29-恐龍紹介(振元龍)Zhenyuanlong      Tsín-guân-liông,華語叫做「振元龍」,是中國遼寧的一位作穡人發現的,尾仔共交予古生物博物館研究,佇2015年發表,號名叫振元龍,是欲紀念彼个博物館館長孫振元先生。振元龍應該是生活佇1億1300萬年前的白堊紀早期。      In身長欲倚2米,身軀頂足濟所在攏有羽毛,可能佮這馬的í-miuh鳥(鴯鶓)足仝形。目前發現的後跤化石頂懸,無保留羽毛的痕跡,猶毋過彼塊石枋嘛無保存身軀的羽毛,所擺凡勢是化石保存過程中,後跤羽毛的痕跡無保留著,科學家猶未排除in後跤有羽毛的可能。振元龍前跤足短,猶毋過翼仔的羽毛誠長,翼仔佮現此時的鴟鴞足仝形。不而過振元龍的體重有20公斤,是鴟鴞的兩倍,所擺就算in的翼仔看起來誠現代,受著體重的限制,in應該是飛袂起來。若按呢,in的翼仔可能是用來展威弄颺、威脅對手、抑是是欲唌母的ê振元龍,佮孔雀開屏的作用仝款,抑者是保暖、孵卵咧用。      雖罔科學家進前就捌發現閣較大隻的有羽毛的恐龍,毋過攏毋是像振元龍這種佮現代鳥仔足仝形的羽毛,這个發現顯示大型有現代化羽毛結構的恐龍,可能比科學家本底所想的閣較濟。科學家認為in可能佮小盜龍有相siāng的祖先,但是佇演化的過程中,愈用著的會愈發達,愈無用著的就會愈退化,in tsua̋n沓沓仔變做袂飛的恐龍矣!      今仔日的「振元龍」就講到遮,感謝逐家的收聽。 - - - - - - - - - - - - - - -  展威 tián-ui 弄颺 lāng-iānn 燒烙 sio-lō - - - - - - - - - - - - - - - FB迷眾頁:https://reurl.cc/70A5mQ 留言告訴我你對這一集的想法: https://open.firstory.me/user/clohik9vc0vuq01s15xufcp5w/comments Powered by Firstory Hosting
