Index fossil

Fosil indeks adalah fosil yang digunakan untuk menentukan dan mengenal pasti tempoh geologi. Mereka bekerja di premis bahawa, walaupun sedimen yang berlainan mungkin kelihatan berbeza bergantung kepada syarat-syarat di mana mereka telah ditetapkan, mereka mungkin termasuk jenazah spesies fosil yang sama. Sekiranya spesies yang bersangkutan berumur pendek, maka sudah pasti bahawa sedimen yang dipertanyakan didepositkan dalam tempoh masa yang sempit itu. Yang lebih pendek jangka hayat spesies, sedimen yang lebih tepat dapat dikaitkan, dan begitu banyak jenis fosil yang sangat berkembang sangat berharga. Fosil indeks terbaik adalah biasa, mudah dikenalpasti pada peringkat spesies, dan mempunyai pengedaran yang luas - jika tidak, kemungkinan mencari dan mengenali satu di kedua-dua sedimen adalah kecil. Ammon memenuhi permintaan ini dengan baik, dan fosil terkenal yang telah digunakan secara meluas untuk ini. Kumpulan penting lain yang menyediakan fosil indeks ialah karang, graptolit, brachiopoda, trilobit, dan echinoid. Conodonts boleh dikenalpasti oleh pakar menggunakan mikroskop cahaya supaya mereka boleh digunakan untuk mengindeks sampel tertentu dengan resolusi yang baik. Gigi fosil mamalia juga telah digunakan.

Index fossils are fossils used to define and identify geologic periods. They work on the premise that, although different sediments may look different depending on the conditions under which they were laid down, they may include the remains of the same species of fossil. If the species concerned were short-lived, then it is certain that the sediments in question were deposited within that narrow time period. The shorter the lifespan of a species, the more precisely different sediments can be correlated, and so rapidly evolving types of fossils are particularly valuable. The best index fossils are common, easy-to-identify at species level, and have a broad distribution—otherwise the likelihood of finding and recognizing one in the two sediments is minor. Ammonites fit these demands well, and are the best-known fossils that have been widely used for this. Other important groups that provide index fossils are the corals, graptolites, brachiopods, trilobites, and echinoids. Conodonts may be identified by experts using light microscopy such that they can be used to index a given sample with good resolution. Fossilized teeth of mammals have also been used.
