Fresnosaurus

Magacu wuxuu ka dhigan yahay: “Fresno lizard, loogu magac daray Fresno County ee California”1

Cunay: HilibPlesiosaursCretaceous-kii dambeSi farsamo ahaan ma aha dinosaur

Fresnosaurus wuxuu ahaa xamaarato weyn oo dabaasha ah oo leh qoorta aad u dheer iyo baalal halkii ay ka ahaan lahaayeen lugaha. Wuxuu ku noolaa badda u dhow California intii lagu jiray waqtigii dinosaurs-ka, laakiin ma ahayn dinosaur. Waxa uu u badan tahay in uu qoortiisa dheer u isticmaali jiray in uu si qarsoodi ah ugu soo dhowaado kalluunka iyo xayawaannada kale ee yaryar ee badda.1 3

Xaqiiqo xiiso leh: xayawaankan badda ku nool wuxuu dabaalanayay halka dinos-ku ay dhulka ku socdeen. Qof walba wuxuu ugu yeeraa dinos, laakiin waxay ahaayeen qayb kale oo ka mid ah xayawaanka gurguurta.

Xaqiiqooyin xiiso leh

Fresnosaurus wuxuu noolaa qiyaastii 70 ilaa 66 milyan oo sano ka hor, xilligii uu dhammaanayay Da'dii Dinosaurs-ka.1

Fossil-ka kaliya ee la yaqaan wuxuu ka yimid xayawaan yar, markaa saynisyahannadu waxay u maleynayaan in dadka waaweyn ay ka weynaan karaan xitaa 9 m (30 feet).2

Magaciisu wuxuu sharfayaa Fresno County, magaca noocana 'drescheri' wuxuu sharfayaa Arthur Drescher, oo u badan tahay inuu gacan ka geystay helitaanka fossil-ka.1

Fresnosaurus wuxuu ka tirsanaa koox la yiraahdo elasmosaurids, oo caan ku ah qoortooda aadka u dheer iyo baalasha u eg kuwa doonyaha.1 3

Fossil-ku wuxuu ka kooban yahay lafo ay ka mid yihiin coracoids (lafaha garabka), humerus (lafaha gacanta sare), pelvic girdle, iyo femora (lafaha bowdada), laakiin wax madax ah lama helin.2

Saynisyahannadu dhawaan waxay ogaadeen in qaar ka mid ah lafaha dheeraadka ah ee lagu calaamadeeyay Fresnosaurus ay dhab ahaantii ka tirsanaan karaan plesiosaur kale oo la xiriira oo la yiraahdo aristonectine.2

Sawirka Fresnosaurus oo uu sameeyay AI — Sawir uu sameeyay AI oo muujinaya sida Fresnosaurus u ekaan karay, oo uu kombuyuutarku ka sameeyay waxa ay saynisyahannadu yaqaaniin. Waa qiyaas: xayawaanka dhabta ah waxaa laga yaabaa inuu u ekaa si ka duwan, qofna ma garanayo midabadiisa dhabta ah.

Rex wuxuu kaliya ka jawaabaa su'aalaha ku saabsan boggan. 10 su'aalood bishii.

Rex waa AI wuxuuna samayn karaa khaladaad. Wuxuu ku shaqeeyaa server-yada EU-da, su'aalahana marnaba lama kaydiyo. Weligaa ha qorin magacaaga ama waxyaabo kale oo shakhsi ah.

Burinta khuraafaadka

Khuraafaad: Dadka qaar waxay u maleynayaan in Fresnosaurus uu ahaa dinosaur sababtoo ah wuxuu la noolaa dinosaurs-ka waxaana inta badan lagu muujiyaa buugaagta dinosaurs-ka.

Runta: Fresnosaurus wuxuu ahaa plesiosaur, xamaarato badda ah, ee ma ahayn dinosaur. Dinosaurs-ku waxay ku noolaayeen dhulka waxayna lahaayeen qaabab jidh oo kala duwan.1 3

Khubarada dino

Magaca sayniska: Fresnosaurus
Waxaa magacaabay: Welles 19433
Koox: Plesiosaurs
Qoyska / kooxda: Elasmosauridae3
Kala soocidda: Plesiosauria > Elasmosauridae > Sauropterygia3
Xilligii dhagaxyada: 72 ilaa 66 milyan oo sano (Maastrichtian)3
Dhagaxyada: Moreno3
Waddamada: USA3
Diiwaanka fossil-ka: 1 oo ku jira Paleobiology Database3
Daahfurka: Fresnosaurus waxaa markii ugu horreysay sharraxay Samuel Paul Welles sanadkii 1943, iyadoo lagu saleynayo fossil laga helay Moreno Formation ee California. Fossil-ka waxaa markii hore lagu hayay Machadka Teknolojiyadda ee California, haddana wuxuu ku yaallaa Matxafka Taariikhda Dabiiciga ah ee Los Angeles County.1 2
Wali waa la isku khilaafsan yahay: Saynisyahannadu weli way doodayaan in Fresnosaurus uu yahay nooc sax ah oo gooni ah ama haddii uu la mid noqon karo elasmosaurid kale, sababtoo ah fossil-ka kaliya ee la hayo waa mid aan dhammaystirnayn oo ka yimid xayawaan yar.2

Xaqiiqo kasta oo boggan ku taal waxay leedahay lambar tilmaamaya halka ay ka timid. Haddii aan wax khaldnay, raali ahow, waxaan nahay taageerayaasha dino, ma nihin joornaal saynis. Noo sheeg [email protected] waana hagaajin doonnaa.

Rex wuu gaajaysan yahay! Dino Wiki waa mashruuc aabbe u sameeyay wiilkiisa dino-jecel, bilaash ah oo aan lahayn xayeysiis iyo qalab raad-raac. Dadka waaweyn waxay Rex siin karaan cunto fudud si ay uga caawiyaan inuu khadka ku sii jiro.Quudi Rex
