Scaring Children with Teeth
The teeth of Helicoprion can be somewhat frightening in a number of different ways. However, we should probably make sure that the kids in the audience are not frightened when they look at sites like Prehistoric Wildlife that showcase the teeth and the many different hypothesized alignments of those teeth over time. The number of alignments and positions of the teeth are actually somewhat amazing, all things considered; every idea that was put forth had those teeth in some interesting and new position in the body of the shark until their actual position was surmised in the last 50 years or so. In addition to the history of the teeth on Prehistoric Wildlife, there are a number of short informational videos and clips of longer documentaries from Discovery and Animal Planet that are worth checking out. This shorter clip from Discovery Canada goes well with the comprehensive fact page and leave us some other quality videos for tomorrow.
