FL125 Calamites Stem Fossil

名稱 蘆木屬莖幹化石Name Calamites stem fossil地質年代 石炭紀Geological Age Carboniferous描述 蘆木屬是已絕種的高大的樹狀蕨類,和現代的木賊屬是近親。生長在潮濕的沼澤地帶中。在石炭紀時頗為興盛,和鱗木、封印木等一同形成廣大的蕨類雨林。它們的高度可達30公尺。其遺骸在地底下經長久的化學及物理作用後,形成現代人類最重要的燃料資源煤炭及天然氣。Description Calamites is a genus of extinct arborescent (tree-like) horsetails to which the modern horsetails (genus Equisetum) are closely related. Unlike their herbaceous modern cousins, these plants were medium-sized trees, growing to heights of more than 30 meters (100 feet). They were components of the understories of coal swamps.地點 蘭開夏,英國Location Lancashire, U.K.參考 Reference https://en.wikipedia.org/wiki/Calamites編者 由卓志鵬博士於7/4/2020編寫 _________ 於17/1/18最後編改  Editor Created by Dr. Chuck Chi Pang on 7/4/2020 Last modified by ________ as on 17/1/2018

FL124 Eopecten Inequivalvis Bivalve Fossil

名稱 海扇蛤化石Name Eopecten Inequivalvis bivalve fossil地質年代 侏羅紀Geological Age Jurassic描述 它是一種已絕種的雙殼類扇貝。它們具有對稱的外殼,與其他雙殼類動物相比,外殼相當平坦,並且沿其表面有許多坑紋。這些殼由碳酸鈣組成,它們在鉸鏈處靠結締組織連接和控制開合,從流線型殼中推斷出,它們也積極游動以尋找食物或逃避掠食者。  Description It is an extinct species of bivalve belonging to the pecten group. They have a symmetrical shell which is fairly flat when compared to other bivalves and has numerous ribs along its surface. Their shells are composed of calcium carbonate. They are separate and join only at the hinge by connective tissues. It is also very likely inferred from the streamlined shell that this species also actively swam in search of food or to…

FL119 Bryozoan Fossil

名稱 拋光苔蘚蟲化石Name Polished Bryozoan fossil地質年代 奧陶紀Geological Age Ordovician描述 苔蘚蟲是一種固定生活的群體動物。群體的形狀各不相同,有的像被單一樣蓋在貝殼或岩石上;有的則像小樹或網狀複葉。每個群體都由數千個單體組成,每個單體都有管狀或盒狀的骨骼。牠們的外觀雖然很像植物,但具一套完整的消化器官,包括口、食道、胃、腸臟和肛門等。其個體小,不分節,具體腔。 體外分泌一層膠質,形成群體的骨胳。蟲體前端有口,口的周圍有一冠狀物,稱「總擔」,其上生許多觸手。消化道呈U字形,口和肛門十分靠近。無排泄和循環器官。Description Bryozoa are a phylum of aquatic invertebrate animals. Typically about 0.5 millimetres (0.020 in) long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a “crown” of tentacles lined with cilia. Most marine species live in tropical waters, but a few occur in oceanic trenches, and others are found in polar waters. One class lives only in a variety of freshwater environments, and a few members of a…

FL117 Belemnite Shell Fossil

名稱 拋光箭石化石Name Polished Belemnite Shell fossil地質年代 石炭紀Geological Age Carboniferous描述 箭石在許多方面都與現代的魷魚相當接近,而且與現代的烏賊關係密切。箭石也擁有墨汁,不過牠們有10條大約相同長度的觸腕,其中並沒有特別長的觸腕。它在侏羅紀與白堊紀時數量相當多,所以牠們的化石在中生代的海洋岩層中相當豐富,經常伴隨著菊石類出現。不過箭石也跟菊石一起在白堊紀末期滅絕了。Description Belemnitida is an extinct order of squid-like cephalopods that existed from the Late Triassic to Late Cretaceous. Unlike squid, belemnites had an internal skeleton that made up the cone. The parts are, from the arms-most to the tip: the tongue-shaped pro-ostracum, the conical phragmocone, and the pointy guard. The calcitic guard is the most common belemnite remain. Belemnites, in life, are thought to have had 10 hooked arms and a pair of fins on the…
