Well, trash. I already knew about these, but as fossils. This headline made me think they found a branch of them just growing in Scotland. But no, it is just the thing we already knew about. Not sure how they got any information that confirms they weren’t plants or fungi from fossils, but I guess that is the only newsworthy thing here. (Tubes, mostly looking at the branching of tubes and how they differ from any fruiting fungus is what I gather after reading the actual paper. I do think it is interesting that they also focused on how they are different from crustaceans. It would have been pretty interesting if those were crab trees.)
