Ovummuridae are calcareous egg-shaped microfossils of unknown biological affinity. There are limited observations in the literature due to their occurrence only within exceptionally preserved carbonate rocks. The first observation and subsequent erection of the family was via scanning electron microscope imagery; more recently standard light microscopy has been used successfully to observe these microfossils. In this study 124 polished and etched thin sections from various lithofacies from the Much Wenlock Limestone Formation were studied via...
