No blog of mine could be complete without...dinosaur footprints! (*dramatic chord*)

These are pieces of, as labelled, the "Zerbst Trackway", which is a from the Lance Creek Formation, Upper Cretaceous (65 mya) . Trackway A was made by a Struthiomimid dinosaur ("ostrich mimic"), and Trackway D (up top) has Oviraptorid and avian (bird) tracks, as well as Tyrannosauroid tracks of some sort. Parts B and C had evidence of Edmontosaur-like prints (a herbivorous, hadrosaurian "duck-billed" dinosaur) and its accompanying "tail-drag" mark. Not to say that these animals were dragging their tails all the time, but the tip of a tail can easily scratch the ground, if the animal's crouching. The trackways are housed at the Black Hills Institute of Geological Research in Hill City.
