Hello DrDave,   Welcome to our Fossil Forum.

 

This is the most recent literature on Seaweeds from the Bertie. I cannot find a link with free access. The Abstract will show if it is something of interest.

Hope it helps somewhat.  John  (fossilcrazy)

It appears to be Inocaulis lesquereuxi

 

According to this new paper it is now classified as alga.

For specimens of the Late Silurian taxon Inocaulis lesquereuxi, however, optical microscopic and SEM-BSE investigations indicate that the tubes have an intertwined, but not anastomosing habit and closed endings (Figure 3a,d).  On the basis of these findings, I. lesquereuxi is herein regarded as an alga rather than a metazoan, with a form and construction broadly comparable to that of Buthotrephis newlini and B. divaricatus from the Pridolian of Indiana (White, 1902).

Thanks Scott.

the elucidation of a correct assignment of inc.sedis is always fascinating
