Teeth of Spinosaurus aegyptiacus

Spinosaurus (colloquially also "Spino") refers to a dinosaur genus of which only the species"Spinosaurus aegyptiacus"is known. Translated, her name means "Egyptian Thorn Lizard". She became after herDiscovery site in Egyptnamed, and the1912first bones this kind ofErnst Stromer von Reichenbachwere discovered. There were other individual finds that are attributed to the "Spinosaurus maroccanus". However, this species has not yet been recognized due to the lack of bones.

From there, there were more finds of the carnivore that evenlarger than the Tyrannosaurus Rexis. During World War II, these finds were destroyed in one night and the Spinosaurus became oneunexploredLegend.

There were still some isolated finds of the mysterious dinosaur, but firstin 2014was aalmost complete skeleton findmade public, which finally provided more information about the Spinosaurus. His style turned out to be one of the most intriguingDinosaur Speciesout that was ever found.

Because the Spinosaurus is the only two-legged carnivore that lived, among other things, in the water and hunted there. HisLifestyle is comparable to that of a crocodileor hippopotamus. However, he belongs to the sameClassification of theropodslike a tyrannosaurus or allosaurus. It is only distantly related to marine dinosaurs. That's what makes him so special.

The Spinosaurus is considered the largest carnivorous dinosaur

In this chapter you will find everything you need to know about the Spinosaurus. We have compiled eight of its most important characteristics for you. These include, for example, hisgenusandclassificationwithin the dinosaur species.

You will also learn when and how the largest carnivore lived, how itsanatomywas and how he hunted. Afterwards we have a profile of the Spinosaurus with the most important data such asWeight,habitatandSizeat a glance.

Genus and Classification

The dinosaur species can be divided into two classes: the lizard-faced dinosaurs (Saurischia) and the bird-faced dinosaurs (Ornithischia). The Spinosaurus falls into the class ofEchsenbeckensaurier, more precisely in one of its subclasses: the theropods.

Theropodenare commonlyCarnivores that walk on two legs. They can also be divided into further subgenera. Spinosaurus belongs to the Spinosauridae subgenus. The Tyrannosaurus Rex, for example, is counted among the Coelurosauria.Spinosauridaeusually have onecrocodile skulland a so-calledback sail.

Although it lived partly in the water, hunted there and was a good swimmer, it is not directly related to the marine dinosaurs. Its fondness for water makes it unique among all theropods.

When the Spinosaurus lived

The Spinosaurus aegyptiacus livedabout 113 to 94 million years ago at the time of the Cretaceous. It can be divided into Lower Cretaceous and Upper Cretaceous. The robber lived in the transition from the Lower Cretaceous to the Upper Cretaceous. The exact time periods are given asalbium(112.9 to 100.5 million years ago) andCenomanium(100.5 to 93.9 million years ago).


Dinosaur researchers (palaeontologists) have not yet agreed on the habitat of the Spinosaurus. However, it is assumed that he is in amud flats in today's North Africalived. The first skeleton was found in 1912 near theBahariyya-Oase in Egyptfound.

The habitat of the dinosaur

The Spinosaurus lived there together with similarly large onescarnivoreslike Carcharodontosaurus (translated: "sharp-toothed lizard") and thelong-necked herbivoresTitanosaurs, Paralititan and Aegyptosaurus.

He also shares the habitat with the 10 meter longCrocodileStomatosuchus and a 3.5 meter longQuastenflosser. More bones were found inMorocco, Niger, Tunisia and Algeriafound. So its main habitat was what is now Africa.

Life expectancy

How old a Spinosaurus gotcould not be clearly clarified so far. However, a 30-year-old Tyrannosaurus Rex skeleton has already been found. So it could be that the Spinosaurus lived a similar age, since it was similar in size to the T-Rex and also belongs to the theropod genus.

physique and posture

The most distinctive feature of the Spinosaurus is itsback sail. It consists of elongated spinous processes on the back connected by skin. spinous processes areextensions of the vertebrae, which often protrude as humps in dinosaurs.

Researchers are not yet in agreement about the function of this sail. It probably served toCommunicationwith conspecifics (e.g. when displaying behavior) or the regulation of body temperature.

The body's center of gravity is further forward than, for example, with the T-Rex. Therefore, researchers assume that the Spinosaurusmoved mostly on four legshas. This posture is particularly suitable for paddling in the water.

