When Sharks Swam the Great Plains

The video explores the Western Interior Seaway, an ancient ocean that once split North America. It discusses its formation, the diverse marine life it hosted, and how predators coexisted through niche partitioning. The video also covers the decline of the Seaway and its lasting impact on the region's geology.

What was the Western Interior Seaway known for?

• Its rich aquatic life

• Its vast deserts

• Its dense forests

• Its mountain ranges

What geological event contributed to the formation of the Western Interior Seaway?

• The melting of polar ice caps

• The collision of the Farallon Plate with the North American Plate

• The eruption of a supervolcano

• The formation of the Appalachian Mountains

Which of the following was a common predator in the Western Interior Seaway?

• Tyrannosaurus Rex

• Stegosaurus

• Squala Corax

• Velociraptor

How did predators in the Western Interior Seaway manage to coexist?

• By reducing their population

• Through niche partitioning

• By migrating to different regions

• By forming alliances

What is niche partitioning?

• The adaptation of species to different ecological roles

• The division of land among different species

• The extinction of weaker species

• The migration of species to new habitats

Which predator was known for having a specialized fish-based diet?

• Plesiosaurus

• Xiphactinus

• Tylosaurus

• The rise of the Rocky Mountains

What evidence of the Western Interior Seaway can still be found today?

• Fossil-bearing limestones

• Volcanic rocks

• Glacial deposits

• Sand dunes

What type of fossils are commonly found in the Great Plains today?

• Mammoth tusks

• Ancient human artifacts

• Cretaceous seashells

• Dinosaur bones

What is a notable feature of the limestone buildings in central Kansas?

• They are made of volcanic rock

• They contain Cretaceous seashells

• They are covered in moss

• They are built on ancient glaciers
