Imagine over 3,000 adults in San Francisco’s California Academy of Sciences (Cal Academy) for a night of fun special exhibits, drinks, and a serious science social. Now imagine it every Thursday. On July 23rd a dinosaur-themed Cal Academy NightLife event called upon volunteers from UCMP to showcase and explain the mysteries of these monsters beside their contemporary chews.
The NightLife also featured a tour of Cal Academy’s library archives about the historic “Bone Wars” between Victorian paleontologists Othniel Charles Marsh and Edward Drinker Cope and a showing of the 1993 classic Jurassic Park in the Tusher African Hall. Indeed, there was something uncannily familiar about watching the Dilophosaurus scene from Jurassic Park amongst stuffed African lions and cheetahs, who had also certainly taken their fair share of prey during life.
The event runs every Thursday from 6-10pm and requires a 21+ photo ID for entry. Stay tuned for the next time UCMP crosses the bay for another paleo-themed NightLife gathering!
Fifty-six million years ago the Earth underwent a dramatic warming event, with temperatures increasing by as much as 7° Celsius over a span of just 100,000 years. Many mammals responded to this temperature increase by becoming much smaller. How these changes happened, however, is poorly understood. Identifying and measuring the mechanisms that drove these changes was the focus of a new study by University of California Museum of Paleontology researchers Brian Rankin and Pat Holroyd, and colleagues from University of Calgary and Western University of Health Sciences.
Lead author Brian Rankin, the newest postdoctoral scholar of University of California Museum of Paleontology, explains "When temperatures get warmer, we see a wide range of mammals become smaller. Determining what evolutionary processes are responsible for these changes and how much each contribute to this pattern has been very uncertain. We chose the evolution of mammals at the Paleocene-Eocene boundary because it is a time of dramatic global warming when many different types of animals became dwarfed and the fossil record of this time is incredibly rich."
In a new paper published in Proceedings of the Royal Society B, these researchers present a new method to separate and quantify body size change due to selective extinction vs. change within lineages to determine which is the most important way in which evolution takes place during times of global warming. They found that that some evolutionary mechanisms (i.e., species selection) might act differently during global warming events, favoring mammals that increase in size rather than decrease. The methods developed in the paper can now be broadly applied to look at evolutionary change during other times of global change.
UCMP's partnership with Point Reyes National Seashore (National Park Service) has resulted in the discovery and collection of an important marine mammal specimen. This specimen is currently being prepared by UCMP Research Associate Robert Boessenecker, and will be reposited at UCMP. Lillian Pearson, a Geoscientist-in-the-Park intern, is setting up protocols for the long-term monitoring of paleontological resources (fossils) at Point Reyes. Erica Clites did this type of work for the National Park Service before coming to UCMP, and has been advising Lillian on the project. For more information, read the full story.
On June 15, UCMP Curator and Integrative Biology Professor Tony Barnosky met with Governor Jerry Brown, Executive Secretary of the UN Framework Convention on Climate Change Christiana Figueres, and California climatologists at the Los Angeles County Museum of Natural History to discuss global warming and the consequences of failing to deal with it.
At a press conference following the meeting, Brown expressed his desire to reduce California’s greenhouse gas emissions by 40 per cent over the next 15 years and spoke of legislation mandating that 50 per cent of the State’s electricity come from renewable sources by 2050.
At the end of November, representatives from some 195 countries will gather in Paris for a UN Climate Change Conference in the hope of forging international agreements to limit greenhouse gases and combat climate change.
Every May for the past 30 years or so, the Girl Scouts of Northern California have celebrated the advancement of their scouts from Junior to Cadette status by a symbolic walk across the Golden Gate Bridge. Following this year’s May 2 event, the scouts continued on to Crissy Field where they enjoyed entertainment and information booths. And UCMP was there to celebrate with the scouts.
For the third year in a row, UCMP hosted a table staffed by an enthusiastic crew that included graduate student (and former Dutch girl scout) Renske Kirchholtes, undergraduates Gina Hwang and Alexis Williams, and Museum Scientist Erica Clites. The Girl Scouts and their parents enjoyed talking with current UC Berkeley students and seeing women role models.
Annual field trips used to be something of a tradition at UCMP, but that tradition faded once the Department of Paleontology merged with other units to become the Department of Integrative Biology in 1989. In recent years, former UCMP Director Jere Lipps organized and led three field trips: Baja in 2001, southern California in 2008, and Oregon in 2009. And now two of UCMP’s newest curators, Assistant Professors Seth Finnegan and Cindy Looy, are trying to revive the annual field trip tradition. Seth organized and led a trip to the Kettleman Hills and Death Valley in 2014, and this year, he and Cindy led one to southern California during Spring Break, March 21-28.
On March 21, Seth, Cindy, three UCMP staff (Lisa White, Dave Smith, and Erica Clites), and 11 grad students headed south from Berkeley, with their first stop being a locality south of Soledad along Arroyo Seco Canyon in Monterey County. Here, the group had their first look at the rocks of the extensive Miocene Monterey Formation and found pea crabs, bivalves, and brachiopods. The group would visit more exposures of the Monterey Formation along the California coast at Gaviota State Park and El Capitan State Beach, west of Santa Barbara and even as far south as Newport Bay.
