Harrytoombsia
The placoderm genus Harrytoombsia was a fast-swimming predator.
It had knife-like blades, covered with tissue similar to enamel, on the outer edge of the jaw.
Harrytoombsia was the ‘little brother’ of the five-metre-long placoderm Dunkleosteus, the giant shark-like fish of its time, which preyed on its smaller relatives.
