    :cool:In the sci-fi"Pride and Prometheus",there is a sentence:Beneath the glass was a collection of bones that had been unearthed in the local lead mines. The card lettered beside them read: Bones, resembling those of a fish, made of limestone.
    here,the word "limestone"means it is the original bones of the fish,or moden people copy the fish's bones with some stone?

    Permineralization is one of the ways in which a plant or animal can be turned into a fossil. During the process of permineralization, mineral rich water seeps into the void spaces of an organism, leaving deposits of minerals behind which slowly build up, creating a cast of the organism.

    I am one of those antiquated fossils that thinks there should be science in SCIENCE fiction.

    And whose fault is that? I merely provided a link that explained the phenomenon he asked about. I am not going to get that book and read some of it to figure out what it has to do with the story.

    It just means that nature and time replaced the bones with limestone.

    Me too. I know next to nothing about geology but my bullshit science detector just went Whoop! Whoop! Would fossils bones of even the earliest bony fish (Devonian? 359 million years ago) be found in lead ore bearing rocks which are billions of years old?

    Oh yeah, lead is degenerate uranium ain't it. I guess there shouldn't be any fossils there.

    I didn't notice that.

    Actually, look up Cromford Moor Mine/Black Rock in Derbyshire (haven't worked out how to include links yet). Lots of lead mining in limestone deposits with fossils dated to 340 million years ago. Apparently the lead is deposited via mineralisation (only the vaguest idea how this works).
