       With a morphology like we see in lizards today,‭ ‬Thadeosaurus had a very long tail making up over half of its total body length.‭ ‬The legs were long and had long toes terminating in claws.‭ ‬It is likely that as Thadeosaurus ran,‭ ‬the toes would always be in contact with the ground.
       Thadeosaurus had a well developed breastbone suggesting attachments for powerful muscles in the upper body.‭ ‬As well as running,‭ ‬it may have been able to combine this strength with the claws on its long toes for climbing.‭ ‬Bringing all these adaptations together results in Thadeosaurus being a fast and agile predator easily capable of running its prey down.
