This is evidenced by the extinction cycle with a period of ~140 million years, although it was dimly manifested (Rohde, Muller, 2005), which can be associated with the frequency of glaciations preceding extinctions (Veizer et al., 2000); as well as by the extinction cycle with a period close to 26–27 million years, which was manifested during the last 250 million …This extinction was perhaps caused by glaciation or increased volcanism on Earth.
