Since the "Share the Adventure: Discovering Dinosaurs" BLM satellite broadcast in October 2001, there have been significant developments in the Grand Staircase-Escalante National Monument area. The first was the reclassification of the bones as those of different dinosaur. The second was the opening of a new visitor center with an extensive dinosaur exhibit. New discoveries continue to be made within the Monument.
After their collection in 2001, the Monument's hadrosaur (duckbilled dinosaur) bones first went to the Museum of Northern Arizona paleontology lab for safekeeping, and were subsequently moved to the BLM lab in Kanab, Utah, in late spring 2003. With the help of three volunteers, over the next 10 months, Monument paleontologist Alan Titus prepared the fossils for display.
In the course of preparing the specimen, Dr. Titus learned that additional fossil materials, notably parts of a hip, had been collected from the same Monument site by Museum of Northern Arizona paleontologists in the mid-1980s.

Dr. Titus's comparison of the 1980s materials with other positively-identified hadrosaur specimens led him to conclude that those hip portions, as well as the "Share the Adventure!" bones collected in 2001, were not those of the odd, crested hadrosaur, Parasaurolophus, as previously believed. Rather, they were more similar to those of a non-crested hadrosaur genus, Gryposaurus.The skeleton was finished in May of 2004 and transported to the new Big Water Visitor Center--one of five new visitor centers serving the Grand Staircase-Escalante National Monument--for exhibition in June of 2004. The Big Water center, which has a Late Cretaceous paleontology theme, features a 40-foot-long mural by a world-renowned paleolife restoration artist, Larry Felder.
The center features fully-accessible learning experiences and programs that interest and engage visitors of all ages and backgrounds. The hadrosaur’s bones will be on display there for at least the next few years. Class visits are encouraged!
New discovery: The complete skulls of two Gryposaurus-like hadrosaurs were found within the Monument in 2003. These fossils were collected by scientists during the summer and fall of 2004; work has already begun on their preparation.
