Undoubtedly a dinosaur that is becoming more popular every day, although many times, due to the name it is often confused with the Allosaurus. Let’s learn a little more about this unique dinosaur. Keep reading.

What does the name Alioramus mean?

The name Alioramus specifically means “Different Branch“. Name derived from the Latin word’Remotus’, meaning’Sacado’. The Russian Sergei Kurzanov was responsible for this name in 1976.

History of the Alioramus discovery

The holotype consists of a partial skull and three intermediate bones. These remains were discovered in the Gobi desert; situated between northern China and southern Mongolia.

As we said before, the first one is to describe this finding was the Russian paleontologist Sergei Kurzanov, in 1970. According to Kurzanov’s description, the remains distinguished many from those of the Tyrannosaurus, so he ruled out that they belonged to this family.

In fact, the name refers to the fact that the Alioramus is part of a new branch parallel to the evolution of the Tyrannosaurid family. On the other hand, some experts claim that Alioramus may be related to tarbosaurus.

A second species was found in 2009 and named Alioramus altai, it was described by Brusatte.

When was he alive and what did he eat?

Like all theropods and from what was observed in the skull it had sharp teeth which suggest that its diet was mainly carnivorous.

To be more precise, the dimensions of their teeth and uniformity show that most of their prey were fast and defenseless. In addition, their narrow skulls denote a lower bite force than those of other Tyrannosaurids, so it can be concluded that they fed mainly on other soft-fleshed, unarmed dinosaurs.

As for when he lived, it is known that he lived in the Upper Cretaceous, about 75 to 70 million years ago, in what is known as the Campanian.

Alioramus description

Due to the little fossil evidence, it is very difficult to make a physical illustration of this dinosaur. But based on the fact that it was a theropod. We can suggest that he was bipedal and had sharp teeth.

It was smaller than other theropods such as the Tarbosaurus and Tyrannosaurus. And while it cannot be accurately estimated whether the skull found belongs to a young or adult species, there are many characteristics that suggest that it was a skull from a juvenile specimen.

According to Kurzanov’s estimates, he suggests that this dinosaur could measure between 5 and 6 meters in length. Although Kurzanov did not take other variables into account, so other researchers say it may have been larger. In addition, it should be noted that there is no evidence of an adult fossil, to be a more accurate estimate.

One of the most distinctive features of the Alioramus is that it has five ridges, approximately one centimeter high, running through the top of its muzzle.
