Since it was first described in 1905, "T. rex" has become the most widely recognized dinosaur species in popular culture. It is the only dinosaur that is commonly known to the general public by its full scientific name (binomial name) and the scientific abbreviation "T. rex" has also come into wide usage. Robert T. Bakker notes this in "The Dinosaur Heresies" and explains that, "a name like "T. rex" is just irresistible to the tongue."
