding the taxonomy and interrelationships of North American oviraptorosaurs. Furthermore, its analysis confirms caenagnathid monophyly and provides additional insight into the paleobiology of this enigmatic clade.

(Non-Smithsonian visitors will be escorted to the Cooper Room at 6:30 and 6:55 p.m.) Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) shortly after 5:00 prior to the meeting. Members may meet inside the Constitutional Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.
