Today we visited the Paleontology Research Laboratory of the Federal University of Acre (UFAC, Floresta campus) to see a vast collection of fossils found in Amazonia. The "smiling buddy" in the photo is a replica of the jaw of a Purusaurus, the largest alligator on Earth that lived in Acre millions of years ago. Special thanks to Professor Francisco Negri who showed us the collection of the laboratory with great enthusiasm. See you later, alligator!
