The large T. rex will transfer to a brand new exhibition area within the museum, whereas a forged of the skeleton of the most important-recognized dinosaur, Patagotitan mayorum, will take the spot Sue now occupies within the museum’s Stanley Area Corridor.
Patagotitan, an extended-necked, 4-legged plant-eater that was 122 ft lengthy and weighed 70 tons, lived in Argentina one hundred million years in the past, greater than 30 million years earlier than T. rex stalked western North America. The most important land animal on report, it was a member of a dinosaur group referred to as titanosaurs.
The museum subsequent spring will unveil the fiberglass Patagotitan skeleton, which is being forged from fossils of seven Patagotitan people, and for 2 years will show a number of the real fossils, together with an eight-foot thighbone.
Named for the lady who found the fossils in South Dakota in 1990, Sue is the most important, most full and greatest-preserved Tyrannosaurus rex ever unearthed. The museum purchased the fossils at public sale for $eight.four million.
Sue shall be taken down in February and put up once more with noteworthy modifications in anatomy and stance in its new exhibition corridor in spring 2019, museum scientists stated.
“We’re making a number of changes to the skeleton to mirror new and improved information,” stated paleontologist Pete Makovicky, the museum’s affiliate curator of dinosaurs.
Probably the most putting change, Makovicky stated, would be the addition of gastralia, bones resembling a further set of ribs spanning the stomach which will have offered structural help to assist the dinosaur breathe. Including these bones will illustrate simply how large Sue was and that it boasted a bulging stomach, he added.
The scientists concluded that the bone mounted as Sue’s wishbone was misidentified in 2000 and they’ll exchange it with the dinosaur’s precise wishbone, or furcula, the fused collar bones typical of meat-consuming dinosaurs and their evolutionary descendants the birds.
Additionally they will regulate the ribs to supply a slimmer, much less barrel-formed chest, and organize the appropriate leg so Sue just isn’t crouching as a lot.
“Typically if you do one thing as costly as mounting a vertebrate fossil skeleton for show you solely get one shot at it. I am completely happy we will repair and replace this unimaginable fossil,” stated paleontologist Invoice Simpson, who heads the museum’s geological collections.
