Science Snapshot 10: Elephant Teeth Again

For the next few weeks, along with some of our usual posts, we're posting a series of  'Science Snapshots'.
Science Snapshot was really popular when we ran it last year for Science Week and this will be a continuation along the same theme - that's why this is number nine already!

You can see all of the snapshots so far by clicking here.

Some months ago, I asked you to identify a mystery object from the UCC Zoology Museum. Turns out, it was an elephant tooth! Well, here's one in situ in an elephant skull at the Irish Natural History Museum. Makes more sense when you see where it's supposed to be. Doesn't it?

Mystery Science - Can you tell what it is yet?

Thanks to everybody who tweeted their guesses as to what the mystery item was. Unfortunately nobody got it right - better luck next time!

In fact, it was not a whole animal but just a 'small' part of one of the largest animals on earth. It was.... an elephant molar tooth. From an Indian elephant to be exact.

The pointy bits towards the top are the 'root' part of the tooth which would have been embedded in the gum of the animal. The specimen is resting on the rough grinding surface of the tooth.

If you compare it to the image of the molars in situ, you can see what it looks like from the underneath. An Indian elephant will produce six sets of molars in it's lifetime, although just one pair will be in use at any one time. Once that pair has been worn down, it is replaced with a new pair which push forward from the back of the mouth.
