Coral - Acervularia

myminifactory

Silurian Colonial Coral Acervularia Ananas. Discovered in Shropshire, likely originating from Wenlock Edge. Acervularia Pentagona is an extinct species of Tabulate Coral. Tabulata, commonly referred to as Tabulate Corals, are an order of extinct forms of coral. They are almost always colonial, forming colonies of individual hexagonal cells known as corallites defined by a skeleton of calcite, resembling a honeycomb in appearance. Adjacent cells are connected by small pores. Their distinguishing feature is their well-developed horizontal internal partitions (tabulae) within each cell, but reduced or absent vertical internal partitions (septa). They are generally smaller than rugose corals, but vary significantly in shape, ranging from flat to conical to spherical. Captured using a Canon 5DS R and Stackshot 3x with turntable to provide 108 images, which were then processed using Agisoft Photoscan at high levels. This object is scanned by Fossils in Shropshire.
