The roottooth fish lived during the Carboniferous period, 330 to 300 million years ago.
The root tooth fish, the model species name Hitch's root tooth fish, is huge, the largest individual is more than 7 meters long and weighs more than 2 tons. The body rolled round like a torpedo, covered with hard scales.
In Scotland, fossilized teeth have been found, some of which are even more than 20 centimeters long.
Scientists determined that the teeth belonged to a prehistoric fish, so he named rhizodus, which means "root-like teeth", and the pattern species was rhizodus hibberti.
