Conclusion

This paper demonstrates what can be achieved with the current level of computer simulation technology. The simulations do demonstrate a wide range of possible locomotor modes and shows (a) that 10 independent repeats is probably insufficient for a quadrupedal gait analysis and (b) that there are major gaps in our understanding of gait choice that are highlighted by this process. Whilst bipedality is currently the most likely option, a high-speed quadrupedal hadrosaur should not be ruled out as a serious locomotor possibility for this group of dinosaurs.
