The human bones excavated by Sellards were passed around various institutions for study. By the time carbon-14 dating of fossils became possible, about 35 years after the discovery of Vero Man, some of the bones had been lost, and others had been rendered unusable for such testing due to the way they had been preserved with chemicals.
The Wheeler Shale (named by Charles Walcott) is a Cambrian (c. 507 Ma) fossil locality world-famous [1] for prolific agnostid and Elrathia kingii trilobite remains (even though many areas are barren of fossils) [2] and represents a Konzentrat-Lagerstätte.

Originally, it was an entire mummified mammoth carcass. [2] Beresovka Mammoth Berezovka River, Siberia ...
Plant macrofossils include leaf, needle, cone, and stem debris; and can be used to identify types of plants formerly growing in the area. Such botanical macrofossil data provide a valuable complement to pollen and faunal data that can be used to reconstruct the prehistoric terrestrial environment.
There are a large variety of biofacts that have the potential to give insight into how civilisations operated in the past. Plant remains are a common and key ecofact that provide an importance source of information because they can be used to reconstruct the way past societies have interacted with their environment. [5]
Small shelly fossils are composed of a variety of minerals, the most important being silica, calcium phosphate and calcium carbonate. [3] The minerals used by each organism are influenced by the chemistry of the oceans the organism first evolved in, but then continue to be used even if the ocean chemistry changes.
Like other fossils, coprolites have had much of their original composition replaced by mineral deposits such as silicates and calcium carbonates. Paleofeces, on the other hand, retain much of their original organic composition and can be reconstituted to determine their original chemical properties, though in practice the term coprolite is also ...
Because nummulites are very abundant, easy to recognize, and lived in certain biozones, they are used as guide fossils.It is worth highlighting that thanks to the appearance of Nummulites tavertetensis in the Shallow Bentic Zone 15 (SBZ 15), it was possible to date the oldest fossil remains of Sirenio in Western Europe found in a new paleontological site, in Santa Brígida, Amer (La Selva ...
