Here's a video just posted at the Royal Tyrrell Museum's YouTube video page. Donald Henderson shows an amazing "bloat and float" ankylosaur that was recovered from marine sediments near Fort McMurray, Alberta, Canada. It's interesting that the skeleton was uncrushed. Lori and I did some prep work on the therizinosaur Nothronychus graffami which was found in marine sediments, and most of its bones were extremely flattened. The ankylosaur is a very cool, very rare find.
