Fosillised Footprints, Pontdrift, Soutpansberg District These fossilised reptile footprints occur in sandstone where there was a dune in earlier times which was later covered by basalt flows. The animals of tile vicinity presumably fled to the dune where a large number of fossilised prints of various animals a Type of site: Trace fossils.

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. - National Park Service
Wisconsin’s Cambrian rocks have also produced fossils of more aglaspidid (a grouping of arthropods closely related to trilobites) species (around 12) than those of any other state. A portion of central Wisconsin known as Blackberry Hill is a Konservat-Lagerstätte famous for its many types of trace fossils, mass strandings of jellyfish, and ...
Adding to this conundrum are fossilized footprints of bird-like tracks that are 210 million years old—a good 60 million years before the arrival of the genus Archaeopteryx, one of the oldest ...
The footprints date to about 21,000 to 23,000 years ago, based on radiocarbon and optically stimulated luminescence dating techniques, researchers said on Thursday, showing that our species Homo ...
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 ...
