We have travelled to the Morrison formation which is dated to be 150 million years old and the rocks have grain of sizes between clay-sized and 1mm. The Morrison formation has inconsistent lateral thickness as it has thick layers and goes down to thin layers and has tightly compressed sediments. To why we believe the place was roamed with dinosaur as the Morrison formation is deposited near a flooded river or lake which have soft soil for dinosaur to implant dinosaur prints and the site itself is giving out radioactive which is from carnotite decays to uranium as the dinosaur bones are deposited with this element because its porous property, thus letting the ground water to passed through it. The Morrison formation have minerals such as hematite, quartz and clay and due to the iron and copper found in the formation, it causes paleosoil, a red-and-mauve-colored mudstone, to form in the middle section. The main event for the Morrison formation is the regression of sea level. Up next is the Dahkota sandstone, the 100-million-year old formation which with the sign of oscillating ripples indicate a beach front property. The Dahkota sandstone is consisted of quartz, hematite and clay and transgression of sea happened during that
