Abstract Scope	Deciphering the earliest records of life on Earth is a challenging undertaking, especially after billions of years of geological processing that obliterate original biological compounds and that can also generate biology-like structures. We explored ptychographic X-ray computed tomography (PXCT) to reveal in 3D the morphological and mineralogical components of ancient microfossils at the nanoscale. This unprecedented non-destructive investigation revealed ultracellular features with relevance for the unequivocal identification of controversial structures, while the quantitative electron density information identified organic and mineral components that shed light into the preservation processes. We will present how PXCT can contribute to the understanding of the earliest fossilized traces of life on Earth, and also for the investigation of near-future samples returned from Mars. We will also provide an overview of the latest developments of Sirius, the new Brazilian 4th generation synchrotron that will take advantage of a high coherent flux for different high-resolution imaging methods.
