Toxic Ocean Conditions During Major Extinction 93.9 Million Years Ago Quantified: Doesn’t Take Much Sulfide to Impact Ocean Life

Oxygen in the atmosphere and ocean rose dramatically about 600 million years ago, coinciding with the first proliferation of animal life. Since then, numerous short lived biotic events — typically marked by significant climatic perturbations — took place when oxygen concentrations in the ocean dipped episodically. The most studied and extensive of these events occurred…

Scientists Gain New Insights Into Dolphin’s Evolutionary History and Conversation
