The known fossils of Quetzalcoatlus were discovered in Big Bend National Park, Texas. The genus Quetzalcoatlus is based on fossils discovered in rocks pertaining to the Late Cretaceous Javelina Formation in Big Bend National Park, Texas. Remains of dinosaurs and other prehistoric life had been found in the area since the beginning of the 20th ...
The outcrop, situated in the middle strata of the formation about 90 meters below the K-Pg boundary and within the local range of Alamosaurus fossils and below two sites that have yielded Quetzalcoatlus fossils, was dated to 69.0 plus or minus 0.9 million years old in 2010. [2] Indeterminate chasmosaurinae fossils have also been as well. [5]
In 1992, a partial pterosaur skeleton was found and excavated in Upper Cretaceous strata of Dinosaur Provincial Park in Alberta, more precisely in a layer of the Dinosaur Park Formation that dated back to the late Campanian (between 76.7 and 74.3 million years ago). The excavation site was located near the lower or older boundary of this range.

New research shows that Homo sapiens traveled from Africa to East Asia and toward Australia up to 86,000 years ago.
Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed.
