In The Moment ... October 15, 2019 Show 679 Hour 1

After death, animals continue to play an essential role in the ecological process.

Dr. Sarah Keenan, a paleontologist and Assistant Professor of Geology and Geological Engineering at South Dakota School of Mines and Technology explains the process Tuesday evening during her STEAM Cafe presentation, Life After Death: Ecological Impacts of Animal Decomposition.

STEAM Cafe is hosted by the School of Mines and South Dakota Public Broadcasting at 6:00 p.m. at Hay Camp Brewing in Rapid City.

The South Dakota School of Mines is teaming up with the US Forest Service to clean, prepare and catalogue fossils collected over 30 years. The collaboration is part of the the Passport in Time Project, a conservation program intended to find and preserve paleontological and archeological specimens on federal land.

Dr. Barbara Beasley is one of only two paleontologists working for the Forest Service.  She works out of Chadron and manages paleontological projects in the northern half of the United States.

A group of fossils from four triceratops found in Wyoming could change what scientists know about the dinosaurs’ behavior.

Arthur Haas was one of two ranchers who found a fossil but didn’t learn until many years later that it was a unique genus of aquatic reptile.  The Haas family had the honor of naming it.  It’s now on display now at the Adams Museum and it’s SDPB’s Images of the Past feature this week.

Darrel Nelson, Deadwood History Inc., Exhibits Director, and Bill Haas, the grandson of a man who found a plesiosaur fossil near Belle Fourche in 1934, join Dakota Midday to talk aboutt the discovery, the artifact, and the naming of Pahasapasaurus haasi.

New research on a fossil discovered 40 years ago is adding to the understanding of a species of dinosaur that once roamed South Dakota.
The Dakotadon lakotaensis is a plant eating dinosaur that can be found in a layer of rock called the Lakota Formation.     If you live on the hogback ridge that circles the Black Hills, it’s likely you had them in your own yard between 110 and 130 million years ago.

More than 26,000 years ago at the Mammoth Site,  large Columbian and woolly mammoths were trapped in a large sinkhole and died. Their remains were buried and undisturbed for centuries until bones were discovered during excavation for a subdivision in 1974. Since then, 61 mammoths have been identified – 58 Columbian and 3 woolly mammoths. Remains of giant, short-faced bear, camel, llama, prairie dog, wolf and fish have also been uncovered.

"Stubby" The Triceratops With Broken Horns

If you want to know how many horns a Triceratops has just ask an average first grader—they will tell you, three.

But a nine foot long fossil skull of a Triceratops found in Montana is missing its third horn, normally found on the nose, and paleontologists at the Black Hills Institute of Geological Research are probing the mystery.

Sue the Tyrannosaurus Rex discovered in South Dakota in 1990 was 40 feet long and one of the largest predatory dinosaurs. But a century ago, paleontologists found fossils of an even bigger dinosaur on the edge of the Sahara Desert, the Spinosaurus. The fossils were completely destroyed in a World War Two allied bombing raid, leaving the dinosaur something of a mystery and not as familiar as the T. Rex.
