Rhabdopleura graysoni Chapman, Durman and Rickards

Diagnosis according to Chapman, Durman and Rickards (1995, p. 295):

"Miniscule rhabdopleurid, with colony some 1 mm x 2 mm, comprising at least 9

zoecial tubes, each 0.10 mm in diameter, radiating from origin, or growing in

subparalle bundles; stolons and fuselli identified; fuselli 40 per mm; longest

zooidal tubes 1.25 mm, stolons ?0.02 mm wide, black; a basal structureless layer

probably present; branching not obvious away from origin; crumpled nature of

some tubes suggests they were upright zoecial tubes during life".
