| This fossil has been reconstructed with a hypothetical stalk anchored in the substrate, as if supporting a frondose body in a reclined position. |
| There are several species which are related to the frondose polyporus which occur in this country as well as in Europe. |
| In fact we may expect a form reduced to an axis, a few ramenta, a frondose dilatation, and one punctum of reproductive organs. |
| Several other specimens overlap underlying recumbent organisms or smaller frondose taxa. |
| Large chambers, such as those in frondose bryozoan colonies, accommodated a large number of organisms, perhaps representing several instars in multiple generations. |
| As with ramose colonies, frondose forms were weakened when Sanctum laurentiensis mined out large chambers. |
