Robyn Henderek ’15 (Titusville, N.J.) and Wesley Von Dassow ’14 spent their summer vacation waist deep in Panamanian rivers, armed with rock hammers and magnetic compasses.
As interns with the Smithsonian Tropical Research Center in Panama City, Henderek, a double major in geology and anthropology & sociology, and Von Dassow, a geology graduate, were responsible for collecting fossils unearthed by the Panama Canal Expansion Project.
Henderek, Von Dassow, and their Smithsonian colleagues analyzed bedrock representing Panama before, during, and after the joining of North and South America 3-4 million years ago. They sought evidence in fossils as to whether the migration of flora and fauna across the land bridge of the continents affected their biodiversity.
According to Henderek, who is also a member of the swimming and diving team, they found an average of about a dozen fossils per day, ranging from turtle shells to the teeth of the extinct ancestors of rhinos, camels, and horses. After retrieving a fossil, Von Dassow and Henderek returned to their base camp, where they catalogued the item in the Smithsonian database, meticulously cleaned the structure, and then shipped the fossil to the Florida Museum of Natural History, the Smithsonian’s partner organization on the project.
The two Leopards also spent nearly a month in the tropical rainforest of the Azuero Peninsula, working alongside students from the Universidad de los Andes in Bogota, Colombia. They helped to create a geologic map of the peninsula, collect core samples for Paleomagnetic analysis, and catalogue more fossils. The rarest of their finds was a seven-inch tooth of a Megalodon, the prehistoric ancestor of the Great White Shark.
The pioneering fieldwork solidified Henderek and Von Dassow’s desire to pursue graduate degrees in geology.
“We are getting to know how to conduct our own research in the field with very few tools,” Henderek says. “We are seeing real science done in the field.”
