CLEAN: Dino footprints enter record books

The video discusses the discovery of animal footprints on limestone, which were once mud. These footprints, both of feet and less visible hands, are well-marked but eroded. The video highlights the collaboration between geologists from different institutions and discusses techniques to maintain sediment plasticity for preservation.

What evidence was found on the limestone slabs?

• Fossilized plants

• Animal footprints and handprints

• Ancient human tools

• Dinosaur bones

How are the footprints described in the video?

• Circular and random

• Deep and well-marked

• Faint and barely visible

• Shallow and eroded

What pattern do the footprints follow?

• Alternating left and right

• In a straight line

• Randomly scattered

• In a circular pattern

Which organizations collaborated on the geological study?

• Société des naturalistes de Yonhax and University of Lyon

• National Geographic and Smithsonian Institution

• Geological Society of America and NASA

• British Geological Survey and Harvard University

What is the purpose of keeping the sediments moist?

• To prevent them from drying out

• To maintain their plasticity

• To make them easier to transport

• To enhance their color
