Homodont Found!

Angus was intrigued by part of a skeleton that he found in his garden. No-one seemed to know what it was apart from being part of a jaw. There were no molars or incisors but the teeth resembled human teeth! Behind were another set of teeth starting to grow, which was even more fascinating.

Angus brought the skeleton into school and with the help of Mr Clarke, our caretaker, and Plymouth Museum and University it was identified as a homodont (all teeth the same) and a non-mammalian vertebrate. The only UK homodonts are dolphins! However look closely and you will see it is too small for a dolphin.

Both the University and Museum believe it to be the upper jaw of a WRASSE or BALLAN and although the sea is not far away how did it come on to land?


Here are some options but perhaps you could think of others?

1. It was caught by a fisherman and later eaten.

2. A storm could have swept it in to the garden.

3. A bird dropped it as it went over land.

4. A cat or a rat dug it up and moved it about.


What an exciting find and to get such help! Perhaps this will start off a new collection for Angus and a trend of pupils researching with the help of local experts?
