A fossilised fish tooth found in the Possil lower black band at Keppoch in Possilpark.
These kind of fish teeth are known as Rhizodus. They come from certain types of lobe-finned fish (rhizodontiforms) which existed from the upper Devonian Period to the upper Carboniferous Period (around 377 to 310 million years ago). Rhizodonts were large fish and some grew to a length of 6 or 7 metres and had teeth up to 22 centimetres long. These long pointed teeth were ideal for hunting prey in the freshwater rivers and lakes where the rhizodonts lived.
