"Sue," the largest and most complete Tyrannosaurus rex skeleton yet uncovered, will be the subject of a 10 a.m. Saturday, Sept. 28 presentation, "The Dead Speak: Lessons from Tyrannosaur," by Christopher Brochu, assistant professor of geoscience in the University of Iowa College of Liberal Arts and Sciences (CLAS), in Room 40, Schaeffer Hall.

The free, public talk is part of the CLAS Saturday Scholars series. He will also be a guest on "Iowa Talks," WSUI, AM 910, at 10 a.m. Thursday, Sept. 26.

"My talk will be about Sue, the 'T. rex' at the Field Museum and the work I did on Sue," Brochu says. "I'll talk about what Tyrannosaurs are, what makes them such unusual animals, and what makes Sue such an unusual Tyrannosaur.

"The public is fascinated with dinosaurs -- that's why I teach a class called "The Age of Dinosaurs" for undergraduate non-majors here at Iowa. And, Tyrannosaurus rex is an ambassador for science -- it gives us a chance to do science that will be of interest to the public."

Brochu has taught at the UI since 2001, after having earned his bachelor's degree in geology from the University of Iowa in 1989 and his master's and doctorate from the University of Texas at Austin in 1992 and 1997, respectively. From 1998 through 2000, Brochu was a postdoctoral research scientist at the Field Museum in Chicago, where his primary duty was the completion of a monographic description of "Sue." At Iowa, his research focuses on the evolutionary history of fossil and living archosaurs, especially crocodiles and theropod dinosaurs, and the comparison of molecular and fossil-based methods of estimating divergence times between evolutionary lineages. He also teaches courses in vertebrate paleontology.

Future lectures in the Saturday Scholars series include:

-- Oct. 12 "Jewish Women in India: Rethinking the Middle East," Jael Silliman, associate

professor of women's studies

-- Oct. 26 "Just Beneath My Skin: Autobiography and Self-Discovery," Patricia Foster,

associate professor of English

-- Nov. 9 "The Neanderthal Mystery: Who Were They and Why Did They Disappear?" Robert Franciscus, assistant professor of anthropology

All presentations will begin at 10 a.m. in room 40 Schaeffer Hall, the southeast building on the UI Pentacrest. Each session will last about an hour, including a 20-30 minute presentation followed by a question-and-answer session. Refreshments will be served. Additional information is available at:
