Velociraptor fossils date to between 75 and 71 million years ago. That was during the Campanian and then the Maastrichtian stages of the Cretaceous period.
three factors are climate CLIMATE CLIMATE CLimate
Marine West Coastal Climate, Miditerranean Climate, Humid Continental climate, Humid Subtropical Climate. the answer !
Climate regions refer to areas with distinct climate, for example, Hawaii's climate region is Tropical.
the effect is that the climate changes into a cooler or warmer climate.
Recent not, but it is found there extensivly in ancient strata of Maastrichtian as pollen fossils (Dettmann et al 1990).
Pteortrigonia thoracica is an extinct species of bivalve that lived about 65-70 million years ago in the Maastrichtian age of the late Cretaceous Period.
Velociraptor fossils date to between 75 and 71 million years ago. That was during the Campanian and then the Maastrichtian stages of the Cretaceous period.
Triceratops fossils date to between 68 and 65.5 million years ago. This was during the Maastrichtian stage of the Cretaceous period of the Mesozoic era.
Ankylosaurus remains date to between 66.5 and 65.5 million years ago. This was during the Maastrichtian stage of the Cretaceous period of the Mesozoic era.
Triceratops lived approximately 70-65 million years ago during a period of time called the Late Cretaceous (or Senonian), in a smaller section of time known as the Maastrichtian.
Ankylosaurus lived between 66.5 and 65.5 million years ago, at the end of the Maastrichtian stage, the last stage of the Cretaceous period. The Cretaceous period was the third and final period of the Mesozoic era.
The dinosaurs died out 65.5 million years ago. That was the very end of the Maastrichtian stage, which was the last stage of the Cretaceous time period. The Cretaceous was the last period of the Mesozoic era.
T-rex existed during the end of the Maastrichtian stage of the Cretaceous period. That was about 66 - 65.5 million years ago. They died out during the K-T extinction event.
