The KU Biodiversity Institute and Natural History Museum stand with our partners in the Spencer Museum of Art, The Commons and the Hall Center for the Humanities in their support of freedom of expression in academia and the contributions it brings to our society. Like them, we remain committed to engaged and inclusive dialogue with our communities. The following statement was distributed on July 13 by the Spencer Museum and The Commons:
We respect and welcome continued discussion of the artwork “Untitled (Flag 2)” by Josephine Meckseper, now on display inside the Spencer Museum of Art. Exhibition of the artwork, part of the Pledges of Allegiance project hosted by the Spencer Museum of Art and The Commons, will continue to fulfill our commitment to supporting art, ideas, and dialogue.
The Pledges of Allegiance series is organized by the nonprofit Creative Time, which asked 16 artists to create works, representing current issues of importance, to be exhibited and discussed at public and private institutions nationwide. Eleven of the 16 works have been displayed in front of The Commons on a new flag pole that was erected specifically for the exhibit. Support for this project and the associated events has come from private funds.
Themes of the artworks in the series include: peace, community, fear, cooperation, friendship, surveillance, government representation, and, among others, what it means to be an active citizen. The final work in the Pledges of Allegiance series is Meckseper’s abstract representation of the United States divided into two parts and a printed graphic of the American flag. Citing the diverse histories and perspectives of people in this nation, Meckseper uses the work to call attention to the nation’s divisions at a time when unity is needed.
Working with the Office of the Provost and other partners across campus, the Spencer Museum of Art, The Commons, the KU Natural History Museum, and the Hall Center for the Humanities will offer programs in the coming weeks and months that explore the issues and the responses raised by the artworks.

Paleontologists don’t necessarily find what they are looking for – even when they know where to look. But as a crew of KU paleontologists, students and volunteers discovered this summer, a disappointment in one location can yield surprising results somewhere else.
In June, a group led by Biodiversity Institute paleontologist David Burnham intended to return to the site where for two years they had excavated a Tyrannosaurus rex piece by piece. They hoped to build on the large femur they discovered last year, which belonged to a subadult female T. rex now on display at the KU Natural History Museum.
The formidable rock above the layer of fossils, or overburden, was difficult to remove, however. While the crew waited out several delays getting heavy equipment to the area, David directed the group to another site. They began to call it the “mystery theropod” site, home to what David said may be another, even younger, T. rex, or a dinosaur entirely new to science.
“The second site was discovered in our permit area during our last field season in 2016,” David said. “At that time, we found a fragmentary bone that looked interesting and made plans to return later to see if the site would yield more fossils.”
The mystery theropod site, near Jordan, Montana, proved to be much easier to dig than the first site. During the four weeks that crew members were there, they discovered more than 20 fossils along with dozens of bone fragments. These included three pedal unguals, or claws. The crew also unearthed a foot bones, and skull bones such as jaws with teeth, isolated teeth with roots, backbones and possible pectoral bones, ribs and parts of the pelvis.
“We don’t know what dinosaur it is yet, but we do know it’s a theropod—a carnivorous dinosaur,” David said. “The skull is over a half meter long.”
But in addition to all the fossil material from that site, plus clearing the original site of immense overburden, the crew also excavated the partial skeleton of a fossil bird. They found most of a leg, which had an articulated claw, and mixed in with the bird was a fossil crocodile skeleton. The crocodile had a partial skull, back bones and limb bones.
Bird fossils from this long ago are rare and therefore useful for unraveling bird evolution, Burnham said. The site was probably the remains of an ancient lake where the birds and crocodiles had lived.
Thanks to more than $15,000 in donations to the project -- including a lead contribution from John Weltman and Cliff Atkins of Boston, MA., the crew was able to obtain digging equipment, supplies such as plaster and glue, rent vehicles to transport workers to and from the sites, book hotel rooms, purchase food, and even hire a backhoe operator for removing overburden off the original T. rex site.
Donors also provided support for students to work in the laboratory for the coming months to clean, prepare and examine the fossils they brought back to KU, as well as pay for a series of scientific tests on the bones and rocks from the T. rex. The preliminary tests have shown that KU’s T. rex is probably the geologically oldest ever discovered and that the long bones contained calcium—a preliminary indicator it was a female capable of laying eggs.
Donors to the project and the public are invited to learn more about the work at “Tooth & Claw,” 6:30 pm Thursday, Sept. 14. The event will include a talk by David Burnham, food, and drinks available for purchase. Attendees will also have the chance to see not only the new mystery theropod fossils but also a new young T. rex on loan to the museum through December, and see new paleontology exhibits such as the recently completed paleogarden. The event is free but tickets are required and can be reserved here.

