A jaw-dropping conundrum: Why do mammals have a stiff lower jaw?
From the 20-foot-long jawbones of the filter-feeding blue whale to the short, but bone-crushing, jaws of the hyena and the delicate chin bones of a human, the pair of lower jawbones characteristic of mammals have evolved with amazing variation. But at first glance, having a single bone on each side of the head — which creates a stiff lower jaw, or mandible — doesn’t appear to give mammals an advantage over other vertebrates, which have at least two and as many as 11 bones comprising each side … [Read more...] about A jaw-dropping conundrum: Why do mammals have a stiff lower jaw?
Life cycles: bringing new questions to old collections
Frankfurt, Germany is a museum town. Along the south side of the aptly named Main River are museums of Renaissance art, iconography, sculpture, design, and film. Each of the old waterfront mansions is home to treasures that spill out through their gardens and into the street, where today’s working artists sell pieces of equal beauty in the public market. It seems required that every footbridge across the river has a café and an accordion player at either end. North of the river is modern art, … [Read more...] about Life cycles: bringing new questions to old collections

Forty phyla in forty days
Marine invertebrate zoology in Friday Harbor, Washington Paleontologists speak of Friday Harbor Labs in the nostalgic tones reserved for only the best field stations. As I hopped off my ferry to the San Juan Islands, carried my duffel bag through the namesake harbor town, and stepped at last under the campus’ old-growth cedars, it was clear why. I came to take FHL’s flagship summer course, Marine Invertebrate Zoology, which surveys forty phyla in as many days. In the mornings, we … [Read more...] about Forty phyla in forty days
Antarctica yields oldest fossils of giant birds with 21-foot wingspans
Fossils recovered from Antarctica in the 1980s represent the oldest giant members of an extinct group of birds that patrolled the southern oceans with wingspans of up to 21 feet that would dwarf the 11½-foot wingspan of today’s largest bird, the wandering albatross. Called pelagornithids, the birds filled a niche much like that of today’s albatrosses and traveled widely over Earth’s oceans for at least 60 million years. Though a much smaller pelagornithid fossil dates from 62 million years … [Read more...] about Antarctica yields oldest fossils of giant birds with 21-foot wingspans
Best laid plans: a new fossil of a dinosaur mother full of eggs and information
Birds and bird eggs are familiar stuff: we see them daily in our backyards and even in our kitchens. But ask the classic questions: where did egg laying come from and how did it get that way? Answers are hard to come by. A gravid theropod dinosaur discovered with fossilized eggs still inside it helps explain how birds evolved their distinctive ways of reproducing. Described in a paper in the Journal of Vertebrate Paleontology by recent UCMP alumnus Ashley Poust and co-authors from China and … [Read more...] about Best laid plans: a new fossil of a dinosaur mother full of eggs and information
The tortoise and the hare: the varied pace of research
Confinement at home due to the Covid-19 pandemic has provided an opportunity to reflect on the pace of my research over the last year. Thinking back to Aesop’s fable of the Tortoise and the Hare, I see that my research has adopted traits from both animals: sometimes moving slow and steady, while other times travelling at break-neck speed. Despite this variability in research pace, the UCMP has been a constant presence during my research through its supportive staff and generous financial … [Read more...] about The tortoise and the hare: the varied pace of research

Fossil fishing for clues about a prehistoric invasion
The school year has ended, but with the ongoing pandemic pushing most usual summertime activities off the table, my thoughts have been turning to how I spent my last summer: organizing fishing trips to Nevada. These excursions weren’t exactly spent relaxing on a boat in Tahoe reeling in trout. Rather, my companions and I were kneeling in a defunct quarry under the desert sun, prying apart layers of blindingly white rock in search of the fossils of small fish that once lived in a long-disappeared … [Read more...] about Fossil fishing for clues about a prehistoric invasion

Reading Between the Rocks: The Return to Anticosti
Having the opportunity to return to a field site is, in many ways, like rewatching a favorite movie series. On your first pass through, everything is unexpected and unfamiliar. For some movies, the amount of information and detail can be overwhelming. On your second pass through, even though you now know the characters, the setting, and the plot, you begin to notice important details that you missed the first time. Each time you rewatch the series, you discover new things and form new ideas, and … [Read more...] about Reading Between the Rocks: The Return to Anticosti
Paleontologic Data Fossilized on IBM 8” Floppies
The Pennsylvanian (323-299 million years ago) is one of the most interesting time periods in Earth’s history. Giant dragonfly relatives like Meganeura (>2 ft wingspan!), 8-ft-long millipedes named Arthropleura, and early mammal-like reptiles lived in a world that likely had atmospheric oxygen levels well above today’s. These animals roamed a landscape dominated by extensive peat swamps, covering large parts of what was then Euramerica. These swamp forests would look entirely … [Read more...] about Paleontologic Data Fossilized on IBM 8” Floppies

Researchers from Down Under come to UCMP to study our Australian fossils
Kangaroos … in Berkeley? That’s right, mate. You won’t find them leaping around the campus, though. Because they’re in the Museum of Paleontology’s fossil collections. In the 1950s, then-curator and professor Ruben A. Stirton decided to go to Australia’s Tirari Desert to look for fossil marsupials. He wanted to find evidence to answer the question of the origin and spread of marsupials through space and time. Did they come from Australia, Antarctica, or … [Read more...] about Researchers from Down Under come to UCMP to study our Australian fossils

