It's #TrilobiteTuesday and old friends sent me this after a visit to the Field Museum, so I guess I'm obliged to share? Or visit again, whatever. Apparently the Pokémon fossil exhibit is really good too.

My friend Lorenzo Lustri and I made this video about his study on Urokodia aequalis, an exceptionally preserved Early #Cambrian arthropod from the Chengjiang Biota, published yesterday in #Nature. 👉 Link to the paper: www.nature.com/articles/s41... #palaeontology #fossil #cambrian

Just realised it's #TrilobiteTueaday so here's a pic of a little beastie I saw that was set into the paving in the new gardens @nhm-london.bsky.social. Not sure what it is; looks a bit Paradoxides-like to me.
I forgot to post a picture of this trilobite found by a friend — and now it’s mine. Really nice preservation and colors. In the thread you can see another photo with the negative. #Trilobite #Fossil #Paleontology #Geology
🚨🌋 New collaboration paper! I’m really happy to have contributed to this paper in which we reconstruct the facies architecture and emplacement dynamics of a Cambrian submarine basaltic lava-flow system from Cumbres Mayores, Huelva (SW Spain). #geology #volcanology #pillowlava #cambrian #spain
Overly honest museum labels #1 "Graptolites which look as if someone has scribbled all over the rock!" Leptograptus capillaris, on display in National Museum of Scotland, Edinburgh #FossilFriday 🌍⚒️✏🧪🔬
🚨NEW STUDY DROP🚨 Another bivalved Arthropod has been described as, Cassicaris clarksoni. based on over 200 specimens from the early Cambrian (Stage 3) Xiaoshiba Lagerstätte in Kunming, China. It had a bunch of spines running down its tail, with paddle-shaped organs at the end.
Welcome back to #trilobitetuesday Here is a slab of shale with trilobites Olenellus chiefensis. This comes from the Lower Cambrian (Series 2, Stage 3) Combined Metals Member in the Pioche Shale in Lincoln County, Nevada.

Something tiny for #TrilobiteTuesday This is a Meadowtownella trentonensis from the famous Walcott-Rust quarry in New York. This was one of the first sites to show trilobite legs. Charles Walcott later discovered the Burgess Shale in Canada. This specimen is upside down and only 7 mm long.

A flower beetle in baltic amber. We hope to raise money for a museum microscope so kids can examine insect specimens like this one!
