Martin Brasier, English palaeontologist, biologist, and academic (d. 2014)
Martin David Brasier FGS, FLS (12 April 1947 – 16 December 2014) was an English palaeobiologist and astrobiologist known for his conceptual analysis of microfossils and evolution in the Precambrian and Cambrian.

He was Professor of Palaeobiology at the University of Oxford and Emeritus Fellow of St Edmund Hall. His research critically examined the context and character of the early fossil record, making use of field mapping, logging, optical petrography, stable isotope geochemistry, confocal microscopy, NanoSims microprobes, and lasers for high resolution 3D scanning and laser Raman spectroscopy.

Brasier died in a car accident near Burford, Oxfordshire, UK, on 16 December 2014.
