From regular maintenance of objects on permanent display to initiatives such as the Maiasaur
fossil preparation lab--which in the mid 1990s allowed visitors to watch as the fossil was painstakingly released from bedrock that encased it--in situ conservation is essential to the ROM's protocol of keeping the collection in stable condition.
The Museum of the Rockies in Montana, USA now owns Egg Mountain, noted for the discovery of Maiasaur
fossils (Horner and Dobbs 1997).
The fossil evidence even shows that maiasaur adults stuck around to protect and raise their young.
he said, gesturing to the reddish plastic skin of the animatronic maiasaur.
Horner pointed to an animatronic display of maiasaurs tending a nest of young.
In addition to meeting the ferocious (but, in this case, harmless) T-Rex, piece together the lives of dinosaurs from evidence trapped in the earth, search for new evidence, build your own Dromaeosaurus skeleton and dissect a 10-foot, fabric Maiasaur
Maiasaur, in fact, means good mother reptile, and the name was conferred by Horner after he discovered the fossilized remains of dinosaur nests along with eggs, shell fragments, and dinosaur nestlings.
The growth plates--never before seen in dinosaur fossils--were discovered in the well-preserved bones of young maiasaurs found in the nesting sites of the Two Medicine Formation in northwestern Montana.
