ANKYLOSAUR TRACKWAY

Fossil Field Trip / Ankylosaur Trackway
After an exciting hike in the dark through the woods and down a steep incline, we reached the river. The tracks in this photo are from a type of armored dinosaur that date from the very end of the Cretaceous, between 68-66 million years ago.

Imagine a meandering armored tank munching on ferns and low-growing vegetation. There are two types of footprints at the Wolverine River Tracksite, the meat-eating theropods (at least four different sizes) and the slow, lumbering plant-eating ankylosaurs.

The trackway you see here was made by one of those armored lumbering ankylosaurs and a few of the prints carry skin impressions. Filling the prints with water and using lamplight was genius for viewing tracks as they are all but invisible in the bright sunlight.

Filling the prints with water and using light in a clever way was a genius idea for viewing tracks that are all but invisible in bright sunlight by day.
