That's right he's been usurped. Kicked to the curb. A nobody.
In Patagonia a farmer saw a bone sticking out of the dirt that 'didn't look right'. The paleontologists came and discovered the jack pot. A never before seen dinosaur that eclipsed T. rex. It's similar, only THREE TIMES LARGER.
It's estimated that the unnamed(Titantasaur?) saur-puss stood seven stories tall and dragged a tail(counter-weight) that brought his length up to 10 stories. He hit the scales at 160,000lbs or about 77 US tons - two maxed out semis.
Talk about ground tremors! (remember those from Jurassic Park before the lawyer got et?)
I believe they found the bones of 6 of them and about 50 teeth. They're already building a museum to house the bones and support the inevitable dino tourism.
