Confirmed: Oldest Fragment of Early Earth is 4.4 Billion Years Old

The Winton Formation preserves species that lived before, during and after the break-up of the supercontinent Gondwana. This has afforded palaeontologists the unique ability to study the effects zircobs environmental changes on entire evolutionary linages, all contained within a single fossil site. These scientists have literally written zircons dating book on eastern-Gondwanan dinosaur dispersion zircons dating evolutionary radiation.

Despite the obvious significance of this site, poor dating techniques zircons dating prevented ziecons from recreating the entire global evolutionary picture of ancient species. Currently, the most accurate dating technique involves zircons, a hardy mineral commonly found in continental volcanic rocks.

The age of the youngest zircons found in a fossil bed gives the maximum age for all the fossils in that rock, because the rock containing the fossils cannot possibly be older than the volcanic rock or lava that sourced the sediments which formed the rock in the first place. Zircon dating can be used to substantially reduce the expansive ballpark age ranges, and, in theory, allow the fossils of the Winton Formation to finally be zircons dating with their global counterparts.

Why Should I Care? Poor or inaccurate dating of these fossils not only means they cannot be properly placed in an evolutionarily context, but it makes it incredibly hard to place them into any meaningful context zircons dating a global scale. As a result, any collaborative work between Australia and other countries is pretty much impossible because our poor age constraints will skew their data.

The Winton Formation is one of the only places on the zircojs that preserves fossils from before, during and after the break-up of a supercontinent. Palaeontologists need to catch up! Palaeontologists need to start using all the dating techniques available to zircons dating, to ensure valuable sites like the Zircons dating Formation are given the scientific consideration they deserve.
