Field Photos from Madagascar, Aug.-Sept. 1998

Field Photos from Madagascar, Aug.-Sept. 1998

In 1998, a group of us from the Field Museum in Chicago and the University of California – Santa Barbara left for a one-month expedition to Madagascar. Representatives of these institutions had visited Madagascar previously, primarily to prospect the Isalo II Formation, a group of rocks of Middle to Late Triassic age (225-230 million years […]

Field Photos from Central Chile, March 2002

Field Photos from Central Chile, March 2002

In March of 2002, we planned a short trip to south-central Chile to prospect some exposures near Laguna del Laja that John, Andy, and Reynaldo had visited the previous year. This was my first trip to central Chile (my previous trips were to the northern part of the country), so I was looking forward to […]

Field Photos from Northern Chile, Sept. 2001 and Aug. 2004

Field Photos from Northern Chile, Sept. 2001 and Aug. 2004

In September of 2001 we made a second trip to the northern part of Chile to prospect some new sites and do additional collecting of the early Miocene (Santacrucian) locality of Chucal. We made the trip a little bit later in the year (i.e. not in the middle of austral winter) in the hopes of […]

Tinguiririca

Tinguiririca

Perhaps the most important of our Chilean localities is Tinguiririca, which is located in central Chile near the town of Termas del Flaco. In the transition between the warm, equitable climate of the Eocene Epoch (54.8 to 33.7 million years ago) and the cooler climate of the Oligocene Epoch (33.7 to 23.8 mya), numerous ‘archaic’ […]

Other Central Chilean Localities

Other Central Chilean Localities

Many of the other fossils we have discovered in Chile come from a variety of localities in the central part of the country. All of these sites apparently sample the Abanico Formation, a group of rocks that was deposited mainly between about 40 million and 15 million years ago. This particular formation tends to preserve specimens in great […]

Peru

Peru

I am interested in the extinct mammals of Peru for many of the same reasons I am interested in  the extinct mammals of Bolivia. Therefore, I jumped at the opportunity to collaborate with a French and Peruvian research team led by Pierre-Olivier Antoine on a project searching for mammal fossils in the eastern part of […]

Digging for Fossils

Digging for Fossils

When I tell people I am a paleontologist and that I go out on “digs,” they usually think I spend most of the trip literally digging in one place for fossils. This happens occasionally but is not typical of my fieldwork. Most of my time in the field is spent looking for fossils; relatively little […]
