A Tyrannosaurus Rex named Rex is the main character and narrator. Other dinosaurs included in the book are a Triceratops, a Saurolophus, an Apatosaurus, a Stegosaurus, and a Dryosaurus, with the only exception being the Pteranodon, a pterosaur. A sequel book was later published, Going Hollywood!
The holotype was named as Tyrannosaurus bataar by Evgeny Maleev as Tyrannosaurus bataar. [7] The genus Tarbosaurus was also described in the same year based on PIN 551–2, a specimen with a skull and skeletal remains discovered by the same expedition in 1948 and 1949 as Tarbosaurus efremovi. [8]
The smallest known Tyrannosaurus rex individual (LACM 28471, the "Jordan theropod") is estimated to have weighed only 29.9 kilograms (66 lb) at only 2 years old, while the largest, such as FMNH PR2081 ("Sue"), most likely weighed about 5,654 kg (12,465 lb), estimated to have been 28 years old, an age which may have been close to the maximum for ...
This clade was defined by Sereno (1999) as "Tyrannosaurus rex, Passer domesticus (the house sparrow), their last common ancestor, and all of its descendants".

It is the only Tyrannosaurus specimen alongside MOR 980 (Peck's Rex) in which the mount includes the real skull fossilized bones. [17] Also some of the actual gastralia or belly ribs were used, which had been found in articulation with the remainder of the ribcage, allowing for a particularly realistic restoration of the thorax.
Tyrannosauroidea (meaning 'tyrant lizard forms') is a superfamily (or clade) of coelurosaurian theropod dinosaurs that includes the family Tyrannosauridae as well as more basal relatives.
