Geological evidences of the catastrophe
In the "Catastrophe at the Cretaceous-Palaeogene boundary (66 -65 million years ago)" are considered geological evidences and benchmarks of the catastrophe:
- Volcanism outburst (volcanic eruptions),
- Accumulation of boundary clay,
- Iridium anomaly,
- Accumulation of soot,
- Change of a regime of sedimentation,
- Climatic alterations,
