The Lambeosaurus was a genus of dinosaurs that inhabited the planet during the Cretaceous period (about 83 million years ago). It is a specimen that has been classified within the group of the dinosaurs ornitisquios hadrosauridos.

This genus would have used all four extremities to move around, nothing out of the ordinary if it was not also capable of standing on two legs to adopt an upright position.

The most striking feature of the Lambeosaurus was undoubtedly the hollow, axe-like crest on its skull. This ridge would only have served as a sex appeal for the male specimens.

History of Lambeosaurus

Its name has a quite obvious meaning, “lambe length”, in honor of Lawrence Lambe, was a specimen whose diet was based on the consumption of vegetable food and used the four limbs it had to move from one point to another, it is also known that this extinct specimen could use its two hind limbs to stand up, depending on the situation in which it needed to do so.

On the other hand, another of the striking characteristics of the specimen was the protuberance that it possessed in the skull, a structure in the shape of a crest, which gave it a lot of differentiation from the rest of specimens of its time, this structure had the shape of an axe but at the same time it is known that inside it had nothing, it was totally hollow.

The initial vestiges were found with much fortune in the Canadian province of Alberta, also a city identified as Montana, within the United States of America, without forgetting to mention a group of remains that were found in the zone of Baja California, although really this last group is not taken into account in a valid way, for a series of reasons.

A great researcher of prestige identified as William Parks was in charge of the complicated review of this animal, precisely in the 1920’s, which managed to focus the attention of other scientists again on this dinosaur, due to the fact that for 20 years since that date, no researcher had taken the trouble to reanalyze the origin, behavior and other details of the Lambeosaurus.
Like the vast majority of these extinct animals, the history of their taxonomy is not easy to describe or document. This is due to the fact that there were some small specimens similar to the Lambeosaurus, which were initially confused with it, but were later assigned to another genus with good reason.

One of the dinosaurs that was closely related to the Lambeosaurus was identified as Corythosaurus, which from the beginning was also confused with it, but later it was concluded that they were very close relatives, all because the remains were found in the same place but on rocks from different periods.

Both specimens had a strange ridge that had not been seen or studied in other past specimens, so it was quite easy to fall into confusion and make mistakes, however, after a few years came to know the functions of these crests: they served to display and show their courage to the females and even to other specimens of their own species.

Characteristics of the Lambeosaurus

If we now begin to buy the dinosaur known as Corythosaurus with the dinosaur that is the subject of this article, we will see that there are also recognizable differences even in the shape and position of its crests, due to the fact that the crest of the first animal mentioned was in a position that seemed to point towards the front of the individual, which also had a smaller spine that pointed towards the front of the animal, while the Lambeosaurus did not have these characteristics.

Another known quality of this animal is that its ridge changed shape and size according to its level of development or age, as well as according to its sex, as we see today in contemporary animals with crests.
Another detail not minor about this specimen is that the bone structure of its nose was also distributed within this protuberance that we call crest, so it is assured that this fact achieved that the animal had a sense of smell much more developed and refined.

On the other hand, if we continue to look for similarities between this animal and other specimens, we can clearly state that it was very similar to other specimens identified as hadrosaurs, which also had the capacity or ability to move using two or four of their extremities, just as the Lambeosaurus does.

If we continue to observe this animal slowly, we will notice that its curious tail was made up of a group of tendons that were formed by resistant bone tissue, a detail that gave it a lot of rigidity and in fact prevented this part of the animal from crawling.

As for his hands, we can say that he was missing one of the fingers that we humans consider basic for survival: the thumb, because they did not need it, the other fingers were enough to perform any kind of function.

Finally we arrive to the most interesting part of the article, in which we mention that the maximum size that this animal could have reached is almost 10 meters long, meanwhile, we can also observe some elements known as scales, which we can also observe in other specimens of the same family, these scales can be found basically in areas such as the neck and tail, and in a smaller amount in the part of the torso.

It is also known that its speed could have been a fundamental factor in its survival when faced with other large predators, since thanks to recently found footprints it has been possible to know that it was an animal that travelled long distances without any kind of problem.

In fact, it was something it did in order to take advantage of other specimens of its time, both to avoid running away and to be able to obtain food in good condition that would allow it to continue developing and expanding its species.

At the beginning this animal was called Trachodon marginatus, a detail that gives us a summary of the fact that its classification has not been and will not be peaceful, all this began right at the beginning of the 20th century, when Lawrence Lambe himself made the first review of the animal.
