Congratulations to Selina Robson and Kendra Walters who were nominated for membership into Phi Beta Kappa, the oldest and most prestigious honorary society in the nation! Additionally, Kendra was designated as one of the Oregon Six, denoting her as one of the top six outstanding students of the 2016 graduating class at UO.
Another Thesis Presentation!
Congratulations to Kendra Walters who gave a wonderful presentation of her Senior Thesis yesterday. Her research focused on testing the Species-Energy hypothesis for mammals in the United States over the last century. Kendra will be heading off to UC Irvine this fall to start a PhD studying Microbiology.
Senior thesis presentation!
Congratulations to Danielle Oberg who successfully presented her senior research project today! She worked on the insectivores from Cave Basin, a new site in central Oregon. Good Work Danielle! Danielle will be headed off to East Tennessee State University to work on her masters this fall.
Paper published on 50 million years of rhino arthritis
Lab alumna Kelsey Stilson and PI’s Drs. Hopkins and Davis published a paper today discussing the evolution of arthritis in rhinos in the open-access journal PLoS ONE. They found that with increased mass, adaptation to running, and increased life span, there is an increase in arthritis in the limb bones of rhinos. Congratulations on your paper!
Figure 1: Time-calibrated phylogeny of rhinocerotid taxa used in this study with outgroup H. eximius. The thicker bars indicate the actual first and last appearance data (FAD and LAD) of the fossil localities included, not the comprehensive range of the species. D. bicornis has no blue line because only modern bones were examined. Tree was pruned from Cerdeño’s 1998 morphologic phylogeny or Rhinocerotidae and time-calibrated in RStudio using the ‘equal’ setting in the function timePaleoPhy() in the software package ‘Paleotree’. Tree was set to be fully dichotomous and to extend all the way to the LAD.
New Species of Agriochoerid Named!
A new paper online early today in the Journal of Vertebrate Paleontology, written by grad student Meaghan Emery and PI’s Drs. Davis and Hopkins, named a new species of agriochoerid (clawed-oreodont) from the Hancock Mammal Quarry in eastern Oregon! They not only name the new species, but they also discuss variation and all of the reason why this is a new and different species. Check it out here. Congratulations on your good work!

Fall Meetings
It has been a busy fall for the UO Paleontology lab. We had 5 poster and 3 oral presentations at the Society of Vertebrate Paleontology and Dr. Hopkins gave an oral presentation at the Geological Society of America meetings. Win McLaughlin also has a poster presentation on her work in Kyrgyzstan at the American Geophysical Union meeting this week. There will also be 3 poster and 1 oral presentations at the January 2016 Society for Integrative and Comparative Biology meeting in Portland, Oregon. Go us!
Two New Grants
Congratulations to Dr. Davis who has brought two grants to the University of Oregon. The first one is a NSF Advancing Digitization of Biodiversity Collections grant for digitizing invertebrate fossils from the Cenozoic of the eastern Pacific and was awarded to several institutions, headed by the University of California Museum of Paleontology. The second is an EarthCube Grant awarded to the Neotoma Database for migrating data from other databases (e.g., MioMap) to Neotoma.
Back From the Field!
Drs. Hopkins and Davis, Nick, Kendra, and Danielle just returned from a successful two weeks of field work in Eastern Oregon! Liz White (our good friend and exhibit designer from the Museum) and Dr. Stephen Frost (Anthropology) joined for a couple of days as well. They explored the Crooked River area, John Day Basin, and localities near Madras, and brought back many new specimens to add to the Museum collections! Nick and a small field crew will be back out to the John Day Basin later this summer.
Two Presidential Undergraduate Research Scholars in the vert paleo group
Congratulations to Selina and Kendra on being part of the first cohort of Presidential Undergraduate Research Scholars! They’ll be supported by the program in pursuing their thesis projects next year. You can read more about it here.
New Paper Published!
Grad student Nick Famoso and PI’s Edward Davis and Samantha Hopkins had a paper published online early today! The paper, titled “Are Hypsodonty and Occlusal Enamel Complexity Evolutionarily Correlated in Ungulates?,” was published in the Journal of Mammalian Evolution. You may find a copy of the paper here. Congratulations to them and their two additional co-authors!
