According to the new research, the landmass extinction coincides with the disappearance of the ocean life population as well. As per a report in The Weather Channel, palaeontologists, while studying the extinction pattern of dinosaurs found that the extinction of marine life was not random, but rather occurred periodically, which led to the disappearance of nearly 90 percent of marine species in a 26-million-year cycle. The extinctions also align with major asteroid impacts and volcanic activity. Image: Pixabay
