🚨Paper alert🚨 Permian bacteria fossilized as rod-shaped pyrite aggregates! A sweet taphonomy-oriented project led by L. Melim. If pyrite aggregates can similarly form in spherical bacteria, how could we distinguish them from extracellularly formed framboids 🤔🤔🤔

#FossilFriday Elrathia kingi is one of the most common trilobites in the Cambrian rocks of Utah’s West Desert. Thousands are found yearly—many geologists have one on their fridge. Yet this specimen - first published in 2008 - is the only one I know of that preserves both limbs and gut remains. 🤩

Another 🚨Paper alert🚨 Everything you ever wanted to know about colony development in graptolithine pterobranchs 🪸 Still much to uncover, but this sums up what we know so far. Enjoy, it is open access 😜

For anyone interested in our work on Utah’s mid-Cambrian Marjum Formation and its extraordinary fossil biota, here’s a short article detailing the project’s genesis and significance. Many thanks to the Museum of Comparative Zoology at Harvard for highlighting this research in their annual report.
