Hey, we're going to be doing something really cool!The next 3 episodes will be brought to youin part by The Field MuseumThe Museum of Comparative Zoologyat Harvard University, and theNational Science Foundation.:introduction jingle begins:Do you ever wonder how paleontologistsfigure out how prehistoric animals move?Based off of only skeletal evidenceas well as trace fossils, like fossil footprints,we can start to get an understanding.For instance, take Dimetrodon.An early proto-mammal, and not a dinosaur.A paleontologist was able to take measurementsof the shoulders, and hipbones of a Dimetrodon fossiland then compare the range of motionof those joints to fossil trackways.The results give us a good ballpark estimatefor how this creature, which lived nearly300 h...
