名稱 菊石結核化石Name Dactylioceras commune (mounted) Ammonite Fossil地質年代 下侏羅紀Geological AgeLower Jurassic描述 菊石化石是一群已經滅絕的海洋生物，生存於中奧陶世至晚白堊世，因它的表面通常具有類似菊花的線紋而得名。菊石的殼體是一個以碳酸鈣為主要成分的錐形管。殼管的始端細小，通常呈球形或桶形，稱為胎殼。絕大多數菊石的殼體以胎殼為中心在一個平面內旋卷，少數殼體呈直殼、螺卷或其他不規則形狀。Description Dactylioceras was a widespread genus of ammonites from the Lower Jurassic period, approximately 180 million years ago. Dactylioceras are generally small, averaging 65 millimetres (2.6 in) in diameter. They have a strong, ribbed shell. The ribs are slightly inclined forward, running over the outer edge, and either simple or forking at outer end.地點 約克夏，英國Location Whitby, Yorkshire.

名稱 恐龍骨化石 Name Dinosaur Bone Fossil地質年代 白堊紀Geological Age Cretaceous描述 恐龍骨化石很容易與其他岩石區分開。骨骼的細胞結構通常是可見的，如孔狀的蜂窩。一些恐龍骨骼用於製作珠寶。它需要高拋光度，細胞結構的圖案也增加了美感。恐龍或生活在中生代的侏羅紀和白堊紀。科學家將恐龍分為兩類：Saurischia（爬行動物的臀部）和Ornithischia（鳥的臀部）。一些恐龍有羽毛。大多數古生物學家認為，恐龍是當今鳥類的祖先。Description Dinosaur bone fossil is easily distinguished from other rocks. The cell structure of the bone is usually visible. This shows up as a honeycomb of holes. Some dinosaur bone is used in making jewelry. It takes a high polish and the patterns of the cell structure add to the beauty of the stone. Dinosaurs or lived during the Jurassic and Cretaceous Periods of the Mesozoic era. Scientists divide dinosaurs into two groups: Saurischia (reptile hipped) and…

名稱 對筆石屬化石 Name Didymograptus Graptolite fossil地質年代 奧陶紀Geological Age Ordovician描述 筆石綱動物是一類已絕種的海洋群體動物，普遍生活在古生代的海洋，是古生代的標準化石。它們在寒武紀時代出現， 在奧陶紀時代分佈最廣、最繁盛 ，但在石炭紀卻未能逃過絕滅的命運。筆石化石通常保存於泥岩中，常呈炭質薄膜，好像用鉛筆書寫在岩石上的痕跡，因此被命名為「筆石」。筆石綱動物是群體生活的動物。它具有一條好像骨骼的纖維，這條「骨骼」連貫著很多個體，稱為「胎管」，它們串連起來組成一組「苞管」，發育成群體；苞管亦可再獨立個別藏有游動孢子的囊。群體筆石的苞管數目不一，囊的排序亦不一樣，所以古生物學家就利用苞管的數目和囊的排序來鑑定不同種類的筆石化石。筆石化石可分為兩個目，第一目是營固生活的樹形筆石目；第二類是漂游生活的正筆石目。Description Didymograptus is an extinct genus of graptolites with four rows of cups. They lived during the Middle Ordovician, to Late Ordovician. Fossil graptolites are thin, often shiny, markings on rock surfaces that look like pencil marks, and their name comes from the Greek for ‘writing in the rocks’. Graptolites are the remains of intricate colonies, some of which accommodated up to 5000 individual animals; these individuals lived in a skeleton of collagen, similar to…

名稱 直角石化石Name Orthoceras Fossil地質年代  /Geological Age  /描述 直角石是一屬已滅絕的鸚鵡螺類。它的殼形為細長的柱狀椎體，稱爲“直角石式殼”，由間距緊密的凹凸腔室組成。中央是住室，其次是連接各腔的連室細管。殼表面有很多幼細的細褶襞。多種其他相似的物種都被分類在米契林角石屬中。雖然直角石的外殼像鸚鵡螺，但卻應該更爲接近蛸亞綱。直角石化石分佈於歐洲地區，可追溯至奧陶紀至三疊紀。Description Orthoceras is a genus of extinct nautiloid cephalopod. These are slender, elongate shells with the middle of the body chamber transversely constricted, and a subcentral orthochoanitic siphuncle. The surface is ornamented by a network of fine lirae. Many other very similar species are included under the genus Michelinoceras. Orthocera Fossil’s distribution is in Europe. and it can be traced back to Middle Ordovician.  地點  /Location / 參考 Reference  編者 由 3E (2) 陳凱進 於4/6/2018編寫 _________ 於17/1/18最後編改  Editor Created…

名稱 海百合化石Name Crinoid Fossil地質年代 上石炭紀Geological Age Upper Carboniferous描述 海百合是一種始見於奧陶紀的棘皮動物，生活於海裏，具多條腕足，身體呈花狀，表面有石灰質的殼。海百合具有形如植物的外形，及變化多端的顏色，有如一朵朵在海底綻放的彩色煙火。由於牠們的外形有如羊齒植物或百合花，因此有”海羊齒”及”海百合的稱號。 海百合綱動物與其他棘皮動物最大的不同是牠們的口是朝上的，利用羽毛狀的腕及”羽枝”捕捉海水中的有機顆粒及浮游生物，再由腕中央的步帶溝將食物顆粒送至口中。 這大型海百合莖化石標本長約5厘米-7厘米，直徑約1.5厘米，在標本上仍可以看到節段。 請注意，這些標本取自30年前的舊庫存。Description Crinoids are marine animals that make up the class Crinoidea, one of the classes of the phylum Echinodermata, which are also called the lily of the sea.
