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.[2]References1. ^{{cite web|url=http://fossilworks.org/bridge.pl?a=taxonInfo&taxon_no=34345|title=Fossilworks: Harrytoombsia|website=fossilworks.org}} {{Placoderm-stub}}2. ^{{cite web|url=http://utstallning.nrm.se/fossilochevolution/en/devon/animals/devon1hav/vilketdjur/visarvilketdjur1.4.4f4d16d8151338bf60331de9.html?dinoid=4.4f4d16d8151338bf60331d52|title=Visar vilket djur 1 - NyaUtställningar|website=utstallning.nrm.se}} 2 : Fossil taxa described in 1979|Extinct animals |
