It would be truly shocking of macro-scale fossils visible to the naked eye were found (although perhaps fossils of large microbial mattes or films could be found that way?) I suspect fossil hunting on Mars would require a microscope, though I would expect there to be a lot of more mundane geology work a geologist with a hammer could get done quickly.
