The 20-member team was assembled to identify possible human remains at the Barker Ranch in Death Valley after a cadaver dog picked up the apparent scent of a body in February, the Los Angeles Times reported Wednesday.
Using sensitive high-tech devices, the researchers have detected chemical compounds like the kind emitted by decaying bone and tissue, the Times said.
One of the team members is Arpad Vass, a scientist from the University of Tennessee who specializes in the study of the decay of human remains.
"I think there is something decomposed there," Vass told the Times. "But I don't know if an animal died here, or a Native American or a dinosaur way back when."
Team members said they planned to continue working through Thursday.
