- adj. fossilized by permineralization
Sorry, no etymologies found.
By comparison, if one were to demineralize a typical well-permineralized fossil, there would be nothing left.
If we're talking about an octopus, it's going to be somewhat more difficult but not impossible to find something like a very large beak or possibly egg cases that have been permineralized.
Alternative theories, such as the one proposed by paleontologist Thomas Kaye of the University of Washington in Seattle, suggest that the soft-tissue is permineralized biofilm created by bacteria while digesting and breaking down the original specimen.
