What caused the Devonian mass extinction?
No one knows for sure. Some people believe that an asteroid earlier in time hit Earth and caused massive climate change that killed off reptiles, but spared dinosaurs. Others believe that it was simply climate change.
What are facts about the devonian period?
The Devonian Period occurred approximately 419-359 million years ago and is known as the "Age of Fishes" due to the diversification of fish species. It was also a time of significant plant evolution, with the first forests appearing. The period ended with a mass extinction event that affected marine life.
How did the Phacops rana become extinct?
The Phacops rana, a species of trilobite, became extinct during the end-Devonian mass extinction, which was likely caused by a combination of climate change, volcanic activity, and a drop in sea levels. These environmental changes likely disrupted the trilobite's habitats and food sources, leading to their extinction.
What is the period after Devonian Period known as?
The period after the Devonian Period (416 to 359.2Ma) is the Carboniferous Period (359.2 to 299Ma).
What are the periods that divide the early paleozoic?
