A first: Sauropod bones found in Ethiopia!

Assistant Director Mark Goodwin and his project collaborators (see Feb. 1 blog post) made a surprising discovery while collecting microvertebrates, turtles, and fish.  Within a small area of exposure in the Late Jurassic Agula Shale in the Tigray Province, just south of Mekele, Ethiopia, were the first sauropod dinosaurs ever reported from Ethiopia!

The team found mostly partial bones and bone fragments, and the local school kids delighted in holding Ethiopia's first sauropod dinosaur bones.

In December 2015 UCMP faculty curator Tony Barnosky and Stanford paleoecologist Liz Hadly attended The United Nations Conference on Climate Change to premiere a movie opening in Paris. The movie, Demain, was inspired by the 21-authored study that produced a 2012 Nature paper on tipping points. The film opens with Tony and Liz summarizing global change issues facing the world today.

Tony states, "the movie is all about solutions and is very uplifting." It features solutions being implemented in San Francisco and Oakland, in addition to many other places around the world. It was produced by and stars Mélanie Laurent, a well-known French actress, and Cyril Dion. The movie is getting rave reviews in Europe and the English version Tomorrow (see video) is anticipated to be released in the USA in the spring.

The Anthropocene has come of age

industryResearch by Faculty Curator and Professor Tony Barnosky and the Anthropocene Working Group continues to support the strong need for designating a distinct geological epoch, the Anthropocene. Landscape-altering human activities leave behind distinctive evidence (plastics, aluminum, concrete, black carbon, among others) in the sedimentary record. The group has received widespread media attention and recent articles in the New York Times, Los Angeles Times, and Washington Post demonstrate the extent to which interested in topic crosses academic and non-academic boundaries.

On a related topic Tony is the co-author on a research article by Ceballos et al, 2015, on the sixth mass extinction, and it was the #3 most popular academic paper (and shared and read outside and within academia) published in 2015 according to Almetrics.  It was also #15 in the top 100 Science papers listed in Discover Magazine.

 

Assistant director reunites with UCMP alumni in Ethiopia to investigate Mesozoic ecosystems

Assistant director Mark Goodwin is in Ethiopia for several weeks as part of a collaborative project with UCMP alums Greg Wilson (University of Washington) and Randall Irmis (Utah). Together with colleagues from the University of Oklahoma, Addis Ababa University, and Mekelle University in Ethiopia, the team is investigating non-marine Mesozoic ecosystems from the Northwestern Plateau, Ethiopia.

Mark reports "we had great success in the Late Jurassic units and it is gratifying working with Ethiopian students and staff from the Earth Sciences Dept at Addis Ababa University. In the late Jurassic Mugher Mudstone, in addition to turtles, fish, croc teeth and verts, we found a partial crocodile skull with brain case and parietals, partial lower jaw, many allosauroid-like theropod teeth at almost every site and finally some large dinosaur bones - still fragmentary but we're getting there - and very rich micro vertebrate localities that just have to have mammals - collected some bags of sediment from each. Working with the Earth Sciences Dept at Addis Ababa University has been great and hopefully a model for future work and lots of opportunity for collaboration, including informal science."

Bones in the Belltower, a Berkeley Science Review feature by Sara ElShafie

fall_2015_elshafie_featureThe Fall 2015 issue of the Berkeley Science Review features an article by Sara ElShafie, a UCMP graduate student in the Padian Lab, on the McKittrick tar seep fossils that have been stored in the Campanile since the 1930s. The convergence of an Institute of Museum and Library Services grant to the UCMP to clean and catalogue more the 12,000 specimens in the collection and the centennial celebration of the Campanile in 2015 shined a spotlight on these unique fossils.

In interviews with UCMP graduate students Eric Holt and Ashley Poust, and UCMP staff Lisa White and Pat Holroyd, Sara details the work performed to preserve history and scientific significance of the McKittrick collection. Over 3,000 collective hours spent by more than a dozen students will improve the accessibility to the collection for future research and a rich digital archive facilitates sharing with the education community.