Maybe he had toowebbed feetbetween the toes of the hind legs. As with many theropods, the hind legs were more powerful than the front legs. With its flexible tail, the dinosaur could also glide through currents.

Spinosaurus weight and size

The Spinosaurus is consideredlargest predatory dinosaur discovered to date. Estimates are he was4.5 meters high, 16 to 18 meters longand weighs between 6 and 20 tons. Researchers gave different estimates that changed over time. Probably oneWeight from 7 to 9 tons. His dorsal sail and his skull alone were each at least 1.7 meters long.

lifestyle and diet

Here the Spinosaurus catches an Onchopristis

It is assumed that the Spinosaurus hunted in the water andmainly fishate. On the menu here, for example, was the extinctOnchopristis, which looked a lot like a sawfish.

In addition, its long, pointed teeth, which are ideal for grasping slippery prey, speak in favor of eating fish as its main food. Added to this is its narrowcrocodile-like snout, which lends itself well toto catch fish in the water.

Seineclaws and armsare not large in relation to the rest of its body, but significantly larger than, for example, the T-Rex. With them, the Spinosaurus couldgrab caught fishto eat him. Hisoverhead nostrilsalso suggest that he could swim.

In addition to fish, the water-loving dinosaur probably hasalso eats meat. This is supported, for example, by a severed tooth that was found in a pterosaur and evidence of its close relative "Baryonyx" (family Spinosauridae), in whose digestive tract both fish and meat remains were found.

hunting behavior and speed

Probablysnappedthe Spino with preferencein the water for fishand pterosaurs flying by, who also wanted to get hold of some fish. But one can assume that he tooon land to huntleft when an opportunity arose.

To catch fish with his snout or claws, he needed onegood response time. In the water he has his strongmovable tail driveawarded. Due to its rather heavy bones and stooped stature, it was probably not the fastest of its kind.

The Spinosaurus is often depicted because it looks so special. Even before the Second World War it attracted many visitorsMunchner Museum, in which his finds were exhibited.

Today, many know the dinosaur from its role in the filmJurassic Park III, in which he defeats a T-Rex or through thatSurvival-Spiel "ARK: Survival Evolved"for computers, PlayStation 4, Xbox One, Nintendo or as an app for Android and iOS.

Spinosaurus vs. T-Rex: Who is stronger?

T-Rex and Spinosaurus are considered the most dangerous and largest carnivores of the dinosaur age. TheT-Rexdid thatLanduncertain, whereas thespineon and inWaterhunted. People have therefore repeatedly asked themselves the question: What would have happened if the two apex predators had met? Who is stronger?

An advantage ofSpinosaurusare hislonger armsand its long pronounced claws. TheT-Rexhowever, has a verystrong biteand a stable neck. The Spinosaurus' power is distributed throughout its long body, while the Tyrannosaurus Rex embodies concentrated power. In addition, a T-Rex has stronger teeth and a strong bite force. Afull-grown T-Rex would probably have the better fighting conditions.

Either way, the two dinosaur species would never have met because theSpinosaurus lived more than 26 million years earlierhas than the T-Rex. Below we have a table for you that compares the fighting characteristics of the two predatory dinosaurs.

Spinosaurus extinction

Spinosaurus: profile + 8 characteristics of the dinosaur » writing.net (7)

Spinosaurus extinction

The first species of dinosaurs appeared on Earth about 245 million years ago. At the beginning of their reign, the continents were not yet separated by the sea and formed a contiguous land area ("Pangaea").66 million years agothen it came toExtinction of the Dinosaurs. At that time he wasSpinosaurus already extinct.

Researchers assume that he is aboutlived until 94 million years agohas. His living conditions have probably changed due to the climate, natural disasters or other circumstances, so that he could no longer survive. Nevertheless, he hasSpinosaurusin approximatelylived on our earth for 19 million years- much longer than we humans.

Many scientists still assume that the dinosaurs were killed by ameteorite impact, severalvolcanic eruptionsor both died. However, there is no irrefutable evidence for this. Another theory is the fastdrop in sea level.

DieEarth is already 4.6 billion years old. The dinosaur extinction is one of five mass extinctions in the last 550 million years. Despite the extinction of the giant lizardsbirdlike dinosaurs and mammals continued to survivebecame the dominant land animals. Today's birds and crocodiles are also descended from dinosaurs.
