FIGURE 3. Photomicrographs of Ovummurus duoportius within the MWL Fm. showing this species typical morphology and characteristic. These specimens are from: Longville Stanway (A and B) and Moorwood Quarry (C and D). (A) = Ovummurus duoportius exhibiting two chambers (C1 and C2) separated by a septal structure (ss) with an apical aperture (ap) present in C2. All specimens here are found within a sparitic (sp) grainstone matrix. (B) = O. duoportius with thickened. (C) = Longitudinal cross section showing the equal-sized chambers present within O. duoportius. (D) = O. duoportius specimen with pyrite growth within C2. All scale bars equal 50 µm.
