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 ...

Scientists have identified a new giant horned dinosaur species that roamed across modern-day North Africa about 95 million years ago, despite its fossilised remains being destroyed during the ...
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 ...
Older fossils lay even deeper beneath the bone bed. These 8.9-million-year-old rocks included fossilized bones of fish and marine mammals. Experts also found teeth from juvenile megalodons and ...
' obtained by digging ') [1] is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants.
