Makarantun Dinosaur masu tashi
A lokacin Mesozoic, nau'ikan dinosaurs da yawa sun mamaye duniya gaba ɗaya, sun zama manyan kasusuwa. Za mu iya haɗa waɗannan dabbobin cikin umarni biyu:
- Ornithischians(Ornitischia): an san su da dinosaurs tare da “kwankwadar tsuntsaye”, saboda reshen balaguron tsarin ƙashin ƙugu ya kasance a cikin shugabanci (zuwa wutsiya), kamar yadda yake faruwa a cikin tsuntsayen yau. Wadannan dinosaurs sun kasance masu ciyayi kuma suna da yawa. Rarraba su ya kasance a duk duniya, amma sun ɓace a kan iyaka tsakanin Cretaceous da Tertiary.
- Saurischians(Sauriyya): sune dinosaurs tare da "kwatangwalo". Reshen mashaya na saurischians yana da daidaitaccen jijiya, kamar yadda yake faruwa a cikin dabbobi masu rarrafe na zamani. Wannan oda ya haɗa da kowane irin dinosaurs mai cin nama har ma da yawancin ciyayi. Kodayake yawancinsu sun lalace a cikin iyakar Cretaceous-Tertiary, kaɗan sun tsira: tsuntsaye ko dinosaur masu tashi.
Shigar da wannan labarin don koyon yadda dinosaurs suka lalace.
Halayen Flying Dinosaurs
Haɓaka ikon jirgi a cikin dinosaurs ya kasance sannu a hankali lokacin da daidaitawa a cikin tsuntsaye na yau ya fito. A cikin tsari na bayyanar lokaci, waɗannan su ne halayen dinosaur masu tashi:
- yatsu uku: Hannaye tare da yatsunsu guda uku kawai masu aiki da ƙashin ƙugu, waɗanda suka fi sauƙi. Waɗannan albarkatun sun fito ne kimanin shekaru miliyan 230 da suka gabata, a cikin ƙaramin yankin Theropoda.
- hannayen riga: godiya ga kashi mai siffar rabin wata. Wanda aka sani Velociraptor yana da wannan sifa, wanda ya ba shi damar farautar farauta da gogewar hannu.
- Fuka -fukai (da ƙari). Wakilan wannan matakin na iya tashi sama kuma wataƙila ma suna jujjuya fikafikansu don saurin tashi.
- kashin coracoid: bayyanar kashin coracoid (haɗe da kafada zuwa ƙashin ƙugu), kashin kashin baya wanda aka haɗe don samar da wutsiyar tsuntsu, ko pygostyle, da ƙafafun prehensile. Dinosaurs da ke da waɗannan halayen sun kasance arboreal kuma suna da fuka -fukai masu ƙarfi don tashi.
- alula kashi: bayyanar alula, kashin da ke sakamakon haɗuwa da yatsun atrophied. Wannan kashi ya inganta motsi a lokacin tashi.
- Short wutsiya, baya da sternum. Waɗannan su ne halayen da suka haifar da tashin tsuntsaye na zamani.
Irin dinosaurs masu tashi
Dinosaurs masu tashi sun haɗa kuma sun haɗa (a cikin wannan yanayin, tsuntsaye) dabbobin da ke cin nama, da kuma nau'ikan dinosaurs iri -iri. Yanzu da kuka san halayen da, sannu -sannu, ya haifar da tsuntsaye, bari mu ga wasu nau'ikan dinosaur masu tashi ko tsoffin tsuntsaye:
Archeopteryx
Yana da nau'in m tsuntsaye wanda ya rayu a lokacin Upper Jurassic, kimanin shekaru miliyan 150 da suka gabata. An dauke su a siffar miƙa mulki tsakanin dinosaurs marasa gudu da tsuntsayen yau. Tsawon su bai wuce rabin mita ba, kuma fikafikan su sun yi tsawo da fikafikai. Duk da haka, an yi imani da cewa su suna iya zamewa kawai kuma suna iya kasancewa masu hawan bishiya.
Iberosomesornis
Daya dinosaur mai tashi wanda ya rayu a lokacin Cretaceous, kimanin shekaru miliyan 125 da suka gabata. Tsawonsa bai wuce santimita 15 ba, yana da ƙafafun prehensile, pygostyle da coracoids. An gano burbushinsa a Spain.
Ichthyornis
Yana ɗaya daga cikin na farko tsuntsaye masu hakora binciken, kuma Charles Darwin ya dauke shi daya daga cikin mafi kyawun hujjojin ka'idar juyin halitta. Waɗannan dinosaurs masu tashi sun rayu shekaru miliyan 90 da suka gabata, kuma sun kasance kusan santimita 43 a cikin fuka -fuki. A waje, sun yi kama da kwatankwacin tekun yau.
Bambanci tsakanin dinosaurs da pterosaurs
Kamar yadda kuke gani, nau'ikan dinosaur masu tashi ba su da alaƙa da abin da kuke tsammani. Wannan saboda manyan dabbobi masu rarrafe daga Mesozoic ba ainihin dinosaur bane amma pterosaurs, amma me yasa? Waɗannan su ne manyan bambance -bambance tsakanin su biyun:
- fikafikan: fuka -fukan pterosaurs sun kasance shimfidadden membranous wanda ya haɗa yatsansa na huɗu da gabobin bayansa. Koyaya, fuka -fukan dinosaur masu tashi ko tsuntsaye sune madaidaitan goshin gabansu, ma'ana suna da ƙashi.
- iyakar: Dinosaurs suna da gabobin jikinsu a ƙarƙashin jikinsu, suna tallafawa cikakken nauyin su kuma suna basu damar kula da tsayayyen matsayi. A halin yanzu, pterosaurs an miƙa ƙafarsu zuwa kowane ɓangaren jiki. Wannan bambancin ya faru ne saboda gaskiyar cewa ƙashin ƙugu yana da bambanci sosai a cikin kowane rukuni.
Nau'in Pterosaurs
Pterosaurs, da aka sani da suna dinosaur masu tashi, a zahiri wani nau'in nau'in dabbobi masu rarrafe wanda ya kasance tare da ainihin dinosaur a lokacin Mesozoic. Kamar yadda aka san iyalai da yawa na pterosaur, za mu duba kawai wasu daga cikin mahimman nau'ikan:
Pterodactyls
Mafi shahararrun nau'ikan dabbobi masu rarrafe sune pterodactyls (Pterodactylus), asalin halittar pterosaurs masu cin nama cewa ciyar a kan kananan dabbobi. Kamar yawancin pterosaurs, pterodactyls suna da wani kumburi a kai wannan wataƙila da'awar jima'i ce.
Quetzalcoatlus

Kai Quetzalcoatlus, mai suna bayan wani abin bauta na Aztec, zai iya kai tsawon fuka -fukansa na mita 10 zuwa 11 kuma mai yiwuwa mafarauta ne. an yi imani cewa sun kasance dacewa da rayuwar duniya da locomotion na huɗu.
Rhamphorhynchus
Ranphorrhine ɗan ƙaramin pterosaur ne, mai kusan ƙafa shida na fuka -fuki. Sunansa yana nufin "huci tare da baki", kuma yana da nasaba da gaskiyar cewa yana da hancin yana ƙarewa da baki tare da hakora a koli. Kodayake mafi kyawun fasalinsa babu shakka doguwar jelarsa, galibi ana nuna ta a cikin sinima.
