Did some dinosaurs have 2 Hearts?
There’s no evidence that dinosaurs of any sort had bizarre accessory hearts, but the idea has still played a small role in the ongoing investigation into how giant dinosaurs actually lived. To start, we have to go back to ancient bones and the ways in which paleontologists put them together.
Which dinosaur had the biggest brain?
Troodontids (formerly Saurornithoidids) were remarkable in having the largest brain-to-body size ratio of all non-avian dinosaurs, possibly making them the most intelligent dinosaurs on a level with the smartest birds.
Did T. rex have a brain?
An adult Tyrannosaurus rex had a brain that weighed approximately 1 kilogramme, about half of the size of an adult humans but that does not mean that T. rex was half as smart as we are – the size of the body and the arrangement of the functions in the brain have to be considered.

What dinosaur is the smartest?
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.
What animal has 32 brains?
Leech has 32 brains. A leech’s internal structure is segregated into 32 separate segments, and each of these segments has its own brain. Leech is an annelid.
Do dinosaurs Still Exist?
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.
Are Raptors smarter than humans?
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.
What dinosaur has 8 hearts?
A dinosaur that lived some 200 million years ago may have had eight hearts to pump blood up to its head, said scientists writing in the latest edition of the British medical journal The Lancet.
Did dinosaurs have 3 or 4 chambered hearts?
Scientists have found the first fossilized dinosaur heart, and it appears to have four chambers, perhaps the strongest indication yet that dinosaurs were warmblooded animals, like birds and mammals.

What dinosaur has the smallest brain?
Stegosaurus: the dinosaur with the smallest brain.
Why did dinosaurs have such small brains?
While the dinosaurs grew bigger, their brains didn’t keep up. By the time the sauropods, like brontosaurus, reached 100 tons and 110 feet long, their brains were only the size of tennis balls. Thi sfeature is strange because usually, evolution favors larger brains over time.
What animal has 25000 teeth?
Snails: Even though their mouths are no larger than the head of a pin, they can have over 25,000 teeth over a lifetime – which are located on the tongue and continually lost and replaced like a shark!
What animal never dies?
To date, there’s only one species that has been called ‘biologically immortal’: the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
What animal has longest lifespan?
The Greenland shark has the longest known life span of all vertebrates, estimated to be between 300 and 500 years. Found in the North Atlantic and Arctic Oceans, the species can reach an astonishing 21 feet in length and mostly eats fish, but has been spotted hunting seals.
What animal has 300 teeth?

Will dinosaurs come back in 2050?
The answer is YES. In fact they will return to the face of the earth in 2050. We found a pregnant T. rex fossil and had DNA in it this is rare and this helps scientists take a step closer of animal cloning a Tyrannosaurus rex and other dinosaurs.
Do dinosaurs pee?
The question is whether non-avian dinosaurs expelled their solid and semi-solid waste together, like many birds, or they urinated and defecated separately as ostriches and crocodylians can. The traces found so far hint that at least some dinosaurs urinated. Whether all non-avian dinosaurs did so isn’t clear.

Why does octopus have 3 hearts?
2) Octopuses have three hearts. Two of the hearts work exclusively to move blood beyond the animal’s gills, while the third keeps circulation flowing for the organs. The organ heart actually stops beating when the octopus swims, explaining the species’ penchant for crawling rather than swimming, which exhausts them.
Is crocodile a dinosaur?
Crocodiles are not dinosaurs, but both crocodiles and dinosaurs came from the crown group Archosaurs. Archosaurs were reptiles that included birds, crocodiles, pterosaurs, and dinosaurs. Modern-day birds are descendants of feathered dinosaurs, evolving over the last 65 million years.
Are velociraptors dumb?
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.
Why do octopus have 9 brains?
Octopuses have 3 hearts, because two pump blood to the gills and a larger heart circulates blood to the rest of the body. Octopuses have 9 brains because, in addition to the central brain, each of 8 arms has a mini-brain that allows it to act independently.
How big is a Barosaurus?
Do giraffes have 2 hearts?
Three hearts, to be exact. There is a systemic (main) heart. Two lesser hearts pump blood to the gills where waste is discarded and oxygen is received. They work like the right side of the human heart.
Which animal blood is black?
Brachiopods have black blood. Octopuses have a copper-based blood called hemocyanin that can absorb all colors except blue, which it reflects, hence making the octopus’ blood appear blue.
Can a person have 2 hearts?
Aside from conjoined twins, no human is born with two hearts. But in the case of extreme heart disease, called cardiomyopathy, rather than receiving a donor heart and removing yours, doctors can graft a new heart on to your own to help share the work. This is more commonly known as a piggy-back heart.
Did T Rex have color vision?
Sight: T. rex had an eye about the size of a softball, one of the largest eyes ever developed in the animal kingdom – past or present. This would have included plenty of space for black-and-white and color receptors; since its ancestors (crocs) and its descendants (birds) see in color, scientists think T. rex did, too.
Did T Rex have a hole in hip socket?
While these animals lived alongside dinosaurs, they did not have a hole in their hip socket and thus were not dinosaurs. Modern birds are one kind of dinosaur because they share a common ancestor with nonavian dinosaurs.
Could T rex have had feathers?

How do scientists know how smart dinosaurs were?
One Measure of Dinosaur Intelligence: EQ
The Encephalization Quotient, or EQ, measures the size of a creature’s brain against the size of the rest of its body and compares this ratio to that of other species of roughly the same size.
How smart were Trexes?
rex. By calculating the ratio of brain size to body size as a measure of intelligence (modern day animal scientists use this ratio as an approximation), we can infer that the T. rex about matches a chimp on smarts, and was quite a bit keener than a pet cat or dog.
