In December 2007 Dr. Carr co-authored a scientific publication in the Journal of Vertebrate Paleontology regarding the occurrence of wrinkles in the teeth of meat-eating dinosaurs. It was thought that tooth wrinkles were only found in carcharodontosaurids (shark-toothed lizards, such as Acrocanthosaurus in the Museum's gallery), but a survey of theropod teeth shows they are present in many other meateaters, including Tyrannosaurus rex.
