Follow the links on the Dinosaurs in the Deep web site and you'll find some interesting stuff, apparently well-written, about the sinking of Mount Temple, and the shipment of dinosaur and other fossils on her when she went to the bottom.
Hadrosaurs! On board! Great! Makes me want to go delving into the palaentological literature to get the list of what they think went down with her. Would be interesting to see how the ideas of recovery develop.
