* 표본명: 어류화석(경골어류), Ray-Finned Fish(fossil), 鱼类化石(硬骨鱼类)

* 학명: Actinopterygii

* 분류: 동물화석


* 표본정보:

  경골어류는 뼈로 이루어진 골격을 가지고 있다. 고생대 초기부터 중생대 까지 크게 번성하였으며, 물에서 육지로 이동한 최초의 척추동물이자 가장 원시적인 동물로 여겨지며 지금까지 멸종하지 않은 만큼 다양한 지질에서 다양한 화석이 발굴되고 있다.

 
  Ray-finned Fish are sometimes known as bony fish because of their relatively hard bones.

  Ray-finned fish are the most primitive of all vertebrates and are the ancestors of the first vertebrate species to live on land. Ray-finned fish are found in any sort of water environment, and can be found thousands of meters below the ocean’s surface or even in a shallow mountain brook. These fish evolved rapidly during the paleozoic period, hence these types of fish have a plethora of different classifications. Most creatures that breath through gills are, in fact, ray-finned fish. The oldest and most primitive forms of ray-finned fish are ‘armored fish’ which had boney plates to protect them.


  硬骨鱼类全身骨架由骨头组成,繁盛于古生代初期至中生代。该标本为中生代时期的硬骨鱼类化石。是最初从水中移动至陆地生活的脊椎动物的祖先,被认为是最原始的动物,如今也依然没有灭绝。化石已在多样的地质环境中被发掘。
