Help needed! I'm looking for a 3D model of bryozoans to showcase at a science fair (3D printable). I want to bring these 'moss animals' to life for the general public! If you have a file or a recommendation, please let me know.

Years ago I was obsessed with these Antarctic "tulips"-eventually learned they were TUNICATES, Molgula pedunculata #tunicateTuesday Such crazy lookin' things! www.researchgate.net/publication/...

Our digitized Lophophorata data (now mostly #bryozoa, some #brachiopoda) are online at GBIF, this is just the beginning! More coming! www.gbif.org/dataset/82e6...

When I started my PhD ~10 years ago, only 2/5 echinoderm groups (the star-shaped sea stars and brittle stars) had genome-scale phylogenetic datasets. I am proud to say that the quest to complete the clade is now over doi.org/10.1098/rsos...

The biggest privilege afforded to men in positions of power is that of being dumb. There are people willing to accept the excuse that a world-class researcher neglected to do a 10-minute Google search on a sponsor, in the 2010s, as part of the process for accepting research funding.

#FossilFriday Eocene bryozoan Biselenaria offa first described by J.W. Gregory (1864–1932). Gregory was a geologist and explorer who published on the African Rift Valley and came close to being the leader of the tragic Terra Nova expedition to Antarctic in which Robert Falcon Scott and others died.

I'm glad to share our new study on the nature of distributions of gaps in empirical geochronologies of geological section as a function of time scale. Measurements of proxies are highly uneven if measured through time. 1/5  www.nature.com/articles/s43... 🧪 #Geology ⚒️ #Paleobio #EvoBio

Recently described "cookie" star Plinthaster australis from the #coralseafrontiers expedition! Originally known only from New Caledonia!

The first book for children to mention #MaryAnning was probably Maria Hack's 1832 Geological Sketches, during Mary's lifetime. She's popular today: in the last 10 years alone there have been over 40 books about her for young readers and she's featured in over 40 other children's books in that time.

#FossilFriday Graptolites are extremely useful as zonal fossils in the Ordovician and Silurian. Some look like pencil marks but better preserved examples, like this Monograptus priodon from the Wenlock of Scotland, resemble miniature saw blades.

Something very different for the last #MolluscMonday of 2025 – a montage of record album covers featuring ammonites. I’m sure there must be more.
