Ancient Plant Life
Although this area was a desert, the oases scattered among the dunes allowed some plants to survive. It is extremely difficult to preserve plants in a desert environment. To preserve something as a fossil, it must be buried as soon as possible. In a desert, the heat, sand, and wind tend to destroy plant remains so soon after they die that there is no time to bury them.

The other plant paleontologists have identified is a sphenophyte, or horsetail. These plants usually grow in wet areas, so if they were present in the desert, they were probably clustered in the wetter interdune areas. Horsetails consist of a single stem with needle-like leaves at regular intervals. At the joints where the needles are placed, there is usually a rigid ring in the stem.

Other Plant-Like Life
Paleontologists have also found laminated (or layered) carbonates. These are formed when sediment sticks to a mat of cyanobacteria. (These tiny organisms are not plants, although they are sometimes inaccurately referred to as "blue-green algae.") Layers like these are described as stromatolitic, and they only form in standing water. In one place at least, then, there was actually water above the surface.
Did You Know?
Paleontologist Earl Douglass first came to Utah looking for mammal fossils. He returned in 1909 and discovered an immense deposit of dinosaur bones, now protected at Dinosaur National Monument. Although made famous by dinosaurs, Douglass died preferring his beloved mammal fossils over dinosaurs.
