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.
This is a photograph of an ankylosaur trackway filled with water and lit by lamplight along Wolverine River, a research site of Lisa Buckley, one of two magnificent paleontologists working in the area.
Some of the prints contain skin impressions, which is lucky as many of the prints are so shallow that they can only be recognized by the skin impressions.
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.
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.
