…I take it, then, you either
a) disagree with something in the paper I provided that relates Orstenotubulus to the lobopods on definitely a somewhat deeper level of morphology than you were looking at; or
b) you don’t think it provides any insights on Hallucigenia, despite both sharing paired spines and stub feet, the same features you were using to relate it to a purely hypothetical echinoderm quite different from contemporaries.
Because saying there’s no more solid connection without any such comment really makes it feel like the link counter is telling the truth, and you simply didn’t look at the one I offered you. I mean, I’m not saying it counts as certain, but it’s not purely speculative either.
