When & Where

The discovery of the Microraptor was highly unusual. At a press conference held by National Geographic in 1999, a new genus named Archaeoraptor was unveiled. However, the fossil in question was a chimera, meaning it was an assembly of elements from different species. Paleontologist Xu Xing described the tail remains from the forged fossil as belonging to a new species, giving it the name Microraptor zhaoianus.

Size & Weight

An adult Microraptor could reach a length of 77 centimeters and weighed around 1 kilogram. They are one of the smallest non-avian dinosaurs known. The Microraptor was also one of the first non-avialan dinosaurs discovered with the impressions of feathers and wings.

Mobility & Diet

Despite the popular misconception, there’s evidence showing that the Microraptor couldn’t fly. Their legs lacked the muscles for a ground take-off, so the Microraptor resorted to gliding, covering over forty meters in one undulating glide. Their carnivorous diet consisted of mammals, birds, and fish. However, unlike its close relative, the Anchiornis, the Microraptor likely didn’t have gastric pellets.

Interesting Points
