Evolution of Amaurolithus: Amaurolithus delicatus marking the Messinian bottom
After a complete study of the sediment samples from Ocean Drilling Program (ODP) Sites 999 and 1237 in the Caribbean Sea and Eastern Pacific Ocean in order to monitor the evolution of ceratoliths. The First Occurrence of Amaurolithus delicatus marks the bottom of the Messinian Stage. The first ceratholith, A. primus, has two arms and a horseshoe […]
Origin of the ceratolith genus Amaurolithus
Sediment samples from Ocean Drilling Program (ODP) Sites 999 and 1237 in the Caribbean Sea and Eastern Pacific Ocean were studied to monitor the evolution of ceratoliths from 7.4 Ma to 6 Ma. Orthorhabdus rugosus shows high variability at the end of the Tortonian to the Early Messinian (7.35 Ma to 6.91 Ma), resulting in […]
