New Dinosaur Species Discovered
The Springfield Science Museum made two very exciting discoveries recently, and they both involve bones that have been on display in the museum’s dinosaur hall for quite some time. One may be from an entirely new species of the tyrannosaur family.
One of the bones has been a part of the museum’s collection since 1934. It was known as a “large sauropod humerous”. It was found in New Mexico and is from Alamosaurus sanjuanensis, the largest dinosaur that ever lived in North America. It was identified by paleontologist Sebastian Daiman. The pubis bone from a Tyrannosaurus rex got a wrong notation on it and was marked that it had come from Hell Creek Montana. It has now been found to come from the same formation in New Mexico where the newly identified Alamosaurus bone was found and represents a new species of Tyrannosaurus. This information is being compiled into a paper for an academic peer review and David Stier, Director of the museum, wants to be sure that there are enough different characteristics to confirm a new species. He says this discovery is proof that there are so many more things that we’ve yet to find.

Cretaceous Period Jigsaw Puzzle Scientists from around the world are amazed over a staggering deposit of dinosaur bones in Edmonton. Discovered in the 1980s and excavated by researchers over the last eight summers, it includes the fossilized remains of different types of dinosaurs that were likely traveling together when they died. The bones represent a mixed population of dozens of animals, young and old. It looks like they were moving as a herd when something killed and buried them. The Canadian Journal of Earth Sciences says the find is so monumental that it will provide secrets about the dinosaurs for generations to come. So far the site has yielded remains from giant duck-billed Edmontonosaurs, large meat-eating Albertosaurs, two small predators related to Velociraptors, an ostrich-like ornithomimid and a horned dinosaur related triceratops.
The precise location of the site is being kept secret to prevent vandalism. It covers miles of land and an extinct riverbed. Bones have been excavated there since 2006 by a team led by Philip Currie, the University of Alberta’s Canada Research Chair in Dinosaur Paleontology. The discovery of fossilized remains of a triceratops is one of the biggest surprises, along with teeth that apparently fell out as predators were ripping the skin of smaller dinosaurs. All of the animals are from the same era, but it is still unknown whether they died at the same time. Reference: Marty Klinkenberg, Edmonton Journal-Dec. 17. 2014
