He pakanga a te tainasoa?

Ko tētahi atu huarahi ki ngā rangahau paleontology ka kiia ko te "dinosaur blitz".
I tangohia te kupu nei i ngā tohunga koiora e whakarite ana i ngā "bio-blitzes". I roto i te bio-blitz, ka huihui ngā tūao ki te kohikohi i ngā tauira koiora katoa mai i tētahi kāinga motuhake i roto i tētahi wā kua tautuhia. Hei tauira, ka whakarite pea ngā bio-blitzers i te mutunga wiki ki te kohikohi i ngā tauira o ngā amphibians me ngā ngārara katoa e kitea ana i roto i tētahi awaawa maunga.
I roto i te pakanga-tāi-tāi-tāi, ko te whakaaro kia kohia te maha o ngā kōiwi tawhito o tētahi momo tāi-tāi-tāi kotahi mai i tētahi moenga kōiwi tawhito motuhake, mai i tētahi wā motuhake rānei. Mā te kohi i tētahi tauira nui o te momo kotahi, ka taea e ngā tohunga paleontology te rapu i ngā huringa hanganga tinana puta noa i te oranga o ngā mema o taua momo.

I whakakorikori te ao o ngā kaiwhai tainasoa i ngā hua o tētahi pakanga patu tainasoa i panuitia i te raumati o te tau 2010. I puta ake hoki he tautohetohe e kaha haere ana i ēnei rā.
Neke atu i te kotahi rau tau, kua tuhia e ngā tohunga paleontology ētahi peka e rua i runga i te rākau o te ora: tētahi mō Triceratops, tētahi mō Torosaurus. Ahakoa he rerekētanga i waenganui i ngā mea e rua, he maha ngā āhuatanga ōrite. He kai otaota rāua. I noho rāua i te wā o te Cretaceous Whakamutunga. I pihi ake ngā huruhuru wheua i muri i ō rāua mahunga, pērā i ngā whakangungu rakau.
I whakaaro ngā kairangahau he aha ngā mea ka whakakitea e te pakanga-aorangi mō ēnei momo mea hanga rite.

I roto i ngā tau tekau, i kohia ngā wheua Triceratops me Torosaurus i te rohe o Montana e kīia ana ko te Hell Creek Formation, he nui ngā kōiwi tawhito.
E whā tekau ōrau o ngā kōiwi tawhito i ahu mai i ngā Triceratops. Ko ētahi angaanga he rite te rahi ki ngā whutupaoro Amerikana. Ko ētahi he rite te rahi ki ngā motuka iti. Ā, i mate katoa rātou i ngā wāhanga rerekē o te oranga.
Mō ngā toenga o Torosaurus, e rua ngā mea i kitea: tuatahi, he iti noa ngā angaanga Torosaurus, tuarua, kāore i kitea he angaanga Torosaurus kāore anō kia pakeke, kāore anō hoki kia taitamariki. He angaanga pakeke nui katoa ngā angaanga Torosaurus. He aha i pērā ai? I a ngā tohunga moroiti e whakaaroaro ana ki te pātai, e whakakore ana i tētahi tūponotanga i muri i tētahi, ka mahue iho he whakatau kotahi e kore e taea te karo. Ehara a Torosaurus i te momo tainasoa motuhake. Ko te tainasoa kua roa nei e kiia nei ko Torosaurus, ko te momo pakeke whakamutunga o Triceratops.

I kitea te taunakitanga i roto i ngā angaanga. Tuatahi, i tātarihia e ngā kairangahau te hanganga whānui o ngā angaanga. I āta inehia e rātou te roa, te whānui, me te matotoru o ia angaanga. Kātahi ka tirotirohia e rātou ngā taipitopito moroiti pēnei i te hanganga o te mata me ngā huringa iti o ngā miro. I kitea i roto i tā rātou whakamātautau kua "whakahouhia rawatia" ngā angaanga Torosaurus. Arā, kua nui ngā huringa o ngā angaanga me ngā miro wheua o Torosaurus i roto i te oranga o ngā kararehe. Ā, ko taua taunakitanga o te whakahoutanga he nui ake i ngā taunakitanga i roto i te angaanga Triceratops nui rawa atu, ko ētahi o aua tohu he tohu kei te huri.
I roto i te horopaki whānui, e whakaatu kaha ana ngā kitenga o te pakanga dino-blitz he maha ngā tainasoa kua tautuhia he momo takitahi, engari he momo kotahi anake.
Mena ka tautokohia e ētahi atu rangahau te whakatau a Torosaurus-i-te-pakeke-Triceratops, ko te tikanga kāore pea ngā tainasoa o te Wāhanga Karāhe-Mutunga i te kanorau pērā i te whakaaro o te nuinga o ngā tohunga pūtaiao. Mēnā he iti ake ngā momo tainasoa, ko te tikanga he iti ake tō rātou urutau ki ngā huringa o te taiao, me/ranei kua heke kē tō rātou kaha. Ahakoa pēhea, he nui ake te tūponotanga o ngā tainasoa o te Wāhanga Karāhe-Mutunga ki te ngaro i muri i tētahi āhuatanga kino ohorere i whakarerekē i ngā pūnaha huarere me ngā taiao o te Ao, i tētahi rōpū kanorau ake.
