The Mystery of the Holes in SUE’s Jaw

Since their unveiling in 2000, SUE the T. rex has been studied by scientists around the world, yet mysteries remain about the Field’s most famous fossil. What caused holes to form on SUE’s lower jaw and what can this tell us about how they lived and died? Join paleontologist Jingmai O’Connor, Curator of Fossil Reptiles, as she shares some of the mysteries about SUE the T. rex scientists are continuing to solve, and hear how she and her team were able to prove one of the most popular theories about the cause of holes in their lower jaw–that they suffered an infection from a protozoan parasite–couldn’t be true.

This event is part of Summer of SUE - celebrating 25 years of SUE the T. rex at the Field Museum. Check out the rest of the SUE-lebrations we have planned for this summer!
