Dinosaur Fossilization and Preservation

The video explores the process of fossilization, starting with a dinosaur's last day and how its remains were buried and transformed into fossils over millions of years. It explains geological processes like uplift and erosion that expose fossils, and why most fossils are marine. The video also highlights rare fossil finds of dinosaurs preserved in action and discusses other fossil types like footprints and impressions.

What materials buried the dinosaur's bones over millions of years?

• Only mud

• Mud, sand, and volcanic ash

• Only sand

What role did water play in the fossilization process?

• It prevented fossilization.

• It left behind minerals that turned the bones to stone.

• It dissolved the bones.

• It washed away the bones.