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.
Archived posts from the group are available here.
While Rudy Serbet, Carla Harper, Erik Gulbranson, Lauren Michel and colleagues have returned to their universities to continue their research, the Antarctic Sun has meanwhile compiled this video about their research in Antarctica.
Before you can leave for the field, the US Antarctic Program (USAP) makes sure you are ready and competent in the science of safety. In order to get ready, G-496 sat through a half-day class on safety, taught by one of the resident guides Suz. She is a great teacher who has been down here for years. She covers things like how to stay warm, preventing frostbite and hypothermia, basic knot skills, and how to set up and use a camping stove. She also talks a little about helicopter safety.
Then the next day, as a group we went out in a haglund (see below) with Suz and our mountaineer Dave Buchanan for a full intense day of practical field safety. Photo by Ignacio Escapa
First we learned glacier travel which includes how to walk on ice and snow and how to use crampons and ice axes . Photo by Ignacio Escapa
Then we learned how to set up the tents we would be using in the field, as a team. This included anchoring the tent into the snow using a “dead man’s” anchor. After we got the tents set up, everyone who had been to Antarctica recently left for the warm of McMurdo and four of us (Charlies, Ignacio, Carla, and myself) stayed behind.
Next we learned how to build an ice-wall to protect the camp from incoming wind. Photo by Ignacio Escapa
We set up the kitchen, and made dinner. Suz left us to stay in the warmth of the instructors hunt while we fell asleep out on the Ross shelf in our tents.
The next morning we woke up to wind, which made everything more difficult. We had to, as a group, take down camp, pack everything away and be ready for Suz to pick us up. However, because of the wind and it getting colder that night, the haglund wouldn’t start. So we had to carry out everything on a sled to the road, were we could be picked up by a shuttle and return to the warmth of buildings, McMurdo and the rest of our group. -Lauren Michel
We have been delayed getting out to the field for a week now because of weather. When the clouds are
low or air pressure is bad, helicopters can’t take off, which is what has happened this week. A big part
of getting ready for the field in Antarctica is hurry up and wait. We landed and were thrown into
classes, field safety, getting food and sleep kits, and gear organized. We had to retrofit the rock boxes
so they wouldn’t fall apart. You have to get all of this done in the few days before you are trying to
leave for field work. If you are delayed, there is a lot of sitting around reading papers and trying not to
get to antsy for the field. One of the nice things about McMurdo is the great hiking you can do to keep
you busy and see the area a bit. This is what we have been doing this week.
Adjacent to McMurdo is the hut Robert Falcon Scott built in 1902 for his 1901-1904 polar expedition.
It’s just a short hike to visit the hut.

good opportunities for some wildlife viewings. Photo by Lauren Michel.

Another outdoor adventure is going to the observation tube, which is out in the middle of the Ross Sea.
You can crawl down and see jellyfish and ocean wildlife. Here's Erik heading into the observation tube. Photo by Lauren Michel.
McMurdo Station and the New Zealand, Scott Base are situated on a volcanic island in the middle of the Ross Sea. The two stations are close together, separated by a road with a hill, so you can walk along the road to Scott Base if you want. The hike to Scott Base with Observation Hill in the background.

When we got to Scott Base we were greeted with the Ross Sea ice coming up on Ross Island. It was one of the most beautiful things I’ve ever seen. Photo by Lauren Michel
On your way to Scott Base is the last of the hikes I’ve done, it’s called Observation Hill, or Ob Hill for short. This hill overlooks all of McMurdo and has a gigantic cross on top, that was erected in 1913 to commemorate Robert Falcon Scott’s party who died trying to reach the South Pole.

