Tansaaniya waxaa laga helay xayawaan qadiimi ah oo 240 milyan sano ka hor ku noolaa
Saynisyahannadu waxay ku guuleysteen inay ogaadaan nooc cusub oo xayawaan qadiimi ah oo dhirta cuna, kaas oo ku noolaa qiyaastii 240 milyan oo sano ka hor, halkaas oo horey looga helay oo kaliya Koonfurta Ameerika.
Nooc cusub oo xayawaan qadiimi ah oo la ogaaday
Daraasadda waxaa hoggaaminayay khubaro ka socda Jaamacadda Bristol, kuwaas oo si faahfaahsan u baaray haraadiga noolahaas oo lagu hayay Matxafka Taariikhda Dabiiciga ah ee London. Waxayna ogaadeen inay ka tirsanaayeen nooc xayawaan dhirta cuna ah oo loo yaqanno dicynodont.
Si gaar ah, haraadigu wuxuu ahaa midka Dinodontosaurus, oo ah nooc xayawaan xilligii hore jiray, kaas oo horey looga helay oo kaliya Koonfurta Ameerika. Baaritaan dheeraad ah ayaa muujiyay in haraadiga laga helay Tanzania uu ka tirsanaa nooc aan hore loo aqoon, kaas oo cilmi-baarayaashu u bixiyeen Dinodontosaurus isiyavamanda.
Muhiimadda daahfurkan oo ka caawinaya cilmi-baarista
Khubaradu waxay leeyihiin daahfurku waa muhiim sababtoo ah dhagaxyada laga helay Dindontosaurus ayaa sidoo kale soo saaray qaar ka mid ah haraadigii ugu da'da weynaa ee loo malaynayo inay yihiin dinosaurs. Hadda oo Dindontosaurus laga helay Tansaaniya iyo Koonfurta Ameerika, saynisyahannadu waxay awoodeen inay go'aamiyaan in dhagaxyada ay ku jiraan haraadiyadaan ay qiyaastii isku da' yihiin.
Hugaamiyaha qoraalka daraasadda, Hady George, oo ka tirsan Jaamacadda Bristol, ayaa sharraxay: 'Tani waxay gacan ka geysaneysaa xaqiijinta in haraadigii dinosaur-ka ee ugu da'da weynaa ee laga soo sheegay Tansaaniya laga yaabo inaysan ka weynayn kuwa ka yimid Koonfurta Ameerika, sidaas darteedna ay hagaajinayso fahamkeenna ku saabsan jadwalka isbeddelka dinosaur-ka.'
Dib-u-qiimeynta goorta iyo meesha dinosaur-ku ka soo baxeen
Kooxdu waxay intaas ku dartay in, natiijada daahfurka awgeed, saynisyahannadu ay u baahan karaan inay dib u qiimeeyaan goorta iyo meesha dinosaur-ku markii ugu horreysay ka soo baxeen. Tani waxay ka dhigan tahay in xogta cusub ee laga helay Tansaaniya ay noqon karto mid muhiim u ah fahamka taariikhda xayawaannada qadiimiga ah ee dunida.
Helitaanka Dinodontosaurus isiyavamanda wuxuu muujinayaa in baaritaannada cusub ee saynisyadeed ay noqon karaan kuwo ka beddelaya fahamka hore ee taariikhda xayawaannada qadiimiga ah, gaar ahaan kuwa ku noolaa Bariga Afrika.
Scientists have identified a previously unknown herbivorous dinosaur species, Dinodontosaurus isiyavamanda, in Tanzania, dating back approximately 240 million years. The find, led by researchers from the University of Bristol, challenges existing timelines for the earliest dinosaurs and may require a global re-evaluation of when these creatures first emerged on Earth.
A New Species Challenges Ancient Records
Fossils of the newly named Dinodontosaurus isiyavamanda were unearthed in Tanzania, a country in East Africa. Prior to this discovery, fossils of the Dinodontosaurus genus had only been found in South America, making this find particularly significant for paleontologists worldwide.
The animal was a herbivore, meaning it fed on plants. Its remains were collected over a span of 60 years from Tanzanian soil, and the fossils were later studied at the Natural History Museum in London, where experts confirmed their unique classification.
Implications for the Origins of Dinosaurs
The discovery suggests that the oldest dinosaur fossils from Tanzania may not be older than those from South America. This finding could help scientists better understand when and where dinosaurs first appeared on Earth, potentially reshaping the global narrative of dinosaur evolution.
Hady George, the lead author of the research from the University of Bristol, stated that the discovery aids in confirming that the oldest dinosaur fossils from Tanzania may not exceed those from South America, thereby improving understanding of the timeline of dinosaur change.
A Call for Scientific Re-evaluation
Due to the significance of the find, experts have called for a re-evaluation of when and where dinosaurs first emerged. The fossils, which also contain some of the oldest specimens believed to be dinosaurs, are now being examined to determine their precise age and relationship to other known species.
The research team emphasized that this discovery is a milestone in paleontology, as it may alter the established timeline of dinosaur origins and distribution across continents, prompting further global collaboration in fossil research.
