Fossil Collector: Mark P.
Location: Mancos Shale
[Note: The Mancos Shale is an Upper Cretaceous formation of Utah and the Colorado Plateau. This find is something we we we could pick up and take a closer look at, but the general impression of the black areas reminds us of large fish bones and scales. The size of these are a bit daunting. For your dinosaur theory, it is not unusual to find terrestrial animal fossils in marine deposits because a watery environment is generally needed for them to become fossils. Terrestrial animals are washed into rivers, marshes and oceans all the time. As a famous example, the first dinosaur discovered in the United States is Hadrosaurus foulkii which was uncovered in a Cretaceous marine deposit in Haddenfield, New Jersey. Hopefully someone familiar with these fossils can leave a comment for us.]
