Alectrosaurus: A Small But Powerful Feathered Dinosaur

Throughout the years, dinosaur studies have revealed many fascinating facts about these extinct creatures, none more intriguing than the small, feathery Alectrosaurus. This small dinosaur packs a powerful punch in spite of its diminutive size, and it is considered one of the most important discoveries within the dinosaur community.

An early element of its story was its discovery. Back in 1992, paleontologist Li Yumin was digging at the Changma Basin in the Gobi desert of China. He uncovered a well-preserved Alectrosaurus, consisting of a partial skeleton of bones, including some well-preserved tail feathers. Yumin’s find was remarkable for two reasons. One, it was the first feathered dino ever discovered and two, despite being a relatively small species, it dwarfed even the biggest bird skeletons.

Alectrosaurus: A Brief Description

The Alectrosaurus was a small, feathered dinosaur belonging to the dinosaur group known as theropods. Theropods typically had long hind legs and short forearms, with some members of the group even featuring feathers. The Alectrosaurus was a bipedal, ground-dwelling creature that could easily have reached speeds approaching 16 miles per hour, even while covered in feathers. It was a carnivore, feeding primarily on small animals and insects, although some specimens have been found with remains of larger prey such as lizards and small amphibians. In comparison to other theropods, the Alectrosaurus was about as small as it gets, measuring approximately three feet in length and having a stature of about two feet tall.

Alectrosaurus: A Magnificently Feathered Creature

A true standout element of the Alectrosaurus was its feathers. These tiny feathers were spread all along the body, from the tail down to the tips of the feet. Scientists have estimated that the Alectrosaurus was covered in up to 2,000 feathers at any given time, although it is possible that the actual number may have been larger.

The feathers themselves were Vaned feathers, meaning that they possessed a stem or rachis and a pair of vanes coming off either side. These feathers were primarily thought to be for insulation, although some believe that they may have contained trace amounts of color for the purpose of communication and attraction, as we see with birds today.

Alectrosaurus: An Important Find in Dinosaur Studies

The Alectrosaurus is an extremely important find in the field of dinosaur studies. Before its discovery, there was no evidence of feathered dinosaurs beyond drawings and speculation. Its discovery opened up a whole new field of paleontology and revealed many truths about the ferocity of dinosaur species.

The Alectrosaurus was one of the first confirmed feathered dinosaurs ever discovered, and its discovery has made it possible to uncover many more feathered dinosaurs. Furthermore, the feathers discovered on the Alectrosaurus suggest that other feathered dinosaurs not only existed, but that they may have been as powerful and dangerous as they were thought to be back in the days of myth.


The Alectrosaurus was a small feathered dinosaur that contained many clues to the evolution and development of dinosaurs. Its discovery opened up a whole new field of research for scientists and paleontologists and has enabled us to uncover the truth about these mysterious creatures. The Alectrosaurus may be small, but it was and still is instrumental in our understanding of ancient dinosaur behavior and ecosystems.
