ari Marekodhi ekare aripo pane aya amphibians anobva kuLower Jurassic neLower Cretaceous.. Zvishoma zvinozivikanwa pamusoro pekuti dzakashanduka sei kubva ipapo kusvika nhasi.
mumuviri zvinhu
Muviri weCaecilian unonyatso kuenderana nekugara kwayo, hupenyu hwepasi pevhu. Kukura kwayo kweround pakati pe10 cm kureba uye kusvika mita nehafu. Havana mitezo uye yavo Muviri wakareba uye wakaita cylindrical kunge wenyoka kana gonye. Meso ake, kunyange anawo, haana maturo. Muviri waro wakaumbwa nemavertebrae mazana maviri uye muswe mupfupi kwazvo uye wakarongwa kuita zvindori zvakasiyana sehonye. Izvi zvindori, panguva imwe chete, zvakarongwa kuva zvindori zvechipiri uye zvepamusoro. The musoro wakatsetseka, ganda rakatsetseka uye rine miforo yakachinjika kunze kwemumusoro pakanyanya kuoma.
