A team of researchers have used a combination of analytical techniques (including secondary ion MS and Raman spectroscopy) to characterize a 635 million-year-old microfossil – the oldest terrestrial fossil ever found (1). The image above shows the filamentous structure of the fossil, which has led the team to conclude that a fungus is the most likely origin. This finding could be crucial in helping scientists better understand the timeline of our planet’s terrestrialization – the emergence of organisms from the sea onto land.

By the time I finished my degree in Microbiology I had come to one conclusion – I did not want to work in a lab. Instead, I decided to move to the south of Spain to teach English. After two brilliant years, I realized that I missed science, and what I really enjoyed was communicating scientific ideas – whether that be to four-year-olds or mature professionals. On returning to England I landed a role in science writing and found it combined my passions perfectly. Now at Texere, I get to hone these skills every day by writing about the latest research in an exciting, creative way.
