"Ambush at Hell Creek" is a companion jigsaw puzzle to the family game Fossil Canyon.

"Ambush at Hell Creek" is inspired by the many fossils of T. rex and Triceratops that have been found in the Hell Creek Formation, sedimentary rocks that were deposited 68 to 66 million years ago in present-day Montana, Wyoming, North Dakota, and South Dakota, USA.
