The size is not everything. Deinonychus antirrhopus is an example of this. The seventh supersaurus in the superlative series was only ten feet tall, but it was one of the most dangerous and intelligent dinosaurs to ever walk on earth.
Inhabitant of what is now known as North America, the Deinonychus lived about 110 million years ago. When it moved agilely on two legs, it used its flexible tail for balance. The jaws of the Deinonychus, with their many jagged-edged teeth, were very similar to those of a carnivore. Despite having a large enough brain to suggest that it was a highly intelligent animal, its skull was relatively narrow. This allowed the Deinonychus to see stereoscopically and estimate distances accurately, an essential requirement for a successful predator. But perhaps the most striking feature of Deinonychus was the large sickle-shaped claws on the second toe of its hind legs.
This coin and all those in the series have the peculiarity that they have been colored with special inks that make the silhouette of the animal represented in the piece glow in the dark. This time the piece shows a Deinonychus printed in color in the company of a Xenoceratops. The Austrian Mint has officially issued this seventh piece on June 16.
On the obverse of the coin, common to the entire series, the silhouette of the 12 prehistoric animals that make up the Supersaurus series is represented.
