Troodon was a meat-eater the size of a man, with a brain as big as an avocado pit. It was not only the smartest dinosaur, but the smartest animal of dinosaur times, including our ancestors — the mammals of the Mesozoic Era.

Is the Raptors the smartest dinosaur?
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.
What was the least intelligent dinosaur?
The Least Intelligent Dinosaurs:
The primitive dinosaurs belonging to the group sauropodomorpha (which included Massospondylus, Riojasaurus, and others) were among the least intelligent of the dinosaurs, with an EQ of about 0.05 (Hopson, 1980).
Were there any intelligent dinosaurs?
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 is the fastest dinosaur that ever lived?
A: The fastest dinosaurs were probably the ostrich mimic ornithomimids, toothless meat-eaters with long limbs like ostriches. They ran at least 25 miles per hour from our estimates based on footprints in mud.
Which dinosaur is still alive?
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.
What was the first dinosaur?
For the past twenty years, Eoraptor has represented the beginning of the Age of Dinosaurs. This controversial little creature–found in the roughly 231-million-year-old rock of Argentina–has often been cited as the earliest known dinosaur.
What were the fastest dinosaurs?
The Fastest Running Dinosaur
The speediest dinosaurs were the ostrich mimic ornithomimids, such as Dromiceiomimus, which could probably run at speeds of up to 60 kilometres per hour.
What dinosaurs had 500 teeth?
Nigersaurus, you might remember, we named for bones collected on the last expedition here three years ago. This sauropod (long-necked dinosaur) has an unusual skull containing as many as 500 slender teeth.
Did Velociraptors actually exist?
Velociraptors were actually feathered animals. They grew up to 100 pounds, about the size of a wolf. And they likely hunted solo—using their claws to clutch rather than slash prey—when they roamed central and eastern Asia between about 74 million and 70 million years ago, during the late Cretaceous period.
What animal has the biggest brain?
The sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms).
How many hearts did dinosaurs have?
Most coldblooded animals, such as reptiles, have three chambers that mix the blood and send less concentrated oxygen to the body. The discovery of a dinosaur fossil with a four-chambered heart suggests that it was warmblooded. Here is a comparison of a human heart and a typical reptilian heart.
Are humans related to dinosaurs?
We and dinosaurs share body plans based upon four limbs. Although our skeletons have been modified in different ways, we have many of the same types of bones (the bones of our limbs and hands are a good example), and this all goes back to our swamp-dwelling common ancestor almost 400 million years ago.
Did dinosaurs evolve into humans?
No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
How come Dinosaurs were so big?
Paleontologists don’t know for certain, but perhaps a large body size protected them from most predators, helped to regulate internal body temperature, or let them reach new sources of food (some probably browsed treetops, as giraffes do today).
