Javier Ortega Hernández Rudy Lerosey-Aubril Ah yes, I was also curating Tariccoia (Liwiidae, Nektaspida) in the same drawer. That explains the unusual systematic treatment of Tremaglaspis!

🚨🚨 Very proud to announce that my first paper, in collaboration with Allison Daley is out ! 🥳🥳 If you want to know everything about radiodonts, be sure to check it out ! bit.ly/3NO6ykW ANOM Lab Institut des Sciences de la Terre - UNIL

Earlier this week Gaëtan Potin 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

#PhDAlert! We have a 4-year #PhDposition available in #Siphonophore biosystematics and biogeography at NaturalHistoryMuseum Universitetsmuseet Universitetet i Bergen. RT highly appreciated. Deadline 15th August. More info & how to apply: bit.ly/PhD_Sipho Aino Hosia Luis Martell

🚨🚨 Paper alert! I am happy to share my new paper with Pierre Gueriau and Allison Daley 🥳. 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 bit.ly/47B1W9k

Funeralaspis n. gen.: a new odontopleurine trilobite from the early Middle Ordovician (Dapingian) of Death Valley, eastern California, #USA, and the classification of Ordovician odontopleurines mapress.com/zt/article/vie… #Taxonomy

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! mapress.com/zt/article/vie…

🚨📄 Paper Alert 📄🚨 Our new work "Babies from the Fezouata Biota: Early developmental trilobite stages and their adaptation to high latitudes" is out! If you like =(:[[[} #trilobites, #evolution, #development, or life in the #Ordovician, you should check it out! See 🧵👇 1/5

If you like trilobites you might know about the Ordovician Walcott-Rust Quarry (NY), containing spectacular fossils in 3D - In a new OA study, graduate student Sarah Losso Harvard Organismic & Evolutionary Biology Museum of Comparative Zoology unveils the complex mechanisms behind their preservation! nature.com/articles/s4324…

🚨📄 Paper Alert 📄🚨 Our new paper about the early developmental stages of a 480 million years old arthropod from Morocco is out! We used synchrotron X-ray microtomography to see details of these ~ 2 mm long babies. Details in 🧵👇 1/7

Meet Setapedites abundantis, a 485 million years old arthropod described by Lorenzo Lustri, Pierre Gueriau and Allison Daley. This tiny animal is abundant (hence it's name) in some levels of the Fezouata Shale and is a distant relative of today's 🕷️🦂 📄👉nature.com/articles/s4146…

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. This week in Science: scim.ag/7u3

🚨 New Paper Alert! 🚨 We describe new material of Bunaia woodwardi, reassigning it to Offacolidae, and discuss a newly identified homology uniting Euchelicerata, Vicissicaudata, and Habeliida!

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 🥳

Published today in the Swiss Journal of Palaeontology our new work on trilobite phylogenetics. It is open access for everyone. sjpp.springeropen.com/articles/10.11…
