From the article
Our study looks at the Tl isotope composition of two organic-rich shales deposited during an extinction & the SPICE (Steptoean Positive Carbon Isotope Excursion) in the later Cambrian (~494 million year ago). This event potentially represents a deoxygenation event in the ocean at the time. (5/7) 🧪⚒️
