E kholo ka ho fetisisa e ka lekana le mithara e le 'ngoe. Qetellong, ho lokela ho hlokomeloe hore letlalo la Triceratops le ne le fapane le letlalo la li-dinosaurs tse ling, joalo ka ha lithuto tse ling li supa hore e kanna eaba e koahetsoeng ke boea.

5. Li-protoceratops

Protoceratops ke e 'ngoe ea li-dinosaurs tse nyane ka ho fetesisa tseo re li bonts'ang lenaneng lena mme tšimoloho ea tsona e Asia. Ithute haholoanyane ka eona:

Etymology ea Protoceratops

Lebitso Li-protoceratops e tsoa ho Segerike mme e thehiloe ka mantsoe "proto"(pele),"cerat"(manaka) le"oops"(sefahleho), ka hona e ka bolela"hlooho ya pele e manaka". Dinosaur ena e ile ea aha lefats'eng lipakeng tsa AD 84 le 72, haholo-holo linaha tsa kajeno tsa Mongolia le China. Ke e 'ngoe ea li-dinosaurs tsa khale ka ho fetisisa tse nang le manaka mme mohlomong ke moholo-holo oa tse ling tse ngata.

Ka 1971 mesaletsa e sa tloaelehang e fumanoe Mongolia: Velociraptor e neng e amohela Protoceratops. Khopolo ea boemo bona ke hore ka bobeli ba ka be ba shoele ba loana ha sefefo sa lehlabathe kapa leholiotsoana le ba oela. Ka 1922, leeto le eang Lefeelleng la Gobie le ile la sibolla lihlaha tsa Protoceratops, mahe a pele a dinosaur a fumanoeng.

Ho fumanoe mahe a ka bang mashome a mararo ho se seng sa lihlaha, e leng se etsang hore re lumele hore sehlaha sena se ne se arolelanoa ke tse tšehali tse 'maloa tse neng li tlameha ho se sireletsa ho libatana.
