Bioclasts have mixed orientation, but large ammonoids and ramose corals are invariably concordant.
One of these species, a ramose form with thin branches, was not found in the coral reef zone lower in the section.
As with ramose colonies, frondose forms were weakened when Sanctum laurentiensis mined out large chambers.
In the root mantle, the borings are somewhat ramose and wind around the roots in the ground tissue.
The coral reef horizon is 19 m thick and, based on observation of weathered exposures of some of the massive and ramose coral colonies, it probably had a meter or more of relief on its surface at the peak of reef development.
Origin
Late 17th century: from Latin ramosus, from ramus 'branch'.
