He pana pua dinosaur?

ʻO kekahi ʻano hana i nā haʻawina paleontological e kapa ʻia ʻo ka "dinosaur blitz."
Ua lawe ʻia ka huaʻōlelo mai nā mea olaola e hoʻonohonoho ana i nā "bio-blitzes." Ma kahi bio-blitz, hōʻuluʻulu nā mea manawaleʻa e hōʻiliʻili i nā hāpana olaola āpau mai kahi wahi noho kikoʻī i loko o kahi manawa i ho'ākāka ʻia. No ka laʻana, hiki i nā bio-blitzers ke hoʻonohonoho i ka hopena pule e hōʻiliʻili i nā hāpana o nā amphibians a me nā reptiles āpau i hiki ke loaʻa ma ke awāwa mauna.
I loko o kahi dino-blitz, ʻo ka manaʻo nui ka hōʻiliʻili ʻana i nā mōʻalihaku he nui o kahi ʻano dinosaur hoʻokahi mai kahi moena mōʻalihaku kikoʻī a i ʻole mai kahi manawa kikoʻī e like me ka hiki. Ma ka hōʻiliʻili ʻana i kahi hāpana nui o ka ʻano hoʻokahi, hiki i nā paleontologists ke nānā i nā loli anatomical i ke ola o nā lālā o ka ʻano.

Ua hoʻopilikia nā hopena o hoʻokahi dino-blitz, i hoʻolaha ʻia i ke kauwela o 2010, i ka honua o nā mea hahai dinosaur. Ua hoʻonāukiuki pū lākou i kahi hoʻopaʻapaʻa e huhū nei i kēia lā.
No nā makahiki he hoʻokahi haneli a ʻoi, ua kahakiʻi nā paleontologists i ʻelua lālā kaʻawale ma ka lāʻau dinosaur o ke ola: hoʻokahi no Triceratops a hoʻokahi no Torosaurus. ʻOiai he ʻokoʻa ma waena o nā mea ʻelua, he nui nā ʻano like like o lāua. He mau mea ʻai lau nahele lāua ʻelua. Noho lāua ʻelua i ka wā o ka Late Cretaceous. Ua kupu mai nā ʻōniʻoniʻo iwi, e like me nā pale, ma hope o ko lāua mau poʻo.
Ua noʻonoʻo nā mea noiʻi i ka mea e hōʻike ai kahi dino-blitz e pili ana i nā mea like.

I loko o kahi manawa he ʻumi makahiki, ua loaʻa i ka ʻāina waiwai i nā mōʻalihaku kahiko i ʻike ʻia ʻo Hell Creek Formation nā iwi o Triceratops a me Torosaurus.
He kanahā pakeneka o nā mōʻalihaku i loaʻa mai Triceratops. Ua like ka nui o kekahi mau iwi poʻo me nā pōpeku ʻAmelika. ʻO kekahi ua like ka nui me nā kaʻa liʻiliʻi. A ua make lākou a pau i nā pae like ʻole o ke ola.
No nā koena o Torosaurus, ʻelua mau ʻoiaʻiʻo i kū mai: ʻo ka mua, ua kakaikahi nā mōʻalihaku Torosaurus, a ʻo ka lua, ʻaʻohe iwi poʻo Torosaurus ʻōpiopio a ʻōpiopio paha i loaʻa. He iwi poʻo makua nui kēlā me kēia iwi poʻo Torosaurus. No ke aha mai ia? I ka noʻonoʻo ʻana o nā paleontologists i ka nīnau a kāpae i kekahi hiki ma hope o kekahi, ua waiho ʻia lākou me hoʻokahi hopena hiki ʻole ke pale ʻia. ʻAʻole ʻo Torosaurus he ʻano dinosaur ʻokoʻa. ʻO ka dinosaur i kapa ʻia ʻo Torosaurus no ka manawa lōʻihi ʻo ia ke ʻano makua hope loa o Triceratops.

Ua loaʻa ka hōʻoia ma nā iwi poʻo. ʻO ka mea mua, ua kālailai nā kānaka noiʻi i ke ʻano kino nui o nā iwi poʻo. Ua ana pono lākou i ka lōʻihi, ka laulā, a me ka mānoanoa o kēlā me kēia iwi poʻo. A laila ua nānā lākou i nā kikoʻī microscopic e like me ke ʻano o ka ʻili a me nā loli liʻiliʻi i nā frills. Ua hoʻoholo kā lākou hoʻokolokolo ʻana ua "hoʻoponopono hou ʻia" nā iwi poʻo o Torosaurus. I nā huaʻōlelo ʻē aʻe, ua loli nui nā iwi poʻo a me nā frills iwi o Torosaurus i ke ola o nā holoholona. A ʻo kēlā hōʻike o ka hoʻoponopono hou ʻana ua ʻoi aku ka nui ma mua o ka hōʻike ma ka iwi poʻo nui loa o Triceratops, a ua hōʻike kekahi o ia mau mea i nā hōʻailona o ka loli.
Ma kahi pōʻaiapili nui, hōʻike ikaika nā ʻike o ka dino-blitz he nui nā dinosaur i ʻike ʻia he ʻano pākahi he hoʻokahi wale nō ʻano.
Inā kākoʻo nā haʻawina hou aku i ka hopena o Torosaurus-as-adult-Triceratops, ʻo ia hoʻi, ʻaʻole like ka ʻokoʻa o nā dinosaur o ka Late Cretaceous e like me ka manaʻo o ka poʻe paleontologists. ʻOi aku ka liʻiliʻi o nā ʻano dinosaur, ʻo ia hoʻi, ʻaʻole lākou i maʻalahi i nā loli o ke kaiapuni a/a i ʻole ua emi mua lākou. I kēlā me kēia ʻano, ʻoi aku ka nui o ka make ʻana o nā dinosaur Late Cretaceous ma hope o kahi hanana pōʻino koke i hoʻololi i nā ʻōnaehana aniau a me nā wahi o ka Honua ma mua o kahi hui like ʻole.
