I am glad to announce that I am starting a two years post.doc at the University of Iowa founded by the @snsf_ch. I joined Jonathan Adrain's lab to continue my studies in trilobites, in particular the Lower Ordovician faunas from North America. 🪳🦞🦀🦂

Happy to announce that our project "The past as a key to the present: A unique ‘reverse actualistic’ approach to synchrotron imaged snapshots of Early Palaeozoic life and death" that we prepared with Valéria Vaškaninová got funding from the Czech Science Foundation 🥳

From a Pompeii-like ash burial in Morocco, a new study presents 3D trilobite fossils with a remarkably well-preserved anatomy. The results point to marine volcanic ash deposits as important sites of exceptional fossil preservation.

Meet Setapedites abundantis, a 485 million years old arthropod described by @LorenzoLustri, @PGueriau and @cambriancritter. This tiny animal is abundant (hence it's name) in some levels of the Fezouata Shale and is a distant relative of today's 🕷️🦂

New trilobite work 🦂🦀🦞🪳! Here, we present a new odontopleurine trilobite from the Middle Ordovician of Death Valley. As well, the classification of Ordovician odontopleurines is review. Really beautiful material!

🚨🚨 Paper alert! I am happy to share my new paper with @PGueriau and @cambriancritter 🥳. The paper talks about the suspension-feeding radiodonts from the Fezouata Shale 🇲🇦. Spoiler: Aegirocassis was not alone. Check out the link if you want more details

Earlier this week @GaetanPtn and I published a review about Anomalocaris and other radiodonts. Over 130 years of research on these bizarre creatures has revealed their importance for Paleozoic ecology and arthropod evolution. It’s been a wild ride! Enjoy! bit.ly/3NO6ykW

Ah yes, I was also curating Tariccoia (Liwiidae, Nektaspida) in the same drawer. That explains the unusual systematic treatment of Tremaglaspis!

Včera jsem na @Akademie_ved_CR vysvětloval, co jsme objevili v našem novém článku s @tapho_zoan a @PerezPeris1. Spoiler alert: je to o larvách trilobitů =(:[[[[} 😉

Mláďata trilobitů v prvohorách sehrála zásadní roli jako potrava pro některé mořské živočichy. Některá přestala žít na dně a začala se volně vznášet. Hlavním autorem studie z mezinárodního výzkumu je @lukas_laibl z Geologického ústavu AV ČR.
