The Maastrichtian Age, named after the city of Maastricht in the Netherlands, indicates a specific time period in the late Cretaceous epoch, approximately 72 to 66 million years ago. Its nomenclature suggests a geological significance tied to the region's rock formations and fossil records, highlighting its importance in understanding the end of the age of dinosaurs. The name also implies that this period is characterized by significant geological and biological events, including the mass extinction that marks the boundary between the Cretaceous and Paleogene periods.
CRETACEOUS PERIOD144-65 Million Years Agoand in the really really really REALLY late jurassicbut mostly cretaceous
scientist have been able to infer the relationships between the major groups of vertebrates by bones
He hears the welcome sound.
her name is scratte ;) Littlegeek edit: And she is HOT!!!!!!!
The dating method that determines a fossil's age by comparing it to other fossils is called relative dating. This technique involves placing fossils in a chronological sequence based on their position within sedimentary rock layers, known as strata. By examining the sequence and the types of fossils present, scientists can infer the relative ages of the fossils in relation to one another. Relative dating does not provide an exact age but rather indicates whether a fossil is older or younger than another.
The Maastrichtian age is the last stage of the Late Cretaceous period, spanning from approximately 72.1 to 66 million years ago. It is characterized by significant geological and biological changes, including the diversification of flowering plants and the dominance of dinosaurs. The Maastrichtian is also notable for the mass extinction event at its end, which led to the demise of many species, including the non-avian dinosaurs. This age is named after the Maastricht area in the Netherlands, where key geological formations from this period are found.
The Maastrichtian Age is the final age of the Cretaceous Period, from 70-65 million years old. Over 100 dinosaurs were alive at this time. Tyrannosaurus, Triceratops, and Ankylosaurus are just 3 of these.

Best estimates put the Earth's age at approximately 4.6 billion years old.
