His goal is to try to understand the processes and mechanisms of
organic microfossil preservation and to reconstruct the biology, and environmental conditions and perturbations of the Neoproterozoic.
Marshall and his colleagues proved the concept of testing for vanadium on known microfossils with acknowledged biological origins on Earth —
organic microfossils called acritarchs that might not be far from the kinds of traces of life possibly existing on the Red Planet.

Twisted stalks were then observed using microscopic and spectroscopic techniques, 1) to determine whether structures are preserved and 2) to characterize their mineral and
organic composition and 3) to provide spectroscopic signatures that could be useful for
microfossil search in the rock record.
They include mostly single - celled
microfossils ranging from a few micrometres (one - millionth of a metre) to one millimetre in size, and each is made up of a sac of
organic tissue (vesicle).
«Throughout the world, latest Permian records of
organic - walled
microfossils are characterized by the common presence of remains of filamentous organisms, usually referred to the palynomorph genus Reduviasporonites.»
