We all like to laugh at the T-Rex for having silly looking arms and we all completely forget about the even more ridiculous Carnotaurus arms.

During the Permian Period, Earth’s crustal plates formed a single, massive continent called Pangaea. In the correspondingly large ocean, Panthalassa, marine organisms such as brachiopods, gastropods, cephalopods (nautiloids and ammonoids), and crinoids were present. On land, reptiles replaced amphibians in abundance. The most devastating incidence of mass extinction in Earth’s history marked the end of the Permian Period.

The world’s biggest known Tyrannosaurus rex — one of the largest and most fearsome carnivores of all time — lived about 66 million years ago (Cretaceous Period) in what is now Saskatchewan, Canada.
Scotty was 42.7 feet (13 m) long and weighed approximately 8,870 kg.
The large, relatively complete (roughly 65%) skeleton was found in a layer of the Frenchman Formation near Eastend, Saskatchewan, in 1991.
The bones were encased in iron-stained, heavily-cemented sandstone, which took more than a decade to remove.
It’s only recently, after several more years piecing together the specimen like a jigsaw puzzle, that paleontologists have been able to study the specimen.
“This is the rex of rexes,” said Dr. Scott Persons IV, a paleontologist in the Department of Biological Sciences at the University of Alberta.
“There is considerable size variability among Tyrannosaurus. Some individuals were lankier than others and some were more robust.”
“Scotty exemplifies the robust. He comes out a bit heftier than other T. rex specimens.”
“Scotty is the oldest T. rex known,” said Dr. Persons, first author of a paper published in the journal Anatomical Record.
