More footprints from White Sands National Park. The 61 footprints are located at the shore of a dried up ice age era lake, Lake Otero in the Tularosa Basin. [5] The prints were laid on the shores of the now-dry lake at a time when the climate in the region was less arid.
Tree remains that have undergone petrifaction, as seen in Petrified Forest National Park. In geology, petrification (from Ancient Greek πέτρα (pétra) 'rock, stone') is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.
A fossil track or ichnite (Greek "ιχνιον" (ichnion) – a track, trace or footstep) is a fossilized footprint. This is a type of trace fossil. A fossil trackway is a sequence of fossil tracks left by a single organism. Over the years, many ichnites have been found, around the world, giving important clues about the behaviour (and foot ...
The fossils were discovered in the mountains of northern Italy's Lombardy region after the snow and ice that once covered them melted away, scientists say, as a result of the ongoing climate crisis.
The fossilized footprints were made public in 2021 and date back between 21,000 and 23,000 years, according to new research that builds upon past evidence.
The 2021 study dated the footprints using radiocarbon dating to determine the age of seeds of a common aquatic plant called spiral ditchgrass found alongside the fossilized foot impressions.
Neoichnology (Greek néos „new“, íchnos „footprint“, logos „science“) is the science of footprints and traces of extant animals. Thus, it is a counterpart to paleoichnology, which investigates tracks and traces of fossil animals.
Archaeological materials, such as bone, organic residues, hair, or sea shells, can serve as substrates for isotopic analysis. Carbon, nitrogen and zinc isotope ratios are used to investigate the diets of past people; these isotopic systems can be used with others, such as strontium or oxygen, to answer questions about population movements and cultural interactions, such as trade.