Reading between the rocks: Reinterpreting the Late Ordovician mass extinction
This past summer, I had the opportunity to conduct my first field season on Anticosti Island (Québec, Canada). Located in the subarctic of Canada, Anticosti Island preserves a 200 kilometer-long transect of ancient seafloor. Late Ordovician tropical reefs and fossils are beautifully preserved across the island in towering coastal cliffs and river canyons. The sheer size of the island is astounding, and the insight its fossil record could provide into early Paleozoic marine communities is … [Read more...] about Reading between the rocks: Reinterpreting the Late Ordovician mass extinction
How often does extreme competition occur between species on the ocean floor?
Look around in nature or even in the city and you will see that organisms are not static entities, but interact with one another. Think of a robin with a worm in its beak, a tick crawling on your leg looking for a spot to puncture your skin, or two bucks fighting during the rutting season for the right to mate. The sea floor is also a place where animals search or fight for food to stay alive. On the continents, food is not unlimited; every individual tries to collect a piece of the pie (Fig. … [Read more...] about How often does extreme competition occur between species on the ocean floor?
Russell Waines’ stromatoporoid collection
Russell H. Waines was a geologist who dedicated most of his life to ancient sponges, the stromatoporoids, which were one of the most important reef builders during the Paleozoic. When I was a graduate student researcher at the UCMP in 2013, I had the pleasure of organizing this collection (Figure 1), which includes approximately 2000 fossil specimens (566 of which are registered in the UCMP database) mainly from the Devonian of Nevada, but also from Alaska, Arizona, California, New York, Utah, … [Read more...] about Russell Waines’ stromatoporoid collection

A new destination for disaster enthusiasts
The Cretaceous-Paleogene (K-Pg or K-T) mass extinction — the event in which the non-avian dinosaurs, along with about 70% of all species in the fossil record went extinct — was probably caused by the Chicxulub meteor impact in Yucatán, México. However, scientists have long wondered about the massive volcanic eruptions that were occurring in northwestern India at about the same time, the Deccan Traps. Volcanism is the likely cause of several prior mass extinctions, with no convincing evidence for … [Read more...] about A new destination for disaster enthusiasts
A Pleistocene pit-stop: the Barnosky lab excavates Natural Trap Cave, Wyoming
You might think that an 85-foot-deep hole where a bunch of horses, wolves, camels, elephants, and plenty of other animals accidentally plummeted to their death over tens of thousands of years would have enough red flags to make going into it yourself sound like a bad idea. But what if these unfortunate critters could tell you what their life was like and how they died? What if they could give you a warning about their death in a warming world after the last ice age and what it means for life in … [Read more...] about A Pleistocene pit-stop: the Barnosky lab excavates Natural Trap Cave, Wyoming
What do traces of predators tell about ancient marine ecosystems?
Reconstructing biotic interactions is crucial to understand the functioning and evolution of ecosystems through time, but this is notoriously difficult. Competition in deep time cannot be readily seen except for overgrowth of one organism by another under the assumption that both were alive at the same time. Parasites usually do not preserve because they are soft-bodied and tend to be small so that they are not spotted easily. The most abundant evidence of biotic interactions comes from the … [Read more...] about What do traces of predators tell about ancient marine ecosystems?
Understanding the evolutionary history of the cassiduloid echinoids
It is widely recognized that major groups evolve at different rates, in their own evolutionary trajectories. Some evolve fast and are very diversified while others evolve slowly and may never experience an explosion of diversity throughout their trajectory. One of my research interests is understanding the pace of morphological evolution through time, and the organisms selected to investigate this topic are the irregular echinoids. Commonly known irregular echinoids include the sand dollars … [Read more...] about Understanding the evolutionary history of the cassiduloid echinoids

A Hitchhiker’s Guide to the Pleistocene Sea
Using Fossil Whale Barnacles to Reconstruct Prehistoric Whale Migrations Baleen whales, as we know them today, lead lives that are largely defined by their annual migrations. Every year, whales spend their winters breeding and reproducing in tropical waters, then travel to poleward feeding areas each summer. For North Pacific humpback whales, winter breeding areas cluster around Central America and Hawaii, and then they travel to the Gulf of Alaska to feed in the summer (small numbers also … [Read more...] about A Hitchhiker’s Guide to the Pleistocene Sea

Cryptic caves and paleoecology of crustaceans in Cenozoic coral reefs
Just some months ago on a Saturday in July, I had the pleasure of snorkeling above the only coral reefs in the continental Unites States. These reefs in southern Florida still harbor many species of corals, fish, and other animals including crustaceans such as crabs, shrimps, and lobsters. These decapods are difficult to spot while snorkeling, but that does not mean they are not there. Their usually small size in this landscape of incredibly variable topography ensure they are able to hide … [Read more...] about Cryptic caves and paleoecology of crustaceans in Cenozoic coral reefs
Terraces through time: Reconstructing fossil beaches in southern California
San Nicolas Island is a strange, far-away place very familiar to a surprising number of Californians.

New research shows how mammals became smaller in response to dramatic climate warming
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 … [Read more...] about New research shows how mammals became smaller in response to dramatic climate warming

Mighty microbes implicated in Permian mass extinction
Ninety-six percent of marine and 70% of terrestrial species died in the Permian mass extinction, which began about 252 million years ago and lasted for over 20,000 years. Geochemistry tells us that this extinction coincided with a severe and rapid change in the Earth’s carbon cycle, but this alone could not have been the cause of the extinction. Initially it was thought that carbon dioxide released by Siberian volcanism explained this change in the carbon cycle but the volcanic outgassing was … [Read more...] about Mighty microbes implicated in Permian mass extinction
