From its founding in 1895 right up to the present day, Carnegie Museum of Natural History has played a vital role in the development of vertebrate paleontology in North America. This meeting represents a homecoming for the Society, and it provides us with the opportunity to showcase the museum’s recently renovated Mesozoic gallery, Dinosaurs in Their Time. Pittsburgh is conveniently located in southwestern Pennsylvania, affording easy travel connections by air, rail, and major highways. The city is home to numerous scientific and cultural institutions, as well as several major universities. Autumn visitors to the region can enjoy the fall foliage in the Laurel Highlands, which is home to the museum’s Powdermill Nature Reserve and Frank Lloyd Wright’s architectural masterpiece, Fallingwater. We look forward to hosting the meeting and seeing you in Pittsburgh! 2010 SVP Host Committee Presentation Policies SVP Abstracts are reviewed by the Program Committee and occasionally by outside reviewers.
