Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends. Another term, "zone fossil", is used when the fossil has all the characters stated above except wide geographical distribution; thus, they correlate the surrounding rock to a biozone rather than a specific time period.
The closest is the Dinosaur Genera List, compiled by biological nomenclature expert George Olshevsky, which was first published online in 1995 and was regularly updated until June 2021. [ 1 ] [ 2 ] The most authoritative general source in the field is the second (2004) edition of The Dinosauria .
The fossil examined in the study, collected during a 2011 expedition by the Antarctic Peninsula Paleontology Project, was found encased in rock that dated back 68.4 to 69.2 million years and ...
Unearthed in a rock layer dating back to the Triassic period, between 252 million and 201 million years ago, the Gondwanax paraisensis fossil comes from the time when dinosaurs as well as mammals ...
The trend continued in the 20th century with additional regions of the Earth being opened to systematic fossil collection. Fossils found in China near the end of the 20th century have been particularly important as they have provided new information about the earliest evolution of animals, early fish, dinosaurs and the evolution of birds.
