Color vision and camera eye
editThe Financial Times reported in 2016 from London's Natural History Museum that, "We don’t know whether trilobites saw in colour [apparently yes] but some fossils of very early fish certainly show evidence of doing so. The oldest is a fish called Cheiracanthus that lived 388 million years ago. Its eyes are preserved well enough to retain signs of the rod and cone cells that exist in the retina of all modern vertebrates with colour vision. These ancient fish already have the same “camera eye” structure..." source: https://www.ft.com/content/ca718ed4-4303-11e6-9b66-0712b3873ae1 Perhaps an editor with more knowledge than I have on this could consider updating the main article with a section on this. Such early vision is an astounding paleontological discovery and I'm sure of great interest to everyone curious about the fossil record!
