Greenwich Park was transformed into Jurassic Park this morning - with the arrival of a dead dinosaur on a truck.
The T-Rex had already stunned Londoners when it was driven around the streets yesterday near Trafalgar Square and London Bridge.
Despite being covered in a white sheet, the Tyrannosaurus' fearsome head could clearly be seen.
And this morning it was south east London's turn, as the creature was spied in Park Row and later in the town centre.
However, there's a perfectly reasonable explanation for the sighting - it was all a stunt by National Geographic TV for their upcoming T-Rex Autopsy show.
