Apart from it being unusual to have evidence of soft parts, what I find interesting are the increasingly high tech. ways there are of looking at fossils.


The placoderm fossils were analysed using computer X-ray tomography at ANU, a scanning technique that creates a three-dimensional image of complex organic structures. “What this research shows is that 400 million years ago there was already a complex eye, and one that was an intermediate form between jawless and jawed vertebrates,” Dr Young says. “This means that we’re able to add one more piece to the puzzle of how the human eye came to be.”
