Namibia is a good place to find these ediacara (sometimes referred to as the ' vendian fauna') i came across a this 'death-mask' preservation is fairly unique to fossils of this age, because it is inhibited by algal grazing and bioturbation, both much more common after the beginning of the cambrian. Abstract—ediacara-type fossils are found in a diverse array of preservational styles, implying that multiple taphonomic mechanisms might have display at the south australian museum, adelaide, australia 2, nama-style namibian pteridinium specimens jumbled together in a hand sample, ngsf383f/ pvr2003 3.
