Explore the geological and paleontological diversity of Northeastern Arizona this fall as part of a unique geology course at Northland Pioneer College’s Show Low – White Mountain Campus focusing on the ecology, physiology and basic scientific methods used in researching dinosaurs.
NPC is the only community college in Arizona to offer an undergraduate paleontology course about dinosaurs. NPC Biology Professor Dr. David Smith and his colleague, paleontologist Doug Wolfe, will team teach the Geology course (GEO 203 – Dinosaurs) on Tuesdays and Thursdays, August 27 through December 12, 1 to 3:44 p.m. The four-credit course will transfer as a science elective into the paleontology programs at Northern Arizona University and the University of Arizona.
Registration is currently underway for the fall semester. Most classes begin the week of August 26. Tuition is $77 per credit hour plus a $40 course fee. A $45 Media Fee is charged for students carrying 3 or more credits.
Dr. Smith has expanded the course this fall to four credits to allow more time to cover the wealth of scientific research available. Learning from instructors Smith and Wolfe, students will apply biological and paleontology concepts and develop a field notebook outlining the bones, nervous and muscular systems of dinosaurs. Students will also study the origin and evolution of birds, the concept of extinction and basic scientific methods, including dissection of modern-day birds. Many scientists consider modern-day birds as descendants of dinosaurs. Best of all, students will get a chance to explore various local rock formations, “right under our feet,” notes Wolfe. “I’m excited about NPC’s course that will hopefully spark additional interest in the paleontology and geology fields,” he adds.
Dr. Smith, an NPC professor since 2005, specializes in vertebrate paleontology. He has been collaborating with Wolfe on digital imaging of the braincase of both Zuniceratops and Nothronychus. “Our study shows the Nothronychus was very sensitive to very low frequencies, such as those from approaching storm systems, although they probably did not emit sounds in those frequencies,” remarks Smith. Scientists, including Smith, are now starting to focus on the arm structure, with early indications Nothronychus was a possible swimmer.
Wolfe’s training in micropaleontology and biostratigraphy led him to the Zuni Basin along the Arizona/New Mexico border. Working as a consultant for the U.S. Geological Survey, he re-dated many of the rock formations in that region, as well as on the Little Colorado Plateau. While exploring the Zuni Basin with a film crew, Wolfe noticed dozens of bone fragments, weathered out by a nasty thunderstorm the previous week. “One fit neatly onto a bone sticking out of the hill,” recalls Wolfe. The site became known as the Haystack Butte Bonebed.
The scientific name given to the discovery was Zuniceratops christopheri – honoring the Zuni tribe and Wolfe’s son Christopher, who was 7 years old at the time, who picked up the first fragment from the horn-core. “We recovered a few hundred bones over several years from that site, mostly Zuniceratops, the oldest ‘horned’ dinosaur in North America, an early ancestor of Triceratops.”
Eventually, Wolfe realized he had bones other than from Zuniceratops that were very similar to Asian Therizinosaurs. After collecting more evidence with Utah State Paleontologist Dr. James Kirkland, the find was named Nothronychus (nahth-ROH-nye-KUSS), the first Therizinosaur found outside of Asia. Nothronychus was believed to be a biped plant-eater standing about 10 – 12 feet high and weighing nearly a ton.
Wolfe, his wife Hazel and son Christopher operate the White Mountain Dinosaur Exploration Center (WMDEC) in Springerville and routinely partner with university field teams recovering fossils in the region. The WMDEC, open most Thursdays through Saturday, features numerous specimens and exhibits, including a photo of a three-toed track discovered by Wolfe nearly a decade ago recording a pack of smaller carnivorous dinosaurs possibly hunting a larger plant-eater.
In addition to teaching at NPC, Smith and Wolfe are planning to explore major dinosaur fossil sites in China, Mongolia and Russia, with their findings to be published in a future textbook by Indiana University Press.
