Famous dinosaurs you can visit

In Steven Spielberg's blockbuster "Jurassic Park," the terrifying Spinosaurus and the T. rex met in a bloody battle. That was pure fiction. In reality, the two dinosaurs existed 40 million years apart from each other. The T. rex lived in North America; the Spinosaurus roamed Africa. A Spinosaurus skeleton was found several years ago in Morocco, but the one at the Berlin exhibition is a model.

The Spinosaurus, which lived 100 million years ago, was a unique dinosaur species. It lived in the water, ate fish as large as cars, and was able to chew its prey to pulp in its powerful jaws. The first Spinosaurus bones were discovered in 1912, but they disappeared in the chaos of World War II. Now the world's first life-sized skeleton model of the species is shown at the Museum für Naturkunde.

For the first time, dino fans can observe the Spinosaurus standing next to a T. rex - but only through June 12, when the Spinosaurus exhibit will close. The T. rex, known as "Tristan Otto" after the sons of its two owners, went on show in Berlin in December and will stay for three years. It is the only original skeleton of a T. rex in Europe to date and is one of only 50 reconstructions worldwide.

Because the real skull is too heavy for the 12-meter-long T. rex skeleton, it's displayed in Berlin's natural history museum in a separate case. A 3D printer was used to create the replica attached to the skeleton. The real skull is 1.5 meters long and 98-percent intact. In the last six weeks, 116,000 visitors have come to the museum to see "Tristan" before the Spinosaurus joined on February 9.

Forty meters long, 20 meters tall and weighing 80 tons - that's the probable size of the Stegosaurus that this bone belonged to. Discovered in Argentina in 2014, it is the largest dinosaur ever found. Since the skeleton was incomplete - unlike the T. rex now in Berlin - experts could only speculate over how large the Stegosaurus actually was.

Unlike the predatory dinos in Berlin, the Stegosaurus was a peaceful vegetarian. The most complete Stegosaurus skeleton - including 300 original bones - measures 5.6 meters and is on display at the Natural History Museum in London.

This Titanosaurus was set up in the American Museum of Natural History in New York. The bones, representing a nearly intact skeleton, were discovered by a German oil company while it was drilling in Argentina. The region in Patagonia in southern Argentina is considered a jackpot for paleontologists.
