Some large productid brachiopods for #FossilFriday ⚒️🧪
While most brachiopods tend towards the small side for benthic invertebrates, often just a few mm to cm, late Paleozoic productids could get relatively large. There's a good case for the bizarre reef-forming taxa being photosymbiotic.

What is this organism?
A plant?🌱No.
An animal?🐮 Yes.
A coral?🪸Not even close!
This is a moss animal, a colonial marine invertebrate related to lamp shells (Brachiopoda) and horseshoe worms (Phoronida).

TLDR: We found very weak support for the (Brachiopoda,Mollusca,(Annelida,(Platyhelminthes,Nemertea))) tree. We do not know where the root of Spiralia goes. The spiralian phyla appeared in a very hard to resolve rapid radiation.
