Here is a gold coated foraminifera fossil. It was prepared to be imaged under a scanning electron microscope (SEM). I believe it was prepared back in 2008. It reminds me of a Peneroplis planatus similar to the one found at foraminifera.eu
These gold coated fossils remind me of the James Bond film Goldfinger (1964) where Goldfinger has the person killed by covering her in gold paint.
Thanks to Michael Hesemann at www.foraminifera.eu for the samples and they are very nice to look at.
