名稱 菊螺化石 Name Ammolite 地質年代 / Geological Age / 描述 菊石是一群已經滅絕的海洋生物總稱，隸屬於菊石亞綱。牠們約在志留紀晚期至泥盆紀初期第一次出現在地球上，最後與恐龍、箭石等生物一起於白堊紀晚期滅絕。由於菊石的演化速度很快，分布也很廣，非常適合作為標準化石，地質學家可以使用牠們來確定含有菊石化石的地層的年代。菊石亞綱與現存的頭足綱關係最接近的可能是蛸亞綱。   Descriptions Excellent index fossils, and it is often possible to link the rock layer in which a particular species or genus is found to specific geologic time periods. Their fossil shells usually take the form of planispirals, although there were some helically spiraled and nonspiraled forms.   地點 馬達加斯加 Location Madagascar 參考 Reference http://www.bgs.ac.uk 編者 由 3E (28) 黃曉嫣 於 4/6/2018 編寫 3E (20) 麥博亮 於9/3/2019最後編改   Editor Created by 3E (28) Wong Hiu Yin on 4/6/2018…

名稱 菜德利基蟲化石 Name Redlichia sp. 地質年代 寒武紀 Geological Age Early Middle Cambrian period 描述 古無脊椎動物。三葉蟲綱中出現較早的一類。以最早研究此種化石的英國古生物學家萊得利基而得名。頭鞍窄而長，幾乎伸至外邊緣，三對頭鞍溝，頸環寬大。具頰刺。眼葉新月形，末端與頭鞍相接。邊緣溝深。麵線前支與中軸線交角成45°～90°。胸節多。尾部小，不分節。 Descriptions Redlichia – Oldest Kind Of Trilobites. Redlichia is a genus of trilobite of the Redlichiidae family, from the late Lower and early Middle Cambrian period. Their fossils are found chiefly in Australia and South China (Yunnan). Ancient invertebrates. An earlier class appears in trilobite. It was named after the earliest British paleontologist, Lederlich, who studied this fossil. The head saddle is narrow and long, extending almost to the outer…

名稱扇貝化石 NameScallop Fossil 地質年代 / Geological Age / 描述 貝殼形狀，殼上有直和平行的線，棕色，與它底下的石頭顏色相近。左殼扁平，右殼膨脹；右殼表面約有14條粗放散肋，肋表面平，其上無明顯放散線，肋間溝窄；左殼放散肋相對較細，約有10條，肋寬小於肋間溝。 Descriptions Shell-shaped, parallel and straight line pattern on the shell. Brown in colour. Same colour as the rock. The shell is flat, the right shell expands, the right shell surface has about 14 extensive scatter ribs, the rib surface is flat, it has no obvious diffuse line, the rib ditch is narrow, the shell diffuse rib is relatively small, about 10, the rib width is smaller than the rib ditch. 地點 / Location / 參考…

名稱 耙牡蠣化石 NameRastellum Fossil 地質年代/ Geological Age / 描述它有寬而彎曲的肋骨，導致它被稱為“義齒蛤”。 兩個殼體之間的之字形連接阻止了粗糙的污垢和碎屑進入殼體並損壞其柔軟的身體。像現代牡蠣一樣，它生活在淺海岸水域，包括潮間帶（高潮和低潮之間的區域），並以從海水中濾出的食物顆粒為食。 DescriptionsIt has wide, angled ribs that have led to it being called the ‘denture clam’. The zig-zag join between the two shells stopped coarse dirt and debris entering the shell and damaging its soft body. Like modern oysters it lived in shallow coastal waters including the intertidal zone (the area between high and low tide) and fed on food particles that it filtered out of the sea water. 地點 馬達加斯加 LocationMadagascar 參考 Referencehttps://www.flickr.com/photos/jsjgeology/26076384605https://www.fossilera.com/fossils/fossil-oyster-rastellum-cretaceous 編者 由3D…

名稱角石化石 Name Orthocera Fossil 地質年代   /Geological Age/  描述 It is an invertibrate animal. Orthceras is a genus of extinct animal and they are ancestors to the modern day squid. Originally Orthoceras referred to all nautiloidswith a straight-shell, called an “orthocone”. But later research on their internal structures, such as the siphuncle, cameral deposits, and others, showed that these actually belong to a number of groups, even different orders. Description 角石是一種無脊椎動物，他具有堅硬的外殼，形狀像羊和牛的角，也可以是彎的還是盤卷的。角石死亡之後，肉體很難保存,所以能形成化石的貝殼。直角石的殼形為細長的柱狀椎體，稱為「直角石式殼」（orthoceracone），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。 地點 摩洛哥 Location Morocco 參考 Reference https://www.kidzrocks.com/pages/orthoceras https://zh.wikipedia.org/zh-hk/%E7%9B%B4%E8%A7%92%E7%9F%B3 編者 由 3A (3) 陳善行 於 4/6/2018編寫 由3E (24) 蕭詠霖 於…

名稱 耙牡蠣化石 Name Rastellum Fossil 地質年代   /Geological Age   /描述 這是來自馬達加斯加Tulear省的Rastellum carinatum物種的侏羅紀老化石牡蠣。 它有寬而有角度的肋骨，導致它被稱為’義齒蛤’。 兩個彈殼之間的Z字形連接阻止了粗糙的灰塵和碎屑進入殼體並損壞其柔軟的身體。 像現代牡蠣一樣，它生活在包括潮間帶（高潮和低潮之間的區域）在內的淺海沿岸水域中，並用從海水中過濾出的食物顆粒飼餵。 Description This is a Jurassic aged fossil oyster of the species Rastellum carinatum from Tulear Province, Madagascar. It has wide, angled ribs that have led to it being called the ‘denture clam’. The zig-zag join between the two shells stopped coarse dirt and debris entering the shell and damaging its soft body.
