“ We humans have a saying that we like to get a leg over, but these placoderms they like to get a leg in.

Dr John Hall, Museum of Victoria
A 375 million-year-old fossilised fish is the oldest evidence of sex using copulation. The placoderms had fin-like sexual organs, fins would eventually evolve into legs of land animals, including us, hence Dr Hall’s comparison.
