Fossil hunters in Chile have unearthed the remains of a bizarre Jurassic dinosaur that combined a curious mixture of features from different prehistoric animals.
The evolutionary muddle of a beast grew to the size of a small horse and was the most abundant animal to be found 145 million years ago, in what is now the Aysén region of Patagonia.
The discovery ranks as one of the most remarkable dinosaur finds of the past 20 years, and promises to cause plenty of headaches for paleontologists hoping to place the animal in the dinosaur family tree.
“I don’t know how the evolution of dinosaurs produced this kind of animal, what kind of ecological pressures must have been at work,” said Fernando Novas at the Bernardino Rivadavia Natural Sciences Museum in Buenos Aires.
