New frontiers in crinoid paleobiology: building and exploring the crinoid tree of life

Crinoids are a diverse group of marine invertebrates with a rich fossil record that spans nearly 500 million years and includes over 8,000 named species. Recently, significant efforts have been made to resolve evolutionary relationships among crinoids, resulting in major advances in understanding the crinoid tree of life. As a result, crinoids are rapidly becoming a model group for addressing paleontological questions within an evolutionary context. This has opened many new avenues for research in crinoid paleobiology, including studies of extinction, evolutionary radiation, paleoecology, and morphologic change.
Non-Smithsonian visitors will be escorted from the Constitution Ave. entrance of the NMNH to the Q?rius auditorium at 6:50 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 Constitution Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.
