Volunteers Have Fossil Field Find on Forests and Grasslands

Paleontologist Barbara Beasley’s voice filled with excitement as she described a recent dinosaur find on the Thunder Basin National Grassland in northeastern Wyoming.

“This was a once-in-a-lifetime experience for our Passport in Time volunteers,” she said. “Mother Nature preserved and stored this treasure for more than 65 million years.”

Beasley led a group of 22 volunteers on a fossil excavation project at the Alkali Divide Paleontological Special Interest Area where volunteer Tom Ludwig found the nearly three-foot Triceratops horn.

The group was not expecting to find any large fossils at the site, so everyone brought only small bags to collect their findings. Called a micro-vertebrate accumulation by scientists, the site typically offers up fossils the size of a fist or smaller.

“This herbivorous dinosaur’s 31-inch brow horn is remarkably intact and very well preserved,” said Beasley. “All volunteers worked eagerly to completely unearth this paleo-prize.”

The plant-eating Triceratops – a skeletal mount has been on display at the Smithsonian Museum of Natural History since 1905 – may have been 30 feet long, with two large brow horns and a smaller horn on its snout. When this creature died 65 million years ago during the late Cretaceous, eastern Wyoming was a tropical environment.

“It’s very exciting…applying everything I’ve learned,” said Tirzah Abbott, a first-time dino-digger, paleontology geo-database technician and recent Geology graduate from Beloit College in Wisconsin. “I’m excited to be part of the excavation and preparation (of this fossil).”

Passport in Time is a Forest Service volunteer archaeology, paleontology, and historic preservation program. Through this program, students and volunteers get the opportunity to go in the field and work shoulder-to-shoulder with professional Forest Service archaeologists, paleontologists and historians on a wide variety of activities throughout the U.S.

    Is the Forest Service doing this volunteer program anywhere in Nevada?

  2. Ben [USDA Moderator] says:

    Thanks for your question. Our national forest and grassland units schedule their work depending on current needs, goals and other logistical concerns. Contact the volunteer coordinator at your favorite forest or grassland and let them know you are interested in helping when there are opportunities. You also might want to check the agency’s Passport in Time, a volunteer archaeology and historic preservation program. The program’s website includes a list of current projects, which changes throughout the year. As of today, there is one project listed: McMillenville, Part XII: The Last Hurrah!, which is on the Tonto National Forest about 16 miles from Globe, Ariz. Ten volunteers are needed to help complete documentation of the site, which has roots in prehistoric times and more modern-day historical connections that date back to 1882. Applications are due Jan. 20; the work is scheduled for Feb. 24-28.
