Riojasaurus
Riojasaurus wuxuu ahaa dinosaur weyn oo dhirta cuna, leh qoorta dheer iyo jidh culus. Wuxuu noolaa intii lagu jiray xilligii Triassic-ga dambe meesha hadda loo yaqaan Argentina. Waxa uu u badnaa inuu si tartiib ah ugu socdo afar lugood, isagoo caleemaha ku calaalinaya ilkahiisa caleen-u-samaysan.1

Xaqiiqooyin xiiso leh
Riojasaurus wuxuu lahaa lafo lugood oo aad u cufan oo waaweyn, taas oo ka dhigaysa mid culus oo adag marka loo eego sauropodomorph-kii hore.1
Si ka duwan qaraabadiisa badankood, Riojasaurus wuxuu lahaa afar lafood oo miskaha ah halkii ay ka ahaan lahaayeen saddex, taas oo ka caawisay inuu qaado miisaankiisa.1
Lafaha qoortiisu waxay ahaayeen kuwo ka dhaadheer kuwa kale ee sauropodomorph-ka ah ee laga helay isla goobta, taas oo ka dhigaysa qoortiisa mid aad u dheer.1
Lafaha Riojasaurus ee ugu horreeyay ee la helay ma lahayn madax. Madax si fiican loo xafiday ayaa markii dambe la helay sannadkii 1987 waxaana la sharraxay sannadkii 1995.1
Saynisyahannada qaarkood waxay u malaynayaan in Riojasaurus uu firfircoonaan karay waqtiyo gaagaaban maalintii iyo habeenkii, taas oo ku salaysan qaabka lafaha indhihiisa.1
Riojasaurus waa dinosaur-ka kaliya ee riojasaurid ee laga yaqaan Koonfurta Ameerika, waxaana laga yaabaa inuu xidhiidh dhow la leeyahay Melanorosaurus oo laga helay koonfurta Afrika.1
Lugahiisa hore iyo kuwa dambe waxay ahaayeen kuwo dherer ahaan isku mid ah, taas oo ah calaamad muujinaysa inuu ku socday afar lugood oo uusan awoodin inuu ku istaago lugahiisa dambe.1
Su'aalaha ugu badan ee ku saabsan Riojasaurus
?Intee in le'eg ayuu ahaa Riojasaurus?
Riojasaurus wuxuu ahaa ilaa 6.6 mitir (21.7 cag) oo dherer ah, miisaankiisuna wuxuu ahaa ilaa 800 kiilogaraam (1,764 rodol). Qaar ka mid ah xoolaha waaweyn ayaa laga yaabaa inay gaareen 10 mitir (32.8 cag) oo dherer ah iyo miisaan dhan 3 tan (3.3 tan oo gaaban).1
?What did Riojasaurus eat?,Maxay cuni jirtay Riojasaurus?
Riojasaurus was a herbivore that ate plants. Its leaf-shaped, serrated teeth were used for grazing on soft vegetation like gymnosperms, and it may have swallowed stones (gastroliths) to help grind food in its stomach.,Riojasaurus waxay ahayd xayawaan dhirta cuna. Ilkaheeda caleen-u-ekaanta ah ee fiiqan ayaa loo isticmaali jiray inay ku daaqdo dhirta jilicsan sida gymnosperms, waxaana laga yaabaa inay liqi jirtay dhagaxyo (gastroliths) si ay uga caawiso shiididda cuntada caloosheeda.13
?Could Riojasaurus walk on two legs?,Riojasaurus ma ku socon kartay laba lugood?
No, Riojasaurus probably walked on all four legs. Its front and hind limbs were nearly the same length, and its leg bones were dense and massive, suggesting it moved slowly on all fours and could not rear up on its back legs.,Maya, Riojasaurus waxay u badan tahay inay ku socon jirtay afar lugood. Lugaha hore iyo kuwa dambe waxay ahaayeen kuwo dhererkoodu isku dhow yahay, lafaha lugaha ayaana ahaa kuwo culus oo adag, taas oo muujinaysa inay si tartiib ah ugu socon jirtay afarta lugood oo aysan awoodin inay ku istaagto lugaha dambe.1
?When did Riojasaurus live?,Goorma ayay noolayd Riojasaurus?
Riojasaurus wuxuu noolaa xilligii Late Triassic, qiyaastii 225 ilaa 213 milyan oo sano ka hor. Hadhagiisa waxaa laga helay Los Colorados Formation oo ku taal Argentina.1
?Is Riojasaurus a dinosaur?,Riojasaurus ma tahay dinosaur?
Yes, Riojasaurus is a dinosaur. It is a herbivorous sauropodomorph dinosaur from the Late Triassic of Argentina.,Haa, Riojasaurus waa dinosaur. Waa dinosaur dhirta cuna oo ka tirsan sauropodomorph, waxayna noolayd xilligii Late Triassic ee dalka Argentina.1
?Did Riojasaurus have feathers?,Riojasaurus ma lahayd baalal?
No, there is no evidence that Riojasaurus had feathers. Its fossils show only scales and bones, and it is not known to have any feather-like structures.,Maya, ma jirto caddayn muujinaysa in Riojasaurus ay lahayd baalal. Lafaha iyo haraaga laga helay waxay muujinayaan oo kaliya qolof iyo lafo, lamana oga inay lahayd wax baal u eg.1

- Wali waa la isku khilaafsan yahay
- Saynisyahannadu way isku khilaafsan yihiin in Riojasaurus uu si buuxda ugu socon jiray afar lugood ama uu mararka qaarkood ku socon jiray laba lugood. Lafaha gacanta iyo garabka waxay soo jeedinayaan inuu awoodi karay inuu u dhaqaaqo siyaabo kala duwan.1
