ʻO nā dinosaur kekahi o nā ʻano hoihoi loa i ka mōʻaukala o ka ulu ʻana o ke olaola ma ka Honua. Ua kamaʻāina loa mākou a pau i nā dinosaur. Pehea ke ʻano o nā dinosaur, he aha ka mea a nā dinosaur i ʻai ai, pehea i hahai ai nā dinosaur, he aha ke ʻano o ke kaiapuni i noho ai nā dinosaur, a no ke aha i nalowale ai nā dinosaur… Hiki i nā kānaka maʻamau ke wehewehe i nā nīnau like e pili ana i nā dinosaur ma ke ʻano maopopo a kūpono hoʻi. Ua ʻike mua mākou i nā mea he nui e pili ana i nā dinosaur, akā aia kekahi nīnau a ka poʻe he nui i maopopo ʻole ai a noʻonoʻo paha: Pehea ka lōʻihi o ke ola ʻana o nā dinosaur?
Ua manaʻoʻiʻo nā paleontologists i kekahi manawa ʻo ke kumu i ulu nui ai nā dinosaur no ka mea ua ola lākou no ka awelika o 100 a 300 mau makahiki. Eia kekahi, e like me nā crocodiles, he mau holoholona ulu palena ʻole nā dinosaur, e ulu mālie ana a hoʻomau i ko lākou ola. Akā i kēia manawa ua ʻike mākou ʻaʻole kēia ka hihia. Ua ulu koke ka hapa nui o nā dinosaur a make i ka wā ʻōpiopio.
· Pehea e hoʻoholo ai i ke ola o nā dinosaur?
Ma ke ʻano laulā, ua ola nā dinosaur nui i ka lōʻihi. Ua hoʻoholo ʻia ke ola o nā dinosaur ma ke aʻo ʻana i nā mōʻalihaku. Ma ka ʻoki ʻana i nā iwi mōʻalihaku o nā dinosaur a me ka helu ʻana i nā laina ulu, hiki i nā kānaka ʻepekema ke hoʻoholo i ka makahiki o ka dinosaur a laila wānana i ke ola o ka dinosaur. Ua ʻike mākou a pau e hiki ke hoʻoholo ʻia ka makahiki o kahi lāʻau ma ka nānā ʻana i kona mau apo ulu. E like me nā lāʻau, hana pū nā iwi dinosaur i nā "apo ulu" i kēlā me kēia makahiki. I kēlā me kēia makahiki e ulu ana kahi lāʻau, e ulu ana kona kumu i loko o kahi pōʻai, kahi i kapa ʻia he apo makahiki. Pēlā nō hoʻi no nā iwi dinosaur. Hiki i nā kānaka ʻepekema ke hoʻoholo i ka makahiki o nā dinosaur ma ke aʻo ʻana i nā "apo makahiki" o nā mōʻalihaku iwi dinosaur.
Ma o kēia ʻano hana, ua manaʻo nā paleontologists he 10 wale nō makahiki ke ola o ka dinosaur liʻiliʻi ʻo Velociraptor; he 20 mau makahiki ko Triceratops; a ʻo ka haku dinosaur, ʻo Tyrannosaurus rex, he 20 mau makahiki e hiki ai i ka wā makua a make pinepine ma waena o 27 a me 33 mau makahiki. ʻO ke ola o Carcharodontosaurus ma waena o 39 a me 53 mau makahiki; ʻo nā dinosaur ʻāʻī lōʻihi nui me nā mea kanu lau nahele, e like me Brontosaurus lāua ʻo Diplodocus, he 30 a 40 mau makahiki e hiki ai i ka wā makua, no laila hiki iā lākou ke ola a hiki i 70 a 100 mau makahiki.
Me he mea lā ʻokoʻa loa ke ola o nā dinosaur mai ko kākou noʻonoʻo ʻana. Pehea lā e hiki ai i kēlā mau dinosaur kupaianaha ke loaʻa i kēlā mau ola maʻamau? E nīnau paha kekahi mau hoaaloha, he aha nā mea e hoʻopilikia ai i ke ola o nā dinosaur? He aha ke kumu i ola ai nā dinosaur i kekahi mau makahiki wale nō?
· No ke aha i ola ʻole ai nā dinosaur i ka lōʻihi?
ʻO ka mea mua e hoʻopilikia ai i ke ola o nā dinosaur, ʻo ia ka metabolism. Ma keʻano laulā, ʻoi aku ka pōkole o ke ola o nā endotherms me nā metabolism kiʻekiʻe ma mua o nā ectotherms me nā metabolism haʻahaʻa. I ka ʻike ʻana i kēia, e ʻōlelo paha nā hoaaloha he mau reptile nā dinosaur, a he mau holoholona koko anu nā reptile me nā ola lōʻihi. ʻOiaʻiʻo, ua ʻike nā kānaka ʻepekema he mau holoholona koko mahana ka hapa nui o nā dinosaur, no laila ua hoʻemi ke kiʻekiʻe o ka metabolism i ke ola o nā dinosaur.
ʻO ka lua, ua loaʻa i ke kaiapuni kahi hopena make i ke ola o nā dinosaur. I ka wā i ola ai nā dinosaur, ʻoiai ua kūpono ke kaiapuni no nā dinosaur e noho ai, ua ʻinoʻino nō ia i ka hoʻohālikelike ʻia me ka honua i kēia lā: ʻo ka nui o ka oxygen i ka lewa, ka nui o ka sulfur oxide i ka lewa a me ka wai, a me ka nui o ka radiation mai ke ao holoʻokoʻa he ʻokoʻa ia mai kēia lā. ʻO kēlā ʻano ʻinoʻino, me ka hahai holoholona ʻino a me ka hoʻokūkū ma waena o nā dinosaur, ua make nā dinosaur he nui i loko o kahi manawa pōkole.
Ma keʻano holoʻokoʻa, ʻaʻole lōʻihi ke ola o nā dinosaur e like me ka manaʻo o nā mea a pau. Pehea lā i hiki ai i kēlā ʻano ola maʻamau ke ʻae i nā dinosaur e lilo i mau aliʻi o ka Mesozoic Era, e noho aliʻi ana ma ka honua no kahi o 140 miliona mau makahiki? Pono kēia i ka noiʻi hou aku e nā paleontologists.
