Monospecific biostromes in the Campanian-Maastrichtian
“Highlights
- Four monospecific biostromes recorded in the Campanian-Maastrichtian Duwi Formation of Egypt.
- The taphonomic features were quantitatively analyzed (multivariate analysis, shell size and orientation).
- The oyster parabiostromes occupy early TST, while the heterodont bivalve autobiostromes occupy MFZ.
- The monospecific nature is interpreted to be a consequence of high productivity and associated anoxia.”