The Berkeley Science Review is a graduate student-run magazine showcasing research conducted UC Berkeley in a variety of disciplines.

Making North America, a 3-part NOVA series that originally aired on PBS in November 2015, is a richly illustrated journey through the geological history of the North American continent. UCMP Director of Education and Outreach Lisa White appears in episodes one (Origins) and three (Human) in segments shot in northern California.

Lisa joins paleontologist and Director of the Smithsonian National Museum of Natural History Kirk Johnson, the series host and narrator, along the San Andreas fault in Tomales Bay and in a gold mine near Placerville, CA to explain the unique geological features in California.

Lisa was recently profiled in Berkeley News and talked about her experience filming the series and her commitment to broadening participation in the geosciences.

Humans began altering natural world 6,000 years ago

Scientists have found an abrupt change about 6,000 years ago in how terrestrial plant and animal species coexisted, right about the time human populations were ballooning and agriculture was spreading around the world.

The findings suggest that human activity had reached a tipping point where hunting and farming were impacting the natural world in irreversible ways — changes that have continued to increase to this day.

The researchers, including UC Berkeley’s Cindy Looy, an assistant professor of integrative biology, will report their findings in the Dec. 17 issue of the journal Nature.

The scientists looked at fossil data on how species coexisted over the past 307 million years, specifically how often a particular pair of plant or animal species is found within the same community. Out of all possible combinations of two species in a certain region and time interval, the proportion of pairs of species that co-occurred remained relatively stable until 6,000 years ago. At that time, the chances of co-occurrence dropped significantly, suggesting that humans were creating some barrier to the dispersal of plants or animals.

"This tells us that humans have been having a massive effect on the environment for a very long time," said lead author S. Kathleen Lyons, a paleobiologist in the Evolution of Terrestrial Ecosystems (ETE) program at the Smithsonian Institution's National Museum of Natural History in Washington, D.C.

Analyses of modern communities of plants and animals have found that for most pairs of species, the presence of one species within a community does not influence whether the other is present or absent. For pairs where there is an association, most occur within the same community less frequently than expected, suggesting some influence keeps them apart.

But when Lyons, Looy and their colleagues investigated the composition of ancient communities using fossil data, they found exactly the opposite. Their analysis showed that from 307 million years ago, the time known as the Carboniferous period, to about 6,000 years ago, in the Holocene epoch, there was a pattern of pairs of species occurring together within communities rather than being segregated.

"The proportion of co-occurring species pairs was relatively stable from the late Paleozoic until 6,000 years ago, even during periods of major climate change and mass extinction and despite the appearance of many new players in the terrestrial ecosystems, such as mammals and flowering plants," Looy said. "The decline of coupled species pairs in the Holocene also cannot be explained by the transition from the last glacial to the current interglacial at the end of the Pleistocene, as this happened too early. Instead, it is more likely caused by an increase in human population size and the resulting land use and agriculture."

Around the time co-occurrence patterns changed, humans were becoming increasingly dependent on agriculture, a cultural shift that physically altered the environment and would have introduced artificial barriers to dispersal never seen before. Even at low levels of agriculture and other human impacts, there was a detectable shift in co-occurrence structure, indicating that species were not able to migrate as easily as they did for the previous 300 million years.

Sharing the Collections at UCMP

The new year's calendar focuses on the collections and the unique specimens that can be found here. UCMP is a research museum, which means that access is limited to researchers, our students, and affiliates. The 2016 calendar allows us to bring the collections to our supporters and the general public.

Grants from the National Science Foundation and the Institute of Museum and Library Sciences enabled us to restore, catalog and digitize new specimens more rapidly than ever before. The result was an increase in integration and accessibility of the collections for both research and educational purposes.

What’s inside the calendar?

The calendar showcases our fossils, diversity and volume of our collections, as well as the exciting activity happening inside the museum.

It features spectacular images of specimens representing each of our four collections supplemented with fun facts, such as the age of the fossils and where they were found! It also shows different ways of visualizing fossils. Apart from photographs, there are scanning electron micrographs of the microfossils and 3-D volume renderings of a pachycephalosaur dome fossil.
