In February 2017 we published the article Rare Meteorites Common in the Ordovician Period in Nature Astronomy. This the first empirical reconstruction of variations in the meteorite flux to Earth in deep time. We show that the meteorites falling on Earth in the Ordovician period one million years before the L-chondrite parent body breakup were very different from todays meteorites. We show that primitive achondrites that are extremely rare in today’s flux were one of the most common types of Ordovician meteorites. The article was accompanied by a News and Views item “Meteorites: A shift in shooting stars” by Francesca DeMeo at the Massachusetts Institute of Technology, US. Our article received much media attention, reaching an altmetric value in the top 99th percentile.
