It is greatly elongated along the hinge line, which extends outward…
名稱 海胆化石 Name Sea Urchin Fossil 地質年代 / Geological Age / 描述 海膽化石外形呈扁平圓盤狀，表面有五枚花瓣紋。 外形呈扁平圓盤狀，表面有五枚花瓣紋。因為海膽是由相互交鎖石灰質塊板組成，很容易形成化石。 海膽是棘皮動物門分類下的一個綱，其正式學名是海膽綱（Echinoidea），意思是「像豪豬般的動物」），又名「海刺蝟」。海膽生活在海洋中，廣泛分布於世界各地的海洋，從潮間帶至數千公尺的深海底都可發現其蹤跡。全世界現存約有1000種海膽，化石700種以上。 Descriptions The shape of Sea Urchin Fossil is a flat disk with five petal patterns on the surface. Fossil echinoids closely resemble some living sea-urchins which helps us to understand how they must have lived. Sea urchins are typically spiny, globular animals, echinoderms in the class Echinoidea. About 950 species live on the seabed, inhabiting all oceans and depth zones from the intertidal to 5,000 metres (16,000 ft; 2,700 fathoms).…
