Gorgosaurus libratus v Rajasaurus narmadensis

Gorgosaurus libratus
Gorgosaurus is a genus of tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period, between about 76.5 and 75 million years ago. Fossil remains have been found in the Canadian province of Alberta and possibly the U.S. state of Montana. Paleontologists recognize only the type species, G. libratus, although other species have been erroneously referred to the genus. Like most known tyrannosaurids, Gorgosaurus was a bipedal predator weighing more than a metric ton as an adult; dozens of large, sharp teeth lined its jaws, while its two-fingered forelimbs were comparatively small. Gorgosaurus was most closely related to Albertosaurus, and more distantly related to the larger Tyrannosaurus. Gorgosaurus was smaller than Tyrannosaurus or Tarbosaurus, closer in size to Albertosaurus and Daspletosaurus. Adults reached 8 or 9 meters (26 to 30 ft) from snout to tail. Paleontologists have estimated full-grown adults to weigh more than 2.4 tonnes (2.7 short tons). The largest known skull measures 99 centimeters (39 in) long, just slightly smaller than that of Daspletosaurus.

Rajasaurus narmadensis
Rajasaurus was an abelisaurid, a member of a group of theropod predators known to have lived only on landmasses that were part of the supercontinent Gondwana, such as Africa, India, Madagascar, and South America. Rajasaurus closely resembles Majungasaurus, a contemporary abelisaur from Madagascar, an island that had separated from the Indian landmass about 20 million years earlier.[4] It was found to be an abelisaurid through a phylogenetic analysis of anatomical characteristics, and was described as a carnotaurine abelisaurid (the subfamily including Carnotaurus) because of the configuration of its nasal bones and its possession of a growth ("excrescence") on its frontal bone. Rajasaurus is distinguished from other genera by its single nasal-frontal horn, the elongated proportions of its supratemporal fenestrae (holes in the upper rear of the skull), and the form of the ilia (principle bones of the hip) which feature a transverse ridge separating the brevis shelf from the hip joint. Rajasaurus was identified from a partial skeleton including a well–preserved skull (with a complete braincase and 70% of the rest of the skull bones recovered), hip bones and parts of the hind legs, backbone and tail. This specimen, GSI 21141/1–33, serves as the type specimen of the genus and species. Rajasaurus measured about 7.6–9 m (24.9–29.5 ft) long, 2.4 m (7.9 ft) in height, and weighed about 3 to 4 tons. The skull was short, measuring 60 cm (23.6 in) in length, and bore a distinctive low rounded horn. This horn is made up of outgrowths from the nasal and frontal bones.

After reading that, rajasaurus strikes 3 times, while Gorgosaurus simply opens the mouth. It's too dumb slow for Rajasaurus.

This is not going to be hit and run and as a Hadrosaur hunter, Gorgosaurus can't have been that slow and dumb (Hadrosaurs are believed o be quite fast)
Look:

Maybe that was a scavenged one, but Gorgosaurus is believed to prefer Hadrosaurs as prey item:

You are too dumb to writing any senseful post :angry:

Give me one argument that Gogosaurus is slow.
You realize I'm joking right?

Rajasaurus still has a little advantage.

Size for example.

I don't trust such sources, because their weights aren't based on real method, they just suggest it and take something what they think is realistic for it. Even wiki is a better source.

Almost every paleontologists agree that Allosaurus would win against Ceratosaurus is most fights. Only Allosaurus haters and Ceratosaurus fanboys disagree.
At least Ceratosaurus would have very good chance against Marshosaurus and Stokesosaurus.

Most serious Paleontologists don't debate about such things.

As far as the evidence go, Tyrannosaurids don't strike very slow like people believe

I think anyone who knows about dinosaurs would agree that allosaurus would win against ceratosaurus. But I would favour ceratosaurus over allosaurus at parity anyday.

rajasaurus is more robust and powerful when compared to a relatively gracile tyrannosaur such as gorgosaurus. the abelisaur wins 60% of the time.
