Mō te wā roa, kua awehia te tangata e te ahua o ngā tainasoa i runga i te mata, nō reira e kiia ana ko te T-rex te tihi o ngā momo tainasoa maha. E ai ki ngā rangahau whaipara tangata, he tika te T-rex kia tū ki te tihi o te mekameka kai. Ko te roa o te T-rex pakeke he neke atu i te 10 mita, ā, he nui te kaha ngau whakamiharo hei haehae i ngā kararehe katoa kia rua. Ko ēnei pito e rua anake he nui hei meinga te tangata kia karakia ki tēnei tainasoa. Engari ehara i te momo tainasoa kai kikokiko kaha rawa atu, ā, ko te mea kaha ake pea ko Spinosaurus.
Ki te whakatauritea ki a T-Rex, he iti ake te rongonui o Spinosaurus, he mea e kore e taea te wehe atu i te āhua tūturu o te keri whenua. Mai i te āhua o te keri whenua o mua, ka taea e ngā tohunga paleontology te tiki atu i ngā kōrero mō Tyrannosaurus Rex mai i ngā kōiwi tawhito i a Spinosaurus, e āwhina ana i te tangata ki te whakaahua i tōna āhua. Kāore anō kia whakatauhia te āhua tūturu o Spinosaurus. I roto i ngā rangahau o mua, kua tautuhia e ngā tohunga paleontology a Spinosaurus hei tainasoa kai nui theropod i waenganui o te wā Cretaceous i runga i ngā kōiwi Spinosaurus i keria. Ko te nuinga o ngā whakaaro o te tangata mōna i ahu mai i te mata kiriata, i ngā whakaahua kua whakahokia mai rānei. Mai i ēnei raraunga, ka kitea he rite a Spinosaurus ki ētahi atu kai kikokiko theropod engari ko ngā tuaiwi tuara motuhake i tōna tuara.
E ai ki ngā tohunga paleontology he tirohanga hou mō Spinosaurus
Nō te whānau Spinosaurus te Baryonyx i roto i te whakarōpūtanga. I kitea e ngā tohunga paleontology he unahi ika i roto i te puku o tētahi kōiwi Baryonyx, ā, i whakaarohia e rātou ka taea e Baryonyx te hī ika. Engari kāore tonu i te kī he ika wai ngā spinosaur, nā te mea he pai hoki ki ngā pea te hī ika, engari ehara rātou i te kararehe wai.
Nō muri mai, ka whakaaro ētahi kairangahau kia whakamahia ngā isotopes hei whakamātautau i a Spinosaurus, me te tango i ngā hua hei taunakitanga hei whakatau mēnā he tainasoa wai a Spinosaurus. Whai muri i te tātaritanga isotopic o ngā kōiwi Spinosaurus, i kitea e ngā kairangahau he tata ake te tohatoha isotopic ki tērā o ngā mea ora wai.
I te tau 2008, i kitea e Nizar Ibrahim, he tohunga mō ngā kararehe tawhito i Te Whare Wānanga o Chicago, tētahi rōpū o ngā tūpuna Spinosaurus he tino rerekē i ngā tūpuna e mōhiotia ana i tētahi maina i Monaco. I hangaia tēnei puranga tūpuna i te mutunga o te wā Cretaceous. Mā te rangahau i ngā tūpuna Spinosaurus, e whakapono ana te tīma a Ibrahim he roa ake, he kikokore ake te tinana o Spinosaurus i tō te mea e mōhiotia ana i tēnei wā, he rite te waha ki tō te korokotairo, ā, tera pea kua tupu he parirau. Mā ēnei āhuatanga e tohu ana he kararehe wai, he kararehe amphibian rānei te Spinosaurus.
I te tau 2018, i kitea anō e Ibrahim mā rātou ko tana tīma ngā tūpuna Spinosaurus i Monaco. I tēnei wā, i kitea e rātou tētahi tuaiwi me ngā maikuku o te hiku Spinosaurus kua tiakina pai. I tātarihia hohonutia e ngā kairangahau ngā tuaiwi hiku o Spinosaurus, ā, i kitea he rite tonu ki tētahi wāhanga tinana e puritia ana e ngā mea ora wai. Mā ēnei kitenga ka puta he taunakitanga anō kāore a Spinosaurus i te mea ora whenua, engari he tainasoa ka taea te noho i roto i te wai.
iSpinosaurushe tainasoa whenua, he tainasoa wai rānei?
Nō reira, he tainasoa whenua a Spinosaurus, he tainasoa wai, he tainasoa whenua rānei? Kua nui ngā kitenga rangahau a Ibrahim i ngā tau e rua kua pahure ake nei hei whakaatu ehara a Spinosaurus i te mea hanga whenua i te tikanga katoa. Nā roto i te rangahau, i kitea e tana tīma kua tupu ngā tuaiwi o te hiku o Spinosaurus i ngā taha e rua, ā, ki te hangaia anō, ka rite tōna hiku ki te rā. Hei tāpiri, he tino ngāwari ngā tuaiwi o te hiku o Spinosaurus i te taha whakapae, ko te tikanga ka taea e rātou te whakakorikori i ō rātou hiku i ngā koki nui hei whakaputa i te kaha kauhoe. Heoi, kāore anō kia whakatauhia te pātai mō te tuakiri tūturu o Spinosaurus. Nā te mea kāore he taunakitanga hei tautoko i te "He tainasoa wai katoa a Spinosaurus", nō reira he tokomaha ake ngā tohunga paleontology e whakapono ana he mea hanga whenua pērā i te korokotairo.
I te katoa, kua whakapau kaha ngā tohunga pūtaiao tawhito ki te ako i a Spinosaurus, me te hura haere i te mea ngaro o Spinosaurus ki te ao. Mēnā kāore he ariā me he kitenga e whakararuraru ana i te hinengaro taketake o te tangata, ki taku whakaaro kei te whakaaro tonu te nuinga he kai kikokiko whenua a Spinosaurus me Tyrannosaurus Rex. He aha te āhua tūturu o Spinosaurus? Me tatari tātou kia kite!
