Research on the olfactory bulbs has shown that T. rex had the most highly developed sense of smell of 21 sampled non-avian dinosaur species. [188] Cast of the braincase at the Australian Museum, Sydney. Somewhat unusually among theropods, T. rex had a very long cochlea. The length of the cochlea is often related to hearing acuity, or at least ...
Montana's T. rex (also known as "Peck's rex", "Peckrex", "Rigby's rex" and Tyrannosaurus "imperator") is the nickname given to a fossil specimen found in Montana in 1997. [54] The discovery was made by Louis E. Tremblay on 4 July 1997 working under the supervision of J. Keith Rigby Jr. who led the excavation and bone preparation.
When the preparation was complete in 2011, a ~65% complete T. rex skeleton was revealed. [ 2 ] Since its discovery and extensive subsequent study, Scotty has been referred to as the largest T. rex ever discovered in the world, the largest of any dinosaur discovered in Canada, and as one of the oldest and most complete fossils of its kind at ...
Previously discovered T. rex skeletons were usually missing over half of their bones. [10] It was later determined that Sue was a record 90 percent complete by bulk, [11] and 73 percent complete counting the elements. [12] Of the 360 known T. rex bones, around 250 have been recovered. [1]
Image differs appreciably from known skeletal elements. Example: A Deinonychus reconstructed with four fingers. Image differs appreciably from implied skeletal elements (via phylogenetic bracketing). Example: An oviraptorid known only from postcranial elements reconstructed with teeth, a feature made highly improbable by its phylogenetic position.
Theri comes from the same family as the T-rex and Giganotosaurus. If you saw the movie, you know what else went into the Indominous. Jurassic World set a record for the biggest opening weekend ...
