FIGURE 5 in Ovummuridae (calcareous microfossils) from the Much Wenlock Limestone Formation, Shropshire, UK

FIGURE 5. Photomicrographs of Arouxina pluricellata (A-F) and Samtlebenella circumcamerata (G-H) within the MWL Fm., these specimens are from Longville Stanway Track (A), Moorwood Quarry (B, C, E and H), Harton Hollow (D and G) and Strefford Quarry (H). (A) = Sectional cut through A. pluricellata highlighting the multiple hemispherical chambers (HC) surrounding the globular dorsal chamber (DC) and ventral chamber (VC). HC can form concentrically. Occasional apical apertures (ap) are observed within the DC.The bulbous growth are associated with several walls. (B) = Thickened A. pluricellata specimen with six HC surrounding the central DC and VC. Note the presence of pyrite within a few of the HC. Matrix comprised solely of sparite. (C) = An elongate A. pluricellata test with three HC. (D) = Specimen of A. pluricellata highlighting the disjointed nature of the surrounding HC. (E) = A. pluricellata with a single HC chamber but exhibits an ap within both VC and DC. (F) = A. pluricellata specimen with thinner walled HC compared to the walls surrounding the DC and VC. (G) = S. circumcamerata resembling Darth Vader's helmet. Presence of HC within the walls surrounding the DC. (H) = Thick walled specimen of S. circumcamerata with a partially preserved VC and two chambers (c) are visible within the walls surrounding the DC. Sparitic matrix = (sp). All scale bars equal 50 µm.
