For #CanadaDay 🇨🇦 i wanted to share this iconic #Ediacaran fossil. #Haootia quadriformis which was discovered by the late Professor Martin Brasier close to Port Union in @discoverygeoparknl.bsky.social. The second oldest crown group staurozoan cnidarian animal in the world. Just look at those 💪.

One of my favorite animals is the staurozoan, Haliclystus. It looks sort of like a sea anemone polyp but is instead a stalked medusa! Strange beast. They are patchy in both space in time, at least where I see them in #NorCal. Always makes me happy to find them!

Ooooh the rare Staurozoan representation

This #fossilfriday is brought to you by the holotype of the oldest fossil cnidarian Mamsetia manunis from @discoverygeoparknl.bsky.social . This summer we have worked with Champney’s West Mini aquarium on a new Geosite which includes a cast of this specimen. It was torn prior to fossilization

This #FossilFriday i wanted to share this tiny #Staurozoan fossil from the Ediacaran of Newfoundland. It was the paratype of #Haootia but now belongs to #Mamsetia . We consider that it might be the #Stauropolyp. See the coronal muscle of the calyx & 1 arm. compare the arm of a modern #Lucernaria
