Stromatoporoid

myminifactory

Stromatoporoid, overgrowing a small colony of the tabulate coral Favosites. Found on Wenlock Edge. Stromatoporoidea is a class of aquatic invertebrates common in the fossil record from the Ordovician through the Devonian. They were especially abundant in the Silurian and Devonian.  These invertebrates were important reef-formers throughout the Paleozoic and the Late Mesozoic. The group was previously thought to be related to the corals and placed in the Phylum Cnidaria. They are now classified in the sponges (Phylum Porifera), specifically the sclerosponges. There are numerous fossil forms with spherical, branching or encrusting skeletons of laminated calcite with vertical pillars between the laminae. Imaged 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
