It turns out the king of the dinosaurs actually shares a surprising amount of DNA with modern day chickens! In fact, birds are commonly thought to be the only animals around today that are direct descendants of dinosaurs.

How smart were velociraptors, really??? Velociraptors were Dromaeosaurids, among the dinosaurs with the very highest level, so they were truly smart among dinosaurs. On this ranking, they were probably a bit smarter than rabbits and not quite as smart as cats and dogs.

Velociraptor (/vɪˈlɒsɪræptər/; meaning “swift seizer” in Latin) is a genus of dromaeosaurid theropod dinosaur that lived approximately 75 to 71 million years ago during the latter part of the Cretaceous Period. Two species are currently recognized, although others have been assigned in the past.

‘There’s a weird urban myth that Velociraptor has a higher encephalisation quotient than humans. It clearly doesn’t. ‘However, the size of Velociraptor’s brain in proportion to its body is relatively high compared to most reptiles, including most other dinosaurs, so it seems likely it was comparatively clever.

Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.

Troodon had a large brain for its relatively small size and was probably among the smartest dinosaurs. Its brain is proportionally larger than those found in living reptiles, so the animal may have been as intelligent as modern birds, which are more similar in brain size.

According to Steven Stanley, a paleontologist at the University of Hawaii at Manoa, T. rex arms were used to slash prey in close proximity to the dinosaur. And the short arm length was actually more beneficial for slashing, considering the size of T. rex’s head.

This species, Lambe reported, had only two fingers. What’s more, according to Lambe’s analysis, the structure of its hand could not support a third digit at all. Since the arms of Gorgosaurus were unusually small and disproportionate to its body, like those of T.

T. Rex males mainly used their arms and hands to grab onto females during mating (females still possessed these limbs, of course, presumably using them for the other purposes listed below). T. Rex used its arms to clutch tightly onto squirming prey before it delivered a killer bite with its jaws.

As fearsome as Carnotaurus looked, though, it’s hard not chuckle at the dinosaur’s arms—the hand and lower part of the forelimb were so reduced in size that some paleontologists have viewed them as vestigial structures that have almost entirely lost their ability to function in acquiring prey.

It begins to charge the humans but the T. rex of Isla Nublar intercepted and pinned it down during the chaos, killing the Carnotaurus in the process. The T. rex then knocks over the Carnotaurus with her head and the Carnotaurus gets up and runs off.

Indominus rex is a fictional cross between a T. rex and a velociraptor that’s genetically engineered by scientists in the movie. Since it was a “made dinosaur,” according to Horner, there are no standards of accuracy for it to live up to.

Carnotaurus is a derived member of the Abelisauridae, a group of large theropods that occupied the large predatorial niche in the southern landmasses of Gondwana during the late Cretaceous.

Looking at the overall structure of the head and neck, the Carnotaurus could have used its horns for ramming. And these creatures gored each other during courtships, where male sparred against their rivals. Other studies suggested that Carnotaurus pushed against each other rather than delivered head blows like rams.

Carnotaurus was one of the fastest theropods thanks to its very long hind legs equipped with strong muscles that were connected with long, muscular tail.

A typical Allosaurus is 8.5–9 meters and 1.4–2 tonnes. It’s bigger and stronger, has a more fearsome set of jaws and teeth, and arms that can actually be used. Carnotaurus has no advantage besides speed which won’t help it too much.

In spite of allosaurus predating tyrannosaurus by millions of years, significantly more allosaurus specimens have been found. Both were bipedal dinosaurs but the T. Rex was larger and significantly heavier. Rex had very short forelimbs (arms) while the allosaurus had longer arms.
