Dinosaurs died out around 65 million years ago, so how can we find out about what dinosaurs really looked like and how they lived? Schweitzer MH, Wittmeyer JL, Horner JR, Toporski JK (25 March 2005).

It has been suggested that biominerals could be important indicators of extraterrestrial life and thus could play an important role in the search for past or present life on the planet Mars. Furthermore, organic components ( biosignatures) that are often associated with biominerals are believed to play crucial roles in both pre-biotic and biotic reactions. [65]

It’s very rare for living things to become fossilised. Usually after most animals die their bodies just rot away and nothing is left behind. However, under certain special conditions, a fossil can form. She identified ammonites, gastropods, Mosasaur teeth, and even a piece of dinosaur bone. The fossil she was most fascinated with, though, was the coprolite, which—as the guide states—is “fossilized animal poop.” My child dissolved into giggles once she realized she’d found fossilized animal scat. She couldn’t wait to show it to her sisters. A fossil (from Classical Latin fossilis, lit. '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. The totality of fossils is known as the fossil record.Sahney, Sarda; Benton, Michael (2017). "The impact of the Pull of the Recent on the fossil record of tetrapods" (PDF).
