No state change in pelagic fish production and biodiversity during the Eocene-Oligocene Transition
Supplementary datasets of ichthyolith accumulation rates, as well as updated accumulation rate calculations for silica and barium from published literature, compiled for the following manuscript on the GTS2012 age model: The Eocene-Oligocene (E/O) boundary ~33.9 million years ago, has been described...
