HOW BIG IT WAS

Acanthostega relative size depiction as described below
Acanthostega was about 50–55 cm long.

Acanthostega was one of the first tetrapods. It had legs rather than fins, ending in fingers and toes, but was still an aquatic animal that could not walk on land. Acanthostega probably lived in shallow, plant-choked swamps, ambushing prey near the water's edge.

An early tetrapod similar to Acanthostega waded through shallow water over 360 million years ago, leaving fossilised footprints with clear toe impressions. This trackway was discovered near the Genoa River in eastern Victoria.
