World's Largest Dinosaur
The "World's Largest Dinosaur" is the name of a model "Tyrannosaurus rex" located in the town of Drumheller in the Canadian province of Alberta. Built of fiberglass and steel, has a height of and a length of , considerably larger than the largest known specimens of the actual dinosaur which reached up to in length, and was up to tall at the hips. The dinosaur was built while former mayor Phil Bryant was in his term.
Puertasaurus
Due to a lack of better material, the size of "Puertasaurus" is difficult to estimate. Novas estimated the new species was approximately long and weighing between . This would place it as one of the largest dinosaurs, only rivaled in size by its relative "Argentinosaurus", which has been estimated at up to in length and in mass. The discovery of the more complete "Futalognkosaurus" revealed these previous estimates were likely too high. In 2012, Thomas Holtz estimated "Puertasaurus" to have been potentially long. In 2013, the entire neck was estimated to have been approximately long by Mike Taylor and Matt Wedel. Later the same year, Scott Hartman made a reconstruction that suggests a total length of , slightly shorter than other estimates. In 2016, Gregory S. Paul estimated a length of and a weight of at least . In 2017, paleontologist José Carballido and his colleagues estimated its mass at roughly , which was lighter than "Patagotitan", a more complete giant sauropod.
