Did T. rex live in North America?
rex lived in the species’ native North America, possibly as far north as Alaska and as far south as Mexico, over a two- to three-million-year timespan.
Did T. rex live in Alaska?
A great discovery came in a small package for paleontologists who’ve unearthed a new species of tiny tyrannosaur in northern Alaska. Dubbed Nanuqsaurus hoglundi, the polar pygmy measured about 20 feet (6 meters) long, about half the size of its close relative Tyrannosaurus rex.
Has a full T. rex been found?
They turn out to be part of the largest-ever Tyrannosaurus rex skeleton ever discovered, a 65 million-year-old specimen dubbed Sue, after its discoverer. Amazingly, Sue’s skeleton was over 90 percent complete, and the bones were extremely well-preserved.
Was Utah under the ocean?
While today it’s a desert – dry as a bone – for hundreds of millions of years, starting around 570 million B.C., western Utah was under the ocean. California and Nevada weren’t around, and the west coast of North America ran right through our now-desert state.
Are there fossils in Salt Lake?
The Great Salt Lake is a small remnant of ancient Lake Bonneville. Quaternary fossil vertebrates include saber-toothed cats, short-faced bears, giant ground sloths, bison, and musk ox, among many others.
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.
When did dinosaurs live in Utah?
Early Cretaceous dinosaur fossils are found in Utah in the Cedar Mountain Formation, which dates to about 125-98 million years ago. This rock unit overlies the Morrison Formation, but represents more time and contains several entirely different faunas or groups of dinosaurs.
Does Utah have a lot of fossils?
Paleontology in Utah refers to paleontological research occurring within or conducted by people from the U.S. state of Utah. Utah has a rich fossil record spanning almost all of the geologic column.

Can the dinosaurs come back?
“The problem with dinosaurs is that the oldest DNA that we have in the fossil record is about a million years old, and dinosaurs died out 66 million years ago.” This is a problem because while some soft tissues and proteins can be preserved over large geologic timescales, DNA, as far as scientists know, cannot.
Did T. rex have any predators?
The new dinosaur, dubbed Siats meekerorum, is part of a group of giant predators known as carcharodontosaurs, and it’s only the second of this group to be discovered in North America.
