A newly described fossil from Utah reveals a pincer-wielding sea creature from the Cambrian. It may be one of the oldest relatives of spiders, scorpions and horseshoe crabs (Not an April Fool's joke, I swear!) 🕷️ 🦂 Latest for @NYTScience : nytimes.com/2026/04/01/sci…

The 2023-2024 Annual Report of the MCZ is now available at bit.ly/3CAeSB8 The cover features the Kronosaurus specimen on display at @HarvardMuseums (image taken by Thomas Earle, Harvard Staff Photographer).

@PhylumBryozoa Thanks Sergio, much appreciated!

@PlLife2 Many thanks! I am glad that you liked and were interested in the topic. The hederelloids are the other group that I mentioned. Here is a superb review about this group of organisms: researchgate.net/publication/25…

I am very excited as tomorrow I will be speaking about bryozoans and other creatures at the Harvard University Invertebrate Paleobiology Lab seminar.

Best conference logo ever!!! 😍 The Invertebrate Paleo Lab @MCZHarvard @HarvardOEB is totally visiting beautiful Chile 🇨🇱 next year to share some Cambrian and Ordovician creatures 🤩

🚨Another little promotional piece, this time from our collaborators in Utah. I hope this blog post will help, even in a small way, to raise awareness among Utahns about the fantastic Cambrian paleontological archive their state holds. @NHMU @BLMUtah nhmu.utah.edu/articles/2024/…

🚨 A bit of promotion for the work we do on the mid-Cambrian Marjum biota in Utah. Feel free to contact me if you want to know more. Thanks to the @royalsociety and our collaborators at the @MCZHarvard @NHMU @BLMUtah. royalsociety.org/blog/2024/11/m…

The MCZ was awarded a new digitization grant and we have two new positions to fill! We are looking for curatorial assistants (one full-time, one part-time) to rehouse and digitize our invertebrate microscope slide collections. bit.ly/48dxQJJ and bit.ly/48dwqy

@Davey_F_Wright @alison_cribb @Royalcom1851 Really enjoyed the talk as well. Congrats on the publication of this paper 👏

@alison_cribb @Royalcom1851 Looking forward to reading this. Very cool talk at GSA!

The MCZ and @HarvardOEB welcome three new Biodiversity Postdoctoral Fellows this month: Valentine Bouju (entomology), Rodrigo T. Figueroa (vertebrate paleontology) and Cata Romero-Ortiz (invertebrate zoology). Applications for 2025 fellows are due Sept 30! bit.ly/3ygxDHO

@Paleojim @BLMUtah @utahgeological @UtahPaleo @NHMU Here are a few links for the people interested: nhmu.utah.edu/articles/2023/… nhmu.utah.edu/articles/2023/… nhmu.utah.edu/articles/2023/… Another piece should be online soon ;)

@Paleojim @BLMUtah @utahgeological @UtahPaleo Agree. I believe Utah's remarkable Cambrian heritage is often overshadowed by its renowned dinosaur fossil record. But we are working on its popularization within the state with @NHMU. Hopefully, we'll be given a chance to give some talks there and at UU soon.

Utah' Cambrian record is a critically significant record of the initial diversification of multicellular life. The story is largely ignored in Utah. @BLMUtah @utahgeological @UtahPaleo

The supplementary material associated to this publication, including many additional illustrations, will be available soon at: rs.figshare.com/articles/datas…

We are grateful to: @BLMUtah and @NHMU for a productive collaboration, @MCZHarvard for supporting our fieldwork (Putnam Expedition Grants) and the publication of this paper (Wetmore Colles Fund), @MCZpaleo for invaluable curatorial assistance, and palaeoartist @franzanth

🚨Paper alert🚨Meet Polygoniella turrelli, our latest addition to the remarkable Cambrian Marjum Biota of Utah. This 500-million-year-old sponge displays a complex anatomy that has no equivalent amongst poriferans of that time. @Ldelmouro @InvertebratePal doi.org/10.1098/rsos.2…
