The most radical shakeup of the dinosaur family tree in a century has led scientists to propose an unlikely origin for the prehistoric beasts: an obscure cat-sized creature found in Scotland.
The analysis, which has already sparked controversy in the academic world, suggests that the two basic groups into which dinosaurs have been classified for more than a century need a fundamental rethink. If proved correct, the revised version of the family tree would overthrow some of the most basic assumptions about this chapter of evolutionary history, including what the common ancestor of all dinosaurs looked like and where it came from.

A fearsome dragon was featured in medieval Scandinavian and Germanic legends about the hero Sigurd/Siegfried. The story is the centerpiece in the epic saga Niebelungenlied, in which the Siegfried kills Fafnir, who had been transformed into a hideous dragon by a powerful curse.
In the legend, Fafnir guarded a hoard of golden treasure. The dragon was so huge that the very ground shook when he walked. At Drachenfels (“Dragon Rock”), Konigswinter on the Rhine, a large statue of a typical dragon lurks near the ruins of a castle built on the summit of the hill in about 1150. A cave below was believed to be Fafnir’s lair.
According to the story, the hero Siegfried tracked the Dragon to his lair, by following a trail of the dragon’s enormous footprints sunk deep in the earth.
Notably, conspicuous fossil trackways of two types of massive dinosaurs are found in Germany. In 1941, the German paleontologist H. Kirchner speculated that observations of Triassic dinosaur tracks in sandstone near Siegfriedsburg in the Rhine Valley of western Germany might have been the inspiration for the legend about the dragon Fafnir’s footprints.
