Its fossils are known from the Romualdo Formation. Irritator had straight and cone-shaped teeth. Irritator's name comes from the English word "Irritation". It was given its name due to the feelings of the scientists who described it when they found that fossil dealers had added plaster to the front of the snout.

Similarly, it is asked, what does Irritator mean?

Irritator (meaning "Irritating") was a genus of spinosaurids, living during the early Cretaceous Brazil. It is estimated to be around 7.9 meters (26 feet) in length and around 1 metric ton. The only known species is Irritator Challengeri.

Is T Rex an animal?

Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it is still among the largest known land predators and is estimated to have exerted the strongest bite force among all terrestrial animals.

Where was Irritator found?



What does Ostafrikasaurus mean?

The specific name is derived from the Latin crassus, meaning "thick"; and serratus, meaning "serrated", in reference to the large serrations of its teeth. MB R 1084 differs in several respects from the other eight teeth found in the Middle Dinosaur Member.

Is irritation a real dinosaur?

Irritator is a genus of spinosaurid dinosaur that lived in what is now Brazil during the Albian stage of the Early Cretaceous Period, about 110 million years ago. It is known from a nearly complete skull found in the Romualdo Formation of the Araripe Basin.

Did Spinosaurus feathers?

And it is my understanding that not "all" dinosaurs are believed to have had feathers, but just theropods. Spinosaurus is classified as a theropod, so there is a distinct possibility that they had feathers. Since there are no known ancestors on Spinosaurus' family tree with feathers, no.

What did Irritators eat?

A generalist diet—like that of today's crocodilians—has been suggested; Irritator might have preyed mainly on fish and any other small prey animals it could catch. Fossil evidence is known of an individual that ate a pterosaur, either from hunting or scavenging it.

Is suchomimus bigger than baryonyx?

Gregory S. Paul, however, gave lower estimations of 9.5 m (31 ft) and 2.5 t (2.8 short tons; 2.5 long tons). The holotype of Suchomimus was considerably larger than that of Baryonyx, but the ages of the two individuals are not known.

Why did T Rexes have short arms?

The precise purpose of T. rex's relatively tiny arms has long been mysterious. Over the years, scientists have suggested that they might have been used to grasp struggling prey, to help resting dinosaurs push themselves up from the ground, or to grip tight to mates during sex.

Is suchomimus a baryonyx?

Baryonyx, a dinosaur which lived in the Barremian stage of the early Cretaceous Period. But another fish-eater, the Suchomimus, large theropod dinosaur with a crocodile-like skull that lived between 125–112 million years ago, appeared!

How tall is a suchomimus?

Suchomimus was 9.5 to 11 metres (31 to 36 feet) long and weighed between 2.5 to 5.2 tonnes (2.8 to 5.7 short tons), although the holotype specimen may not have been fully grown. Suchomimus's narrow skull was perched on a short neck, and its forelimbs were powerfully built, bearing a giant claw on each thumb.

What did suchomimus weigh?

Suchomimus was 9.5 to 11 metres (31 to 36 feet) long and weighed between 2.5 to 5.2 tonnes (2.8 to 5.7 short tons), although the holotype specimen may not have been fully grown.

What did suchomimus eat?

Suchomimus tenerensis (meaning "crocodile mimic from Tenere," after the part of the Sahara desert where it was found) was a fish-eating (and meat-eating) spinosaurid theropod dinosaur.

When did suchomimus live?

125 million years ago - 100.5 million years ago (Aptian - Albian)

Did suchomimus have a sail?

Suchomimus had a sail-like structure along its back, perhaps used for regulating its temperature. This sail captured heat in the cool mornings, giving the predator an edge on other cold-blooded animals. Also, in the sweltering heat of the Cretaceous afternoons, Suchomimus could dissipate extra heat through its sail.

Where was the Spinosaurus found?

Spinosaurus aegyptiacus remains were first discovered about 100 years ago in Egypt, and were moved to a museum in Munich, Germany. However, they were destroyed during World War II, when an Allied bomb hit the building.

What does a suchomimus look like?

Suchomimus ("crocodile mimic") was a spinosaurid dinosaur. "It was a dinosaur trying hard to be a crocodile," says paleontologist Paul Sereno after he discovered a Suchomimus tenerensis during an expedition to Africa. It had a long snout filled with teeth that seem designed to catch fish.
