# Ososayensi Babunquma Kanjani Ubudala Bamafosili Amadayinaso?

> Ososayensi bavame ukunquma ubudala bedayinaso ngokuthola ubudala bamadwala alizungezile. Ukuhleleka kwezingqimba kunikeza ukulandelana kwesikhathi; amaminerali afanele anganikeza ubudala obuyisibalo. Indlela ye-carbon-14 iwusizo ezinsaleleni zakamuva kakhulu, kodwa ibanga layo lesikhathi lifushane kakhulu kumadayinaso angewona izinyoni.

## Impendulo emfushane

Ososayensi bavame ukunquma ubudala bedayinaso ngokuthola ubudala bamadwala alizungezile. Ukuhleleka kwezingqimba kunikeza ukulandelana kwesikhathi; amaminerali afanele anganikeza ubudala obuyisibalo. Indlela ye-carbon-14 iwusizo ezinsaleleni zakamuva kakhulu, kodwa ibanga layo lesikhathi lifushane kakhulu kumadayinaso angewona izinyoni.

## Amaqiniso ngamafuphi

- Ubudala obuqhathanisiwe: Ukuba ludala noma lwakamuva kunolunye ungqimba
- Ubudala obuyisibalo: Isilinganiso sobudala esinezinga lokungaqiniseki
- Umehluko obalulekile: Ubudala beminerali abubi ngokuzenzakalela ubudala befosili

## Qala ngokunquma ukulandelana

Ezingqimbeni zezinsalela ezingaphazamisekanga, ungqimba olungezansi lwanqwabelana ngaphambi kolungaphezulu. Amadwala angempela avele obala adinga ukuhlolwa ngokucophelela: ukugobeka, ukuqhekeka nokuguguleka kungaphazamisa noma kuguqule ukulandelana. Izazi zesayensi yomhlaba zakha kabusha lowo mlando ngaphambi kokuchaza indawo yefosili.

Amafosili anezimpawu ezihlukile angasiza nasekuxhumaniseni izingqimba zezindawo ezihlukene. Umhlahlandlela we-Smithsonian wokunquma ubudala uchaza kokubili ubudala obuqhathanisiwe nokusetshenziswa kwamafosili ayizinkomba. Ukuxhumanisa kuhlanganisa amarekhodi; akusho ukuthi amadwala amabili abukeka efana akheka ngosuku olufanayo ncamashi.

## Bese ufuna iwashi leminerali elifanele

Amanye ama-isotope angazinzile aguquka ngokubola kwemisebe ngamazinga alinganisekayo. Uma umlando weminerali uqondakala futhi ukushintshana kwezinto nendawo engaphandle kuye kwahlala kulinganiselwe ngokwanele, isilinganiso sama-isotope okuqala nalawo akhiqizwe ukubola singasiza ukuthola ukuthi iwashi laqala nini. Amaminerali nezindlela ezihlukene zifanele amabanga obudala ahlukene.

Enzikeni enamafosili amadayinaso, izinto ezivela ezintabamlilweni zingaba wusizo kakhulu. Ungqimba lomlotha olungaphezulu noma olungezansi kwefosili, uma ubudala balo bulinganisiwe, lunganciphisa ibanga lobudala befosili. Isampula elilinganisiwe kufanele lihlobane ngempela nesenzakalo esichazwayo; uhlamvu oludala kakhulu olugezekele enzikeni yakamuva lungaphendula omunye umbuzo.

## Ibanga lobudala elilula

Cabanga ngongqimba lwefosili oluphakathi kwezingqimba ezimbili zomlotha. Kulesi sibonelo sokufundisa, umlotha ongezansi uneminyaka ecishe ibe yizigidi ezingu-102, kanti ongaphezulu uneminyaka ecishe ibe yizigidi ezingu-100. Uma izingqimba zisalandelana ngendlela yokuqala futhi ifosili lingakhishwanga edwaleni elidala laphinde lafakwa lapha, lagqibeka phakathi kwalezo zikhathi. Lezi izinombolo eziyindilinga eziqanjelwe ukubonisa indlela yokucabanga, hhayi izilinganiso zesampula langempela.

Isibonelo sokulandelana kwezingqimba, esakamuva siphezulu

| Ungqimba | Ubudala besibonelo | Olusitshela khona |
| --- | --- | --- |
| Umlotha ongaphezulu | Cishe iminyaka eyizigidi ezingu-100 | Ungqimba lwefosili lwase lukhona |
| Izinsalela ezinedayinaso | Phakathi kwezingqimba ezinobudala obulinganisiwe | Ukugqibeka kwenzeka ngaphakathi kwaleli banga |
| Umlotha ongezansi | Cishe iminyaka eyizigidi ezingu-102 | Ungqimba lwefosili lwanqwabelana kamuva |

## Kungani indlela yekhabhoni ingabunqumi ubudala be-T. rex?

I-carbon-14 ithatha cishe iminyaka engu-5,730 ukuze ingxenye yayo esele yehle ibe uhhafu. Ngemva kwezikhathi eziningi ezinjalo, kusala okuncane kakhulu kwe-carbon-14 yokuqala ukuze isebenze njengewashi eliwusizo. Ibanga elisebenzisekayo lingamashumi ezinkulungwane zeminyaka, hhayi amashumi ezigidi asihlukanisa namadayinaso angewona izinyoni. Isilinganiso esincane esivela efosilini lasendulo singase siveze ukungcola okuvela ngaphandle noma isignali engemuva; asibi ngokuzenzakalela ubudala besilwane. Indlela yokunquma ubudala nemingcele yayo ibaluleke njengomphumela waselabhorethri.

## Funda ubudala kanye nobufakazi

Isihloko sezindaba singasonga ubudala sithi “iminyaka eyizigidi ezingu-150”. Iphepha locwaningo kufanele lichaze ukuthi yini elinganisiwe, amasampula avelaphi nokuthi ukungaqiniseki kungakanani. Ibanga linikeza ulwazi oluwusizo, alisona isivumo sokuthi akekho owazi lutho.

Endaweni yase-Connecticut i-Dinosaur Trackway, ukuxhumanisa izingqimba zamadwala nezendlalelo ze-basalt ezihambisana nazo kusiza ukubeka imikhondo eduze kokuqala kwe-Jurassic, eminyakeni ecishe ibe yizigidi ezingu-200 edlule. Incazelo ye-National Park Service ibonisa ukuthi kungani amadwala azungezile eyingxenye yobufakazi. Sebenzisa umhlahlandlela wethu wezinkathi ukuze ubone umugqa wesikhathi obanzi, bese usebenzisa umhlahlandlela wokwakheka kwamafosili ukuqonda okwenzeka ngaphambi kokutholakala.

## Imibuzo nezimpendulo

### Ososayensi bangalinganisa ubudala bethambo uqobo?

Ngezinye izikhathi izinto zefosili zifanele izindlela ezithile zokulinganisa ubudala, kodwa umphumela kufanele uchazwe ngokuhlobana nokwakheka kwamaminerali nezinguquko zakamuva. Ubudala bamadayinaso amaningi bunqunyelwa ibanga kusetshenziswa amadwala ahambisana nawo.
