In Depth
Belantsea would essentially have been the Carboniferous equivalent of a parrotfish. The body was bulky with strong muscular fins, and an underdeveloped tail which all indicate a preference for manoeuvrability over speed. The teeth are triangular and tightly packed to form a dental arrangement similar to a beak which would have easily broken hard exteriors of invertebrates and bryozoans. Altogether, these features suggest that Belantsea was a reef fish that manoeuvred over prey that could not escape by speed, while also possibly hiding amongst rocks to protect itself from other larger predatory fish, including early sharks.
