FL014 Trilobite Fossil

名稱 三葉蟲化石張氏蟲屬 Name Trilobite 地質年代 / Geological Age / 描述 三葉蟲綱(學名:Trilobita)的動物通稱三葉蟲,是節肢動物門中已經滅絕的一綱。牠們最早出現於寒武紀,在古生代早期達到頂峰,此後逐漸減少至滅絕。最晚的三葉蟲(砑頭蟲目)於二億五千萬年前二疊紀結束時的生物集群滅絕中消失。三葉蟲是非常知名的化石動物,其知名度可能僅次於恐龍。在所有的化石動物中三葉蟲是種類最豐富的,至今已經確定的有九(或者十)個目,一萬五千多個物種。大多數三葉蟲是比較簡單的、小的海生動物,牠們在海底爬行,通過過濾泥沙來吸取營養。牠們身體分節,有帶溝將身體分為三個垂直的葉。在世界各地都有發現過其化石。 DescriptionsTrilobites (meaning “three lobes”) are a group of extinct marine arachnomorph arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago), and they flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Devonian, all trilobite orders except…

FL011 Pygurus Depressus Asteroid Fossil

名稱 海星化石 Name Pygurus depressus Echinoid Fossil (Polished) 地質年代 / Geological Age / 描述 海星,又稱海盤車, 是海星綱棘皮動物的統稱,雖然海星在世界各大洋均有分佈,但是海星的化石卻非常罕見。這是由於海星的脊索由100多個鈣質骨節組成,這些骨節由軟組織連接,海星死亡後,軟組織消亡,這些鈣質骨節就被打散,形成不了完整的海星化石.完整的海星化石極具收藏價值和考古價值。   Descriptions Pygurus depressus echinoid specimens, fossilised, which have been polished, highlighting morphological features such as the petals on the surface of the specimen.

FL008 Rastellum Fossil

名稱耙牡蠣化石 Name Rastellum 地質年代侏羅紀中期—白堊紀晚期 Geological Age Mid-Jurassic – Late Cretaceous 描述 蛤目、牡蠣科 俗稱:雞冠牡蠣 在蟲的頂端突起,在其球形身上有刺勾。殼管狀,殼表面佈滿深溝槽分割的脊。 生活環境與習性:生活於溫暖淺海,議殼嘴附著於碎殼或珊瑚上。這是來自馬達加斯加Tulear省的Rastellum carinatum的侏羅紀老化石牡蠣。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。附註:兩殼連接的端部隱蔽,可能是為了防備其他肉食動物的攻擊。 DescriptionsIt is a knot like protrusion at an extreme end of a tapeworm, it is globular, spiny and has hook on it. 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…
