Poor little Hesperonychus elizabethae, only managed to hold onto it's title of North America's smallest dinosaur for less than a year. Now, a 'new' dinosaur (Fruitadens haagarorum) has eclipsed its record. When I say 'new', however, the creature was first discovered in the 1970s, but the specimens were never recognised as being adult dinosaurs due to their tiny sze.

Fruitadens haagarorum was just 28 inches (70 centimeters) long and weighed less than two pounds (one kilogram).

The diminutive dinosaur likely darted among the legs of larger plant-eaters such as Brachiosaurus and predators such as Allosaurus about 150 million years ago, during the late Jurassic period.

(Please note that the article mentions Albertonykus borealis as the revious record holder, but this is an error)
