And last, a redescription of the Early Devonian eurypterid Leiopterella tetliei Leibniz-Institut DSMZ buff.ly/3GFhMlA

The Waukesha Biota is a Silurian Lagerstätte preserving many soft-bodied organisms, but rarely any hard carapaces. The scene below shows only a part of its rich fauna. (It's my first 3d paleoart scene, and I think it turned out well.) #paleoart #silurian #3dart

Jenny, Whitey and I discuss trace #fossils for @ShapeofLifeorg : shapeoflife.org/video/paleonto…

A reconstruction of the Early Devonian chasmataspidid (chelicerate) Forfarella mitchelli from Scotland, described by Jason, Lyall and me.

And so concludes this short and relaxing formation #paleostream! The Soom Shale is a late Ordovician lagerstätte with few fossils but often times exceptional preservation. This is one of the few places we have conodont fossils from with more than just the "teeth"

Richard co-supervised MSc and PhD students with me and we spent many hours discussing #fossils, popular science writing and TV presentation. theguardian.com/science/2025/m…

I suspect Keurbos may relate to Acheronauta, as mentioned in: K.C. Gass & S.J. Braddy. 2023. The Waukesha Biota: A wonderful window into early Silurian life. Geology Today 39 (5): 169-175; doi: 10.1111/gto.12447i onlinelibrary.wiley.com/doi/full/10.10…

New video on Jaekelopterus; great CGI but a distinct AI feel and images don't always match the narration. Name spelt wrong (although it is pronounced Yay-kel-op-ter-us). See my Facebook profile for comments youtu.be/AFvynBcN3Gw?fe…

Sketchfab has various 3D models of eurypterid fossils and reconstructions you can manipulate (rotate, scale etc): sketchfab.com/search?q=euryp…

Cyclopygid #trilobite phylogeny, dedicated to Euan and Richard. Taihungshaniidae basal to Nileidae and Cyclopygidae. Adapted to pelagic lifestyle (larger eyes, lost segments, decreased size and improved streamlining) as moved into deeper water. doi.org/10.1080/089129…

New paper accepted on giant Chinese eurypterids in Journal of Earth Science

New paper accepted on Chinese pterygotid eurypterids in Journal of Paleontology.

Nice reconstruction of #Jaekelopterus, the largest ever arthropod (2.59 m) long. It's probably more closely related to Pterygotus than Acutiramus. For details see: sci.news/paleontology/p…
