The fish was rust coloured and my uncle told me that it had turned into some kind of iron over the years. I could be remembering it wrong. It was a long time ago but it was a perfect little fish. You could even see its scales, gills and eye sockets.

that sounds about right ! minerals seep in and replace the bones and skin, whatever is preserved eventually turns to rock or metal. sometimes the preservation can be incredible. I heard of some Dinosaur fossils found in China which had feathers preserved, thus providing an amazing glimpse into the evolution of Avian Dinosaurs into Birds !

this little duck sized Dino had feathers like a Hummingbird
