Nearly four months after the KU Antarctica team returned to campus, the 5,000 pounds of fossil material they collected in Antarctica will arrive at KU on Monday, April 13.
Staff and students will start unloading 50-60 wooden crates of material that is 260 to 180 million years old, from the Permian and Jurassic periods.
Although most people think of Antarctica as a barren, cold environment, 200 million years ago it was a land of lush forest – a forest that now permineralized can yield clues to the climate change of the past, and how plants today may react to climate change as well.
The fossil material will help scientists study floral changes during the Jurassic in the Transantarctic Mountains of Antarctica.
“This research is important in understanding what climate and environment was like at the poles during one of Earth’s past greenhouse climates and how plants responded to both climate changes and instantaneous disruptions through the rise of volcanoes,” said Rudy Serbet, collection manager of paleobotany at KU Biodiversity Institute and a team leader for the trip. “These sorts of times and environmental stresses are key to understanding how current climate change may effect high latitude plants.”
During the seven weeks they were in Antarctica, the group took several camping field trips “out to the ice,” including the Odell Glacier area and the Allan Hills.
No staff or students have seen the material in the intervening months as it made its way from Antarctica to California to Kansas.
"Today is like Christmas in April,” said Paleobotany Curator Edith Taylor, lead PI on the National Science Foundation grant that funded the research.

PhD student Scott Travers recently shared an article from the Solomon Star featuring a 2 week biodiversity research expedition he took part in while leading his own expedition to the island nation. This two week trip was organized by Ecological Solutions Solomon Islands and along with Travers was composed of a multinational team representing a number of fields in the biosciences.
Our driver, Leroy, slammed on the brakes. The large Bedford truck behind us carrying our gear and most of our crew ran into a patch of think mud and was now sunk up to its axel and listing to one side. Up to now, our three-truck caravan had snaked its way towards to our first base camp without any problems.
The Panorama was full of families today creating their own diorama. And what better place to do it than the biggest diorama any of them had ever seen? Everyone created a scene in their museum boxes — favorite scenes from books, nature, their family.
One of the challenges has been to figure out how to plug in the special vacuum units that the conservation team is using. Unlike a home, these can’t be plugged in and then drag a cord across the floor. A cord could damage the plants, or even snag an animal mount.
To solve this puzzle, exhibits director Bruce Scherting went up into the attic above the Panorama. Using outlets near the Panorama’s upper lights, he plugged in extension cords and fed them thirty feet to the floor. But that led to another issue: the cords might chip the paint at the top of the exhibit if staff pulled them along the surface. Pieces of hose, cut into two-foot lengths and eased over the cords turned out to be the perfect solution. The hoses hooked on the lip of the exhibit and dangled the cords to the floor, where sandbags held them in place.
One of the most challenging aspects of working inside the museum’s Panorama exhibit is its fragility. In fact, Ron Harvey has described it as “working inside a painting.” But instead of straddling the brushstrokes of Van Gogh, the assessment team is carefully maneuvering across plaster “rocks,” along narrow foot paths, and between animal mounts.
Nancy Bixler described the work as physically demanding and requiring a three-dimensional consciousness.
“It looks easy from the outside, but it is a huge challenge,” she said. “You can’t lean on anything and you must keep your balance as you move around the animals and plants.”
The team wears Tyvek suits, booties, and respirators over their street clothes to protect against particles in the air that may include arsenic or lead. With every step, they must assess where their feet will fall, and make sure that they don’t step on the dried grasses — one misstep and the grasses turn to dust.
The contorted positions would make anyone sore at the end of the day. Perhaps we should consider yoga sessions in the Panorama to stretch out at the end of the day?
Today we welcomed the first members of the our conservation assessment team to the museum. There have been meetings about safety, protocols and troubleshooting. The team will be led by Ronald Harvey, owner of Tuckerbrook Conservation of Lincolnville, Maine. He and his associates, together with KU museum studies students and volunteers, will survey the state of each of the Panorama’s animal mounts, plants and backgrounds. They will lightly clean the animals, which have endured years of exposure to fluctuating temperature, humidity and light. The onsite assessment is scheduled to be completed Friday, April 4, and will result in a report about the exhibit’s condition by July.
