In this undated photo made available by the Florida Museum of Natural History, shows the lower jaw of Aguascalietia panamaensis, a new species of ancient camel described by University of Florida researchers online in the Journal of Vertebrate Paleontology. The fossil represents one of the oldest mammals from Panama. Scientists at the Florida Museum of Natural History on the University of Florida campus in Gainesville, Fla., are working with the Panama Canal Authority and researchers from the Smithsonian Tropical Research Institute on a National Science Foundation-funded project to recover fossils, including that of the camel, ancient marlins, turtles and horses, during construction to widen and improve the canal.
