The dinosaur of the day: Alectrosaurus

Tyrannosaurid that lived in the Cretaceous in what is now Inner Mongolia, at the Iren Dabasu Formation

Only one species: Alectrosaurus olseni

Name means “Alone lizard”

Found in 1923 as part of the Third Asiatic Expedition of the American Museum of Natural History, led by Walter W. Granger

Named in 1933 by Charles Gilmore

Species name in honor of George Olsen, assistant paleontologist, who discovered the fossils, including a nearly complete right hindlimb, part of the right femur, tibia, fibular, toes, hand, and part of the pubis

Olsen also found a second specimen nearby (included humerus, fingers, vertebrae)

Other fossils have been referred to Alectrosaurus, found in China and Uzbekistan

Medium-sized, bipedal carnivore

Could grow up to 16.4 ft (5 m) long, and had a similar body shape to T. rex

One of the top predators of its time, along with Gigantoraptor

Probably preyed on ornithischians, such as Bactrosaurus and Gilmoreosaurus

Tibia and femur were similar in length (different from other tyrannosauroids, where the tibia is longer)

Also, the hind foot and ankle were closer in size to the tibia than other tyrannosauroids (hind foot is usually longer)

Some scientists have thought Alectrosaurus olseni was a species of Albertosaurus, but Carr in 2005 said Alectrosaurus had a number of distinguishing characteristics, and was its own genus

Fun Fact:

“odon” is historically one of the most common dinosaur name endings, but it is used much less often these days.