Before we even set off for Antarctica, 4 of us (Erik Gulbranson, Rudy Serbet, Ignacio Escapa and myself) made a reconnaissance trip to Curio Bay, New Zealand. Curio Bay is close to the southernmost part of the south island of New Zealand and is famous for the preservation of a 180 million year old fossil forest. Because what we are studying in Antarctica is roughly time equivalent, and Antarctica and New Zealand were close together in the southern part of Pangaea during this time, we thought it would be interestingto go study the forest of Curio Bay. Then we can compare what we are seeing in Curio Bay to what we are seeing in Antarctica.
What we found was quite interesting and a great start to the field season. Many papers have described forests at Curio Bay as being in situ with some of the logs may having been transported on a river. What we realized was that the forest of Curio Bay is actually 2 or 3 separate forests, with tree stumps now preserved in silica (or chert). Imagine a tree being dunked in epoxy and solidifying: this is the type of preservation process, except in stead of epoxy it is silica (quartz) that provides the cementing agent.
All of the knobs sticking up are fossilized tree stump casts. This area is a preserved area by the New Zealand government, which is similar to Petrified Forest National Park in the US; you can’t take any of the tree stumps casts, but you can study them! Erik is interested in what fossil trees record and can tell us about past climate changes. One of the ways he does this is through very carefully studying the tree rings that are now preserved in silica. He can take careful measurements of the widths of the tree rings using calipers and high-resolution digital images to a number of things: (1) cross date the trees to figure out which of the trees were growing together at the same time, (2) create a long (100 years or more) timeline of wood growth year-by-year for these trees that are ~180 million years old, and (3) interpret the variation in ring width over that long timescale (100 years or more) to interpret paleoclimate. Rudy and Ignacio (Nacho) are paleobotanists and are experts in plants of this time period and the evolution of plants over geologic time; they are also excellent field geologists/paleontologists. Lauren’s specialty is the study of fossil soils (paleosols) throughout geologic time.
Since Curio Bay is tidally influenced, time was an issue. We divided up the tasks with Rudy doing reconnaissance to find the best preserved stumps. Nacho would take careful photographs that Erik can study later, Erik would measure the rings he could get to with his calipers and I would take notes. We ended the day with the best discovery of all, a rare yellow-eyed penguin. A great end to the start of our field season! - Lauren Michel and Erik Gulbranson
For people that are going into the ‘deep field,’ i.e., people like our field party that will go away from the station and camp out somewhere, there is a food warehouse where you pack the food you’ll need for your field stay. If you are not very far away from McMurdo Station, you can get resupplied with food if a helicopter is going that way (see note above about frozen food). Since we don’t hike into our camping sites, we can take frozen, canned, and dried food.
For people staying in McMurdo, there is a cafeteria where everyone eats and the food is plentiful and very good. They say you burn almost 3000 calories/day just keeping warm, so food is very important for your survival!
There is a food warehouse, where you pack food for the field (see photo at left). Because it’s so cold, usually around –30°F, it’s possible to take frozen food out into the field and leave it in boxes outside your tents. Since there are no land animals in Antarctica (except for a wingless fly on the Antarctic Peninsula), there’s no problem with leaving food outside! - Co-PI and Curator, Edith Taylor
The US National Science Foundation provides almost all the clothing, food, and camping gear you will need in Antarctica. There is a clothing warehouse in Christchurch, New Zealand (the place we fly from to reach continental Antarctica), where each field party member tries on the cold weather gear before they go to the field.
In McMurdo, your gear is waiting for you (put together by workers that are there during the winter) to check out and make sure it is what you need, e.g., you check your tents to make sure there are no holes (see below).
Why red coats? Maybe they chose red because it is easy to see whether you're on rocks or ice and snow. There is probably a safety factor of the "dumb beakers" (what the support people, especially the military folks, used to call us scientists!) getting lost somewhere! - Co-PI and Curator, Edith Taylor
