Whakarāpopototia te tuhinga:  E whakamahere ana nga kairangahau ki te keri i te 5,000 waewae (1,500 mita) i raro i te mata o te kokoru o Chicxulub i Mexico ki te ngana me te whakautu i te patai me pehea i mate ai nga dinosaurs. Ko te pūoko e tūmanakohia ana kia kitea e rātau ka āhei rātau ki te titiro whakamuri ki te wā 10 miriona ki te 15 miriona tau ki mua. Ka taea e tēnei te āwhina ki te whakamārama i te mea i tupu ki te waihanga i te kōhao - ā, mēnā i whakamatea e ia ngā rauropi. I ako ngā kairangahau o Ingarangi i te pānga o te aorangi i te 66 miriona tau ki muri (e whakaaturia ana i te whakaahua). I kitea e rātau kāore i nui te wera i te wāhi i pā mai ai te pānga ki Mexico ki te mura i te rauemi tipu. He iti iho i te meneti te roa o te pāmahana, he poto rawa hei whakaoho i ngā tipu. Ko te waahi paanga e kiia ana ko te 125 maero (200km) whanui o te kohao Chicxulub i tanumia i raro i te Yucatán Peninsula i Mexico. I te wā i patua ai e te kohinga whetū e ono māra te whanui (10 km) te wāhi e kiia nei ko Mekiko, tata ki te 66 miriona tau ki muri, i pāngia ngā tānara e ngā raruraru taiao, nāna rātou i noho whakaraerae. Kua whakapāha te kairangahau o mua ki te ariā i haere tahi mai he ahi ahi ao ki te aorangi i whakamate i nga dinosaurs. Kua kitea e tētahi rōpū kairangahau, kāore i ranea te wera i te wāhi i pā mai ai te pākahiko ki ngā tipu. E tohu ana i tō tātou māramatanga o te whakangaromanga nui i whakangaromia ai ngā kaihopu, kāore pea i te tino rite ki te whakaaro. 'Ko te kohanga pānga Chicxulub he whai wāhitanga pūtaiao tino mō te 20 tau mai i kitea ai,' Sean Gulick, o Te Whare Wānanga o Texas i Austin Institute mo Geophysics, ka mea ki Livescience. I hui mai tētahi rōpū pūtaiao o te ao i te wiki kua hipa ki Mérida, Mexico, kei roto i te kohanga Chicxulub 125 maero-whānui (200 kiromita), hei matapaki i a rātau mahere mō te kaupapa keri, i whakaritea kia tīmata i te puna 2016. E whakapono ana rātau, mēnā he toka nui ka tukituki ki te Ao i te tere nui, ka meinga e te tukinga te anga o te whenua kia pēnei i te wai, i te tīmatanga ka hanga i tētahi kohanga e kiia nei ko te kohanga o te wā poto (pēnei i te kōhanga e hanga ana i runga i te mata o te roto i muri i te maka o te toka ki roto), ā, ka rere anō te pokapū, he mea rānei...
