My Funny Picture

What animal does this tooth belong too??? Pics!?

My daughter found this tooth in her school playground. The tooth is about an inch long with two smaller teeth on the sides that are about a quarter inch. The teeth are attached to a bone that looks really old. The bone really looks more like a rock or a fossil. The teeth are still a bit shiny. Here are the pics! http://i56.photobucket.com/albums/g185/hfa1730/IMG_2989.jpg http://i56.photobucket.com/albums/g185/hfa1730/IMG_2999.jpg http://i56.photobucket.com/albums/g185/hfa1730/IMG_2994.jpg

1. Alligator?
2. Crocadile or alligator
3. It is most likely an incisor from a dog. (also known as a canine tooth). It could possibly come from a pretty large cat.
4. Well I now it isnt a tooth from a dog or a cat- I have seen plenty of those extracted at work! Looks like a shark tooth!
5. This is not a crocodile or alligator tooth or jaw - and it's ridiculous for anyone who knows even anything REMOTELY vague about dentition to suggest such a thing. Even though Crocodiles have thecodont teeth (and this actually looks pleurodont to me), they DON'T (*really*) have heterodont dentition (not that this is, but to me it's blatantly easy to rule out croc/gator at FIRST glance). It's also absolutely not a CAT jaw because cats have a diasthema between their canines and molars. The curvature on the size of the tooth in comparison to the dentary, (or in this case really, the palatoquadrate or mandible/meckel's cartilage), the two smaller "teeth" on either side, and the larger tooth itself would suggest to me that this is a portion of a shark jaw. Exactly what KIND of shark - who knows.. where exactly do you live? Here's a picture of some fossilized shark teeth for you, too: http://img232.imageshack.us/img232/7585/sharkzx2.jpg
