WebNov 19, 2024 · The Early Pliocene record shows significant paleobathymetry changes due to climate change, and the first interval shows depths > 100 m and dominance of Planulina ariminensis and Valvulineria bradyana species. This increase may be due to the glacio-eustatic sea-level rise (deglaciation) from 5.5 Ma. WebApr 13, 2024 · This study uses a multiproxy design to document vegetation structure from nine Early Miocene mammal site complexes across eastern Africa. Results demonstrate that between ~21 and 16 Ma, C 4 grasses were locally abundant, contributing to heterogeneous habitats ranging from forests to wooded grasslands.