At Piru Gorge, just off I-5 south of Tejon Pass, an attempt was made to relocate some plant localities reported by UCMP alum Daniel Axelrod (A.B., 1933; M.A., 1936; Ph.D., 1938), but without success. East of the gorge and the highway, some road cuts exhibiting nice geological features (cross bedding, ripple marks, etc.) were examined.
Jere Lipps current Director of The Cooper Center, the fossil repository for Orange County gave the group a tour of the Cooper facility. Afterwards, Jere took the group to a number of interesting localities in the Newport Bay area, including a visit to the Upper Newport Bay Nature Preserve with outstanding views of marine terraces. At the end of the day, Jere and Susie Lipps had the group to their home for a barbecue.
Anza-Borrego Desert State Park, east of San Diego, was the next stop. The group spent two days looking at the geology exposed at Split Mountain and along Fish Creek Wash in the southeastern corner of the park. The rocks along the wash told some very interesting stories. Moving from east to west, the group examined cobble-filled layers believed to have been deposited by flash floods. Farther on, the rocks showed where an underwater landslide buckled unlithified ocean sediments. Close to the western end of Split Mountain, a series of turbidites underwater sediment flows that result from slope failures at shelf margins or the distal edges of large river deltas were observed. Even farther west down the wash, many layers of nearly equal thickness were suggestive of sands deposited out on a vast river delta of shallow slope.
From Anza, the group headed to the Sonny Bono Salton Sea National Wildlife Refuge on the southeast shore of the Salton Sea. Here the group had an initial look at the lake’s beaches covered with dead barnacles and the bones of fish and birds. After a stop to admire some mud volcanoes near one of the 11 geothermal power plants located around the southern end of the Salton Sea, the group headed to the hills above Mecca at the north end of the lake. The group spent its final night in Painted Canyon after taking a hike through it and an adjoining slot canyon.
After a morning look at some roadside exposures of delta deposits, the group made the long drive back to Berkeley. All participants thoroughly enjoyed the trip and Seth and Cindy are already pondering where to go next year. Will it be the Great Basin? Channel Islands? Italy anyone?
The Bearded Lady Project: Changing the Face of Science came to the UCMP in February, one of many stops in a photographic journey made by documentary film makers seeking to educate the public on gender inequities in geoscience fields, particularly in paleontology. Women of the UCMP sat for portraits that will become part of a photography series intended to celebrate adventurous women who are true pioneers in the fields. See if you can recognize some of your favorite women of the UCMP!
If you have taken the elevator to the top of Sather Tower, aka the Campanile, perhaps you've heard that some of the floors of the tower are filled with fossils. This is not a campus myth, it's fact!
The Campanile is celebrating its 100th anniversary this year and its very first occupants moving in before the tower was even completed were fossils. At that time, the museum and Department of Paleontology were in Bacon Hall, just east of the Campanile, so as a storage facility, the tower was conveniently located. Although the museum has moved several times over the past century, the fossils in the Campanile have not.
Some of the first fossils to be moved into the tower were vertebrate bones from John C. Merriam's excavations at the Rancho La Brea tar pits. These bones, collected prior to 1914, occupy four of the five floors devoted to fossil storage. But the Campanile houses several other collections too. There are bones collected in the 1930s from asphalt deposits in McKittrick (about halfway between San Luis Obispo and Bakersfield) and nearby Maricopa; mammoth bones, teeth, tusks, and other miscellaneous Pleistocene fossils; modern whale bones; a few blocks containing ribs of the plesiosaur Hydrotherosaurus alexandrae; crates containing plaster casts of dinosaur footprints and trackways that were made by Sam Welles while doing field work in the Kayenta Formation of Arizona; petrified wood from the Petrified Forest; fossil plants; invertebrate fossils, including collections moved to the Campanile from McCone Hall and some from Triassic rocks in Nevada; Upper Cretaceous leaves from Bryce Canyon, Utah; oil company collections of microfossils (bulk samples) and invertebrates; casts of mastodont skulls; an ichthyosaur skull; some sculptural reconstructions (including a glyptodont); and cases of reprints. A conservative estimate of the number of fossils stored in the Campanile, excluding the microfossils, is 300,000.
During this year-long celebration of the Campanile, it is only fitting that the fossils housed there receive some attention too. We will periodically post blogs throughout the year to discuss some of the ongoing research projects that involve the Campanile's fossils. For instance, UCMP Curator and Associate Professor of Integrative Biology Leslea Hlusko and her lab have two projects underway and Eric Holt, an undergrad in Tony Barnosky's lab, is looking at wolf morphometrics. And back in September we announced the grant award from the Institute of Museum and Library Services to curate the Campanile's McKittrick fossils. To date, more than 2,500 specimens have been cleaned and cataloged, and more than 500 images of 273 specimens have been added to CalPhotos.
Stay tuned for more about the Campanile's fossil treasures!
On November 1, UCMP participated in Discovery Days at AT&T Park, the closing event of the annual Bay Area Science Festival. The museum has been a Science@Cal exhibitor at the Festival for four years running. This year, over 30,000 people enjoyed 200 free activities and exhibits at the Festival, a “science extravaganza.” The Festival is meant to entertain and inspire; it’s where visitors can unleash their inner scientist.
