The second film of Jassic Park, feather, may have evolved than once in dinosas: it is entirely possible that javena did have feathers, which appeared on sister species at different times and places, or that this javena fossil seems to have been a young one, gwing feathers after hood, or losing feathers Mark Norrell, cator of paleontolo, Ican Museum of natal history NORELL said that feathers are part of the year, but there is another possibility, but they just failed to feather fossilize. _Feathers are really hard to preserve. Paleontologists hope Javenator can follow suit.
But this kind of animal has only a all piece of skin, the tail shows no sis of feathers, and the skin does not have the typical hair follicles of feathered dinosas In support of his hypothesis, PE Norrell said he pointed out that sral fossils of the oldest known bird, Archaeopteryx, have many possible explanations, and julavina's naked feathers may have been lost. Two paleontologists pointed out in a study published on Thsday that the million year old fossil was a carnivous juvenile dinosa about 1 / 2 foot long, which scientists named Javenator, becse it was found in the Jassic mountains, descbed the fossil's close relatives with Ursula golich of the University of Munich in the jonal Nate on Thsday. He and Ursula B.
gotch descbed the life of the fossil in the jonal Nate on Thsday, which appeared to threaten a young woman on the beach at the start of lost world Chiappe said paleontologists beli javentors' closest relative may be a feathered dinosa fm China. Sinosaoptex, director of the dinosa Research Institute at the Los Angeles County Museum of natal history, said the fossil's well preserved bone structe clearly showed that it was a feathered relative of the dinosa family One well preserved treeA fossil in southern Germany raises questions about how feathers evolved fm dinosas to birds.

《侏罗纪公园》第二部《羽毛》可能在恐龙身上进化了不止一次：完全有可能朱拉文纳确实有羽毛，在不同时间和地点出现在姐妹物种身上，也有可能这具朱拉文纳化石，看起来是个幼年，成年后才长出羽毛，或者失去了羽自然历史博物馆（Amecan Museum of Natal History）古生物学馆长马克·诺雷尔（Mark Norell）说，羽毛是xx年中一部分，但也有另一种可能，但它们只是未能将羽毛化石化，"羽毛确实是很难保存东西，古生物学家希望Javenator也能效仿，但这类动物身上只有一小块皮肤尾巴没有显示出羽毛迹象，皮肤也没有羽毛恐龙典型毛囊，斯·奇亚佩·诺雷尔说，为了支持他假设，他指出，已知最古老鸟类始祖鸟几块化石有许多可能解释，朱拉文纳体羽毛可能已经丢失两位古生物学家在周四发表一份研究报告中指出，这具百万年前化石是一种约1/2英尺长食肉幼年恐龙，科学家将其命名为Javenator，因为它是在侏罗山脉发现他和慕尼黑大学乌苏拉·戈利奇在上周四出版《自然》杂志上描述了这具化石近亲，他和乌苏拉·B·戈里奇在上周四《自然》杂志上描述了这具化石生活，它看起来与《迷失世界》开场时在海滩上威胁一个年轻女孩飞奔掠食者相似，它有着典型鳞状恐龙皮肤，Chiappe说古生物学家认为Javenators最接近亲属可能是来自一种全羽毛恐龙，洛杉矶县自然历史博物馆恐龙研究所所长Sinosaoptex说，化石保存得非常好骨骼结构清楚地表明它是恐龙家族中有羽毛亲属之一德国南部保存完好treeA化石引发了人们对羽毛是如何从恐龙进化到鸟类质疑。
