Who lived here before the Giants?

For the third consecutive year, UCMP participated in the Bay Area Science Festival at AT&T Park as one of several Science@Cal exhibitors. The November 2, 2013, festival drew more than 28,000 science fans and Lisa White, Tripti Bhattacharya, and volunteer CJ Dunford staffed a UCMP table. With a theme of "Who lived here before the Giants?," the UCMP fossil display and activities were a big hit with the little fans!

The 2014 UCMP Fossil Treasures Calendar is now available

March 2014 calendar spread

Examples of the scientific illustrator's art

Early this past year, as UCMP continued its efforts to catalog the museum's archival collections, a small collection of original scientific illustrations were rediscovered. These pieces represent the work of a number of talented scientific illustrators who produced images for the publications of UCMP curators, staff, and students between the years 1934 and 1991. All who saw these works were impressed by the skill, patience, and steady hand required to produce them. Therefore, it was decided that this art should be the focus of the 2014 calendar. Thumbnails of each month's primary illustrations can be seen below.

Contact Chris Mejia at cmejia@berkeley.edu or call 510-642-1821 to obtain your 2014 UCMP Fossil Treasures Calendar, a tribute to the museum's scientific illustrators. They're only $10 each (plus postage) and all proceeds support museum research, education, and outreach.

And for the collectors out there, a few copies of the 2013 UCMP Fossil Treasures Calendar are still available for a mere $2.

Recent Ph.D. grad Sarah Werning, now in a postdoctoral position at the State University of New York at Stony Brook, was a major contributor to a paper released today on ontogeny in Parasaurolophus, a Cretaceous hadrosaurid dinosaur notable for the hollow, bony tube on its skull. The study centers around a remarkable skeleton of a baby Parasaurolophus (nicknamed "Joe") discovered in 2009 by Kevin Terris, a student at The Webb Schools in Claremont, California, in exposures of the 75-million-year-old Kaiparowits Formation, Grand Staircase-Escalante National Monument, Utah. The Webb has been taking students to Grand Staircase-Escalante to prospect for and collect dinosaur bones for several years.

Werning did histologic studies of the six-foot-long specimen and found that the animal was not even one-year old when it died. Sarah reported that "Dinosaurs have yearly growth rings in their bone tissue, like trees. But we didn't see even one ring. That means it grew to a quarter of adult size [25 feet] in less than a year."

Three-dimensional scans of the entire skeleton were made and are freely accessible online. See the paper, along with the 3D scans, in the open-access journal PeerJ. Co-authors on the paper are Andrew Farke of the Raymond M. Alf Museum of Paleontology, Claremont, California, and Webb students Derek Chok, Annisa Herrero, and Brandon Scolieri.

A whale of a find

The upper Miocene-Pliocene Purisima Formation near Capitola, California, is well known among avid fossil collectors and popular with beachcombers. While this seaside shallow marine deposit contains rich assemblages of clams, snails and other invertebrates, fossil vertebrates such as whales, fishes, and birds are the most prized. Happily this is a case in which amateurs and scientists have often partnered to exchange fossils and report findings. Fossil hunters Frank Perry, Stan Jarocki, and Bobby Boessenecker recently donated several important fossils from the Purisima Formation to the UCMP: a five-million-year-old whale skull and two ear bones from dolphin-like marine mammals. Descriptions of these fossils were published in the journal Acta Paleontologica Polonica as reported by the San Francisco Chronicle.

Understanding Science is now in Portuguese

Você fala português? If so, you’ll be pleased to learn about Understanding Science’s new Portuguese translation, led by Unversidade de Lisboa Principal Researcher Nuno P. Barradas and his team. Nuno and colleagues recently promoted Understanding Science in Portuguese at a community science event in the town of Estremoz, east of Lisbon. Science on the Streets was organized by Portugal’s national agency for public awareness of science, Ciência Viva ("Living Science"), and the Understanding Science flowchart featured prominently in the display!

Barnosky interviewed about climate change

global changeTony Barnosky, UCMP Curator and Professor of Integrative Biology, discussed a consensus statement to world leaders regarding global change, Maintaining Humanity's Life Support Systems in the 21st Century, this past week in an interview by KQED Science Editor Craig Miller.

Barnosky has been working with the California Office of the Governor to promote science-based solutions to global change problems. With 15 other global change scientists he developed the scientific consensus statement, which has now found its way into a number of state, national, and international discussions about environmental solutions. Since the release of the statement in May, more than 1,000 scientists around the world have endorsed it. Join the scientists and add your name as an endorser of the statement.

Engaging the next generation of geoscientists

Most Earth scientists have vivid memories of their first geological field trip, but how many can say their first experience was as a high school student on a trip led by 15 professors, professional scientists, and college students?

Thirty lucky students from the Bay Area, El Paso, and New Orleans were selected to participate in a ten-day, geology-of-California field trip that started along the San Andreas Fault at Pt. Reyes National Seashore and ended at Yosemite National Park. Led by UCMP Assistant Director Lisa White as part of the METALS (Minority Education Through Traveling and Learning in the Sciences) program, the trip was supported by an NSF collaborative grant between San Francisco State University, University of Texas El Paso, and the University of New Orleans. High school students recruited from each of the participating cities came together on June 10-20, 2013, for a fast-paced field trip led by faculty, graduate students, and educators associated with those universities.

Lisa said, "Having directed the program for four years, my expectations for the student participants grow higher each year, and I am never disappointed. We create opportunities for the students to not only learn in a field setting but also to compete for awards by demonstrating an understanding of key concepts, making rock and fossil identifications, and producing outstanding field interpretations. The students, many of whom have spent little time outdoors or at the coast or in the mountains, have fun testing their endurance and enjoying learning in a natural setting."

The overriding goal of the METALS program is to raise awareness about the geosciences and to increase the numbers and diversity of students choosing academic paths in geoscience and related careers. What better way to showcase Earth science than through fun and exciting field work?

Fossil bridging with the Girl Scouts

What Bay Area event brings together 5,000 eager girls, 50 exhibitors and a walk across the Golden Gate Bridge? Girl Scout Bridging! On Saturday, May 11, Lisa White, UCMP Director of Education and Public Programs, and Erica Clites, Museum Scientist, attended the annual Girl Scout event at Crissy Field in the Presidio of San Francisco. The Bridging is a symbolic event recognizing the transition from the Junior level of Girl Scouting to Cadette, and the girls — representing troops throughout the western states — still had plenty of energy to learn about the history of life and engage with fossils following their bridge walk!

Marshall shows terrestrial mammal extinction due to Red Queen with new work published in Science

By studying 19 groups of Cenozoic mammals Charles Marshall and Tiago Quental tested and confirmed the Red Queen hypothesis. Red Queen is the hypothesis that states that groups must continue to adapt and evolve in response to their environments in order to survive. It's not just extinction events that threaten groups--it's also low rates of origination of new species. The new research (published in Science) shows that these mammal groups have experienced diversity declines in part due to their failure to keep pace with their deteriorating environments.

Warmer climates can lead to big lizards

A mounted modern lizard alongside the fossil jaw bones.

Pat Holroyd and co-authors describe a new species of giant lizard in the latest issue of Proceedings of the Royal Society B. The fossil jaw bones of this lizard have been in the UCMP collection since the 1970s, but it took a while for them to be recognized as something special. The specimens are from an herbivorous lizard that lived in the warm climate of Asia 40 million years ago. Dubbed Barbaturex morrisoni, this lizard was much bigger than the largest herbivorous lizards alive today. The unique traits of this lizard indicate that a warmer climate may have enabled gigantism via increased floral productivity and metabolic rates.
