My brother Greg Wilson is a vertebrate paleontologist at the University of Washington. Growing up together, we thought more about playing in the World Cup or World Series than about collecting fossil vertebrates – but we have more opportunities to interact as a paleontological team nowadays. Greg’s research focuses on quantifying shape changes in mammalian dentitions across the Cretaceous-Tertiary boundary. He leads field work in Montana, Baja California, and India. The photograph above shows us in front of El Gallo Formation sediments after a day’s field work in Baja in September 2007.

Dhananjay Mohabey is a geologist at the Geological Survey of India (Nagpur). He and I are working on new fossil reptiles from central and western India. He is pictured at the Sanajeh indicus locality in Dholi Dungri,  Gujarat.

Paul Sereno (right), was my PhD advisor at the University of Chicago. He developed TaxonSearch, which is an online resource for phylogenetic definitions of taxa. Paul and I have worked together on many projects, and we are currently working on a description of the bizarre sauropod Nigersaurus taqueti. French paleontologist Didier Dutheil (left) is a fossil fish expert at the Muséum national d’Histoire Naturelle in Paris. Didier is also a documentary film maker and champion de monde de mikado. Hans Larsson (center back) was a graduate student with me at the University of Chicago. He is Curator of Fossil Vertebrates at the Redpath Museum and Associate Professor of Biology at McGill University. Hans’ research focuses on the ontogeny and phylogeny of archosaurs. Paul, Didier, and Hans are shown here somewhere between Bolivia and Brazil during a wild motorboat ride in 1996.

Shanan Peters studies macrostratigraphy and macroevolution at the University of Wisconsin and manages the excellent interactive Sepkoski online genus database. We have been working together in the Lameta Formation of India.

Kristi Curry Rogers is a dinosaur expert and paleohistologist at Macalester College. She and I co-edited The Sauropods: Evolution & Paleobiology, and we are currently working on a project focused on the phylogeny of titanosaur sauropods. Kristi is shown here in the field in Montana with her infant daughter Lucy.

My ‘bonus sister’ Caroline Strömberg is a paleobotanist at the University of Washington. She studies the evolution of grasslands. She and colleagues recently described the first bona fide fossil grass phytoliths from the Cretaceous, found in coprolites from India.

Brigham Young University paleontologist Brooks Britt (right), National Parks Service paleontologist Dan Chure (center), and I have been working on sauropod dinosaurs from the Early Cretaceous of western North America. Here we are pictured with the holotypic skull of Abydosaurus mcintoshi.

Iyad Zalmout is postdoctoral researcher at the Museum of Paleontology. He studies the evolution of Eocene sea cows and vertebrate paleontology of the Arabian Peninsula. We are working on Cretaceous vertebrates of Saudi Arabia Jordan.

Roger Smith is the Curator of Karoo Palaeontology at the Iziko South African Museum. He has a broad range of research interests that include sedimentology and stratigraphy of the Karoo Basin, fossil footprints, and therapsids. We work together on fossil footprints from southern Africa. He is shown in Blikana, South Africa with a partial ilium of a sauropodomorph.

Claudia Marsicano is a vertebrate paleontologist at the Universidad de Buenos Aires, Argentina. Although her primary interest is in the phylogeny and evolution of temnospondyls, she is also interested in fossil footprints. She is pictured here in Namibia, where she was studying some interesting Early Permian sequences that contain temnospondyl bones.

Hussam Zaher studies the evolution of snakes and other reptiles at Universidade de São Paulo in Brazil. He and I are working together on a description of the titanosaur Tapuiasaurus macedoi from the Early Cretaceous of Brazil.

Ronan Allain is a dinosaur specialist at the Museum National d’Histoire Naturelle in Paris. Ronan is pictured here holding a vertebra of the new theropod Berberosaurus, which he recently described in JVP.
