As with ramose colonies, frondose forms were weakened when Sanctum laurentiensis mined out large chambers. |
|
This fossil has been reconstructed with a hypothetical stalk anchored in the substrate, as if supporting a frondose body in a reclined position. |
|
Several other specimens overlap underlying recumbent organisms or smaller frondose taxa. |
|
Those adapted to it, namely the radially organized frondose Petalonamae, anchored in the mat with their basal bulbs. |
|
Large chambers, such as those in frondose bryozoan colonies, accommodated a large number of organisms, perhaps representing several instars in multiple generations. |
