What kind of dinosaur lived in Utah?

Why does Utah have so many dinosaurs?
The rising mountains in western Utah provided sediment, and the coast provided water to carry all that material, such that many creatures from these ancient ecosystems were buried quick enough to enter the fossil record.
Why does Utah have Red Rocks?
The red, brown, and yellow colors so prevalent in southern UT result from the presence of oxidized iron–that is iron that has undergone a chemical reaction upon exposure to air or oxygenated water. The iron oxides released from this process form a coating on the surface of the rock or rock grains containing the iron.
Were there T Rex in Utah?
‘The tipping point’: First T. rex mass death site in southern US, found in Utah, strengthens evidence of pack behavior. The Tyrannosaurus rex may not have been as solitary as we believed. In a groundbreaking discovery of the first T.

Is an Allosaurus bigger than a T Rex?
T. Rex adults were a significantly larger compared with allosaurus adults. An allosaurus adult was between 8.5 and 12m in length (28-39 ft), while the average T. Rex adult was about 12-15m long (40-50 ft).
Why are Utah mountains flat?
Erosion sculpts the flat-lying layers into picturesque buttes, mesas, and deep, narrow canyons. For hundreds of millions of years sediments have intermittently accumulated in and around seas, rivers, swamps, and deserts that once covered parts of what is now the Colorado Plateau.
What was Utah like 10000 years ago?
The climate 10,000 years ago was much different. Utah’s temperatures were cooler and it might have rained more often. Paleoindians camped along the shores of lakes and streams, including the Great Salt Lake, which was much larger and not yet salty.

The most prominent outcrops of this formation make up the capstone of The West Temple in Zion Canyon. Rain dissolves some of the iron oxide and thus streaks Zion’s cliffs red (the red streak seen on the Altar of Sacrifice is a famous example).
