My Answer- The film indicates that the M.U.T.O. eggs / spores require the radiation from the bodies of the Godzilla species, and as the Godzilla species became extinct, the M.U.T.O.s eventually became extinct as well, as a parasite can not live without a host least at one stage of your life. Explaining: The bodies of the Godzilla species are essentially a biological nuclear reactor, which emit radiation. Remembering that, unlike Godzilla, M.U.T.O.s did not evolve to absorb radiation from the Earth's core, but evolved to parasitize the Godzilla race (they have developed mechanisms to adapt to their hosts, as well as many parasitic species in nature). In the case, M.U.T.O.s developed mechanisms specifically to combat Godzilla and use it to their advantage, that is, they killed Godzillas and used their giant and radioactive corpses to incubate and feed their offspring. What I mean is that M.U.T.O.s are an unconventional and rather strange example of parasites (NOTE: M.U.T.O.s are designed to be kaijus "UFOs" in the sense that they are quite strange kaijus as well as having a technological and almost alien appearence), it can be said that MUTOs are a mixed parasite / predator. Parasite in the sense of using the Godzilla species, and possibly other species of Kaijus, as a source of radiation to ensure their survival, and Predator in the sense of competing with the Godzilla species for food / radiation and determining who would be the apex predator of their ecosystem.
