David R. Schwimmer proposed in 2002 that several hadrosaurid tail vertebrae found near Big Bend National Park show evidence of Deinosuchus tooth marks, strengthening the hypothesis that Deinosuchus fed on dinosaurs in at least some instances.
David R. Schwimmer foreslog i 2002, at fordi adskillige hadrosauride haleryghvirvler, fundet i nærheden af Big Bend National Park, viste tandmarkeringer fra Deinosuchus , kunne det styrke hypotesen om, at Deinosuchus i det mindste spiste dinosaurer i nogle tilfælde.
