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 Quilchena fossil locality is dated to 51.5 ± 0.4 Ma corresponding to the Early Eocene Climatic Optimum (EECO), and is reconstructed as the warmest and wettest of the Early Eocene upland sites from the Okanagan Highlands of British Columbia and northern Washington State. Mean annual temperature (MAT) is estimated from leaf margin analysis ...

Washington state is a hotbed for minerals, gemstones, crystals and fossils, making the Evergreen state a popular site for rockhounding. Whether in an official group or going solo, rockhounding is ...
During the 1875 field work, fossil collections were made in the Quesnel region. [6] Two years later, in 1877, the expedition explored the Okanagan, Nicola, and North Thompson valleys with field collecting along areas of the Similkameen River, Whipsaw Creek and Nine-Mile Creek, north at around Quilchena, and at several areas near Kamloops.

Reexamination of the fossil in 2000 showed the specimen belongs to the Trionychidae family of soft shelled turtles. [13] In 2023, the first articulated fossil fish was identified from the formation, which was a fragmented specimen of Phareodus. [14] Eocene fossil trackways are found in the Chuckanut Formation, composed of birds, [15] mammals ...
This list of fossil sites is a worldwide list of localities known well for the presence of fossils. Some entries in this list are notable for a single, unique find, while others are notable for the large number of fossils found there. Many of the entries in this list are considered Lagerstätten (sedimentary deposits
