But there is another possibility as well , said marknorell , curator of paleontology at the american museum of naturalhistory : it is entirely possible that juravenator did have feathers , butthey simply failed to fossilize . feathers are really just difficult things to preserve , norellsaid 美國自然歷史博物館的古生物學家馬克諾萊爾還提出了另外一種說法,即完全有可能juravenator的確長有羽毛,但是這些羽毛卻沒能形成化石。
You will drive past the great divide watershed of the american continent to arrive at mammoth hot springs to view the multi - colored lava flow from extinct volcanoes , examine fossilized trees , and catch the glimmer of beautiful lakes in the secluded woods 穿越美國大陸的分水嶺,到達公園最北的mammoth hot springs ,五顏六色的梯田,溫泉及滾燙的熔巖,石化的古木,碳化的火山口,林間的小湖,泛上裊裊的輕煙,宛如神話世界。
Continue with your tour of the park this morning to arrive at the mammoth hot springs to view the multi - colored lava flow from extinct volcanoes . examine fossilized trees , and catch the glimmer of beautiful lake in the secluded woods . in the afternoon , proceed to gillette 上午繼續(xù)游覽黃石公園,到達公園最北的mammoth hot springs ,五顏六色的梯田溫泉及滾熱的熔巖石化的古木,碳化的火山口,林間的小湖,泛上裊裊的輕煙,宛如神話世界。
During the pleistocene epoch the area that is now tso - chen was repeatedly covered and uncovered by the sea , and the fossilized remains of many organisms were preserved in the sediments that were laid down . today , after each heavy rain the bed of tsailiao creek is left covered with large numbers of fossils 左鎮(zhèn)的菜寮溪流域,由于更新世時為海親海退相互間發(fā)生的不安定環(huán)境,造成大量死亡的生物形成化石沉積,每逢豪雨沖刷,菜寮溪河床上即散布大量的古生物化石。
In the third part , great importance is attached to the inadaptability between secondary vocational education and industrial restructuring , which reflects in the following aspects : single training objective ; inappropriate course design ; out - dated auricular system ; old teaching approaches and methods ; single evaluating mode ; fossilized teaching system ; weak foundation for combination between schools and enterprises ; inadaptability between teaching staff and industrial structure 第三部分著重分析了黔江中等職業(yè)學校教育與工業(yè)結構調整的不相適應性,主要表現在:培養(yǎng)目標單一;專業(yè)設置不合理;課程體系陳舊;教學手段和方法滯后;評價方式單一;教學體制不靈活;培養(yǎng)途徑單一,校企聯合薄弱;教師隊伍結構與工業(yè)結構不適應。
