Did you know why dinosaurs became extinct

In world science, the extinction of dinosaurs is most often explained by "catastrophic" hypotheses. Dinosaurs (as well as ammonites and marine reptiles) could have been destroyed by volcanic activity, a meteorite impact, a supernova outbreak near the Solar System, and a drop in ocean levels. Russian paleontologists mostly adhere to the biosphere version: dinosaurs disappeared gradually due to the spread of flowering plants and the cooling of the climate.
