Tracks like these preserve a fleeting moment in time for millions of years – and we think that’s pretty cool 😎 But here’s the thing about fossil trackways, unless the track-maker died and just so happened to be fossilized alongside the tracks, it’s nearly impossible to say with confidence exactly which ancient critter made these footprints! So, in the case of these gorgeous tracks from Glen Canyon National Recreation Area (@glencanyonnps), the most accurate description would be to say that these are “Theropod tracks with Ornithopod-like morphology” 🤓 .....which is to say that one of the bipedal, meat-eating guys stepped in some squishy mud and made tracks that looked more like the footprints of the plant-eating guys. Even though we don’t know exactly who made them, tracks and other trace fossils allow us to understand more about the behavior and life of these animals who existed millions of years ago which, again, we think is pretty cool 😎 Learn more and explore the model yourself at https://bit.ly/JWPowell-track-block-glen-canyon! #FossilFriday #Fossils #NPS #Photogrammetry #3D #3Dmodel #Geology #Paleontology #PublicLands #GlenCanyon #NationalRecreationArea #Utah #Tracks #Desert #Theropod #TraceFossil #Ichnology #ProtectPublicLands #EarthScience #Science #Education #Reels
