In 2021 they were radiocarbon dated, based on seeds found in the sediment layers, to between 21,000 and 23,000 years ago. [1] That date range is currently the subject of scientific debate, but if it is correct, the footprints would be one of, if not the oldest evidence of humans in the Americas. The earlier theory held that human settlement of ...
Fossilized footprints discovered in New Mexico indicate that early humans were walking across North America around 23,000 years ago, researchers reported Thursday. The first footprints were found ...
The technique is used to determine the age of organic material as old as roughly 60,000 years based on the decay of an isotope called carbon-14, a variant of the element carbon. Living organisms ...
The skeleton has primitive features, but has mostly lost the salamander-like traits of its ancestors. It has a skeleton designed to absorb the force of jumping with its hind legs and tail. It also has long hip bones, long hind leg bones, and long ankle bones, all similar to modern frogs, and is as of 2009 the earliest true frog. [1]
