The students in the tomato class found a bone while out walking and brought it to class to try to determine what animal it belonged to. They made various hypotheses, including rat, wild boar, deer, dinosaur, wolf, and small wild boar. After taking photos and measuring the bone, the teacher responded that it was likely the lower jawbone of a carnivore, noting characteristics like sharp canine teeth and a large carnivore molar tooth. She determined it was probably from a fox or dog, but not a wolf, as wolves have not been in the Vacarisses forest for many years. The students were happy to have their question resolved.
