Smoking Gun for the Permian Extinction?
New geological evidence now supports the theory that a very large (possibly 60 km in size) asteroid collided with the earth at the end of the Permian period. This impact was probably the leading cause for the extinction of nearly all life on earth at the end of the Permian.

The Stark Beauty of the Petrified Forest
Wide veins of red, tan, beige, white, black and pink course across the ground and penetrate the tabletop mesas and bad lands throughout the Petrified Forest. Trees turned to stone lie scattered where they fell millions of years ago. This is a unique place accented by psychedelic colors and rich in cultural, geologic, archeological and spiritual history. ###

Historic Background of Reptiles (Part 5)
The dinosaurs first appeared in the Triassic, some 200 million years ago. At the beginning they were not the giants one thinks of, but were mostly small, some no bigger than a chicken. Like a chicken, they were bipedal, walking or hopping about on their two hind legs.

Understanding Time and Rock Units in Geology
Geologists use three different units to help in their study of the history of the earth. Time units represent the continuous flow of time through geologic history, rock units represent the different lithologies found across the globe, and time-rock units represent all the rocks formed worldwide during a specific period of geologic time. This week we will examine these units and how they relate to each other.
