Oppelismilia
The solitary scleractinian coral Opoetismitie, up
to 5cm/2in across, is a relatively rare fossil from
rocks of Upper Triassic to Jurassic times in the
Americas and Eurasia. This small, conical coral
grew in soh, muddy conditions that resulted in
frequent uprooting. Thus, it was never able to
establish firm anchorage and develop substantial
reef communities.
