Facts about Dinosaur. There are 19 facts & answers about Dinosaur
19. What is the youngest dinosaur?
Youngest Dinosaur Fossil Found in Montana: Giant Clue for Extinction Theory. A dinosaur fossil believed to be the youngest ever found was discovered by Yale scientists in Montana's Hell Creek formation, a study published in Biology Letters revealed. The 45-centimetre horn is understood to be from a triceratops.
18. Did any dinosaurs survive?
Part of the Dinosaurs: Ancient Fossils, New Discoveries exhibition. Not all dinosaurs died out 65 million years ago. Avian dinosaurs--in other words, birds--survived and flourished.
17. What killed the dinosaurs?
The asteroid impact led to the extinction of 75% of life, including all non-avian dinosaurs. The crater left by the asteroid that wiped out the dinosaurs is located in the Yucatán Peninsula. ... It is called Chicxulub after a nearby town.
16. How long does it take for a dinosaur to grow up?
These studies, done in conjunction with paleontologists at AMNH, document that that Tyrannosaurus, which attained a weight of more than 10,000 pounds as an adult, reached sexual maturity at about 20 years of age and lived for up to 28 years.
15. What is at Rex called?
The species Tyrannosaurus rex (rex meaning "king" in Latin), often called T. rex or colloquially T-Rex, is one of the best represented theropods. Tyrannosaurus lived throughout what is now western North America, on what was then an island continent known as Laramidia.
14. Do dinosaurs have 2 brains?
As paleontologists now know, no dinosaur had a second brain. There are two intertwined issues here. The first is that many dinosaurs had noticeable expansions of their spinal cords around their limbs–a feature that left its mark in the size of the neural canal in the vertebrae. This isn't unusual.
13. Do dinosaurs drink water?
They drink every few days and get most of their water from their herbivorous diet. "Maybe sauropods were able to gather enough water from all the plants they ate all day, too," suggested the University of Missouri's Holliday. A sensible plan for animals living the high life.
Sure enough, the fossil eggs from the ancient floodplain showed a different chemistry from those from the forest. Floodplain dinosaurs slurped from local rivers, while forest dinosaurs drank water rich in minerals that had circulated through the rocks, picking up volcanic salts on the way.
12. Do dinosaurs sleep?
Yes, dinosaurs did sleep. But, knowing exactly how they slept, whether they slept standing or laying, is not a question we can answer with certainty. Even though we have some fossils of dinosaurs said to be sleeping, we have to depend mostly on our knowledge of living animal sleeping habits.
11. What was last dinosaur?
For now, however, the 65-million-year-old Triceratops is the world's last known surviving dinosaur.
10. What's the fastest dinosaur?
ostrich mimic ornithomimids
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.
9. How long did a dinosaur live?
Early estimates of 300-year lifespans for the largest sauropods were based on comparisons with crocodiles and turtles, which have much slower metabolisms. The consensus is now that Apatosaurus and Diplodocus dinosaurs probably only lived for 70 or 80 years, which is about the same as an elephant today.
8. What does the dinosaur eat?
Some dinosaurs ate lizards, turtles, eggs, or early mammals. Some hunted other dinosaurs or scavenged dead animals. Most, however, ate plants (but not grass, which hadn't evolved yet)
7. 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.
6. Are dinosaurs coming 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.
5. How much is a real dinosaur egg worth?
Although the common value exists of a dinosaur egg is about $400 to $1500.
4. Has a preserved dinosaur ever been found?
Scientists have announced the discovery of a perfectly preserved dinosaur embryo that was preparing to hatch from its egg, just like a chicken. The embryo was discovered in Ganzhou in southern China and researchers estimate it is at least 66 million years old.
3. What are the dinosaurs alive today?
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.
2. Did scientists find a dinosaur egg?
Scores of fossilized dinosaur eggs have been discovered over the past century and a half. But eggs containing embryos are rare because the bones of embryonic dinosaurs are so fragile they are often destroyed before the fossilization process is complete.
1. What is the scientific name for a dinosaur?
Dinosaur, (clade Dinosauria), the common name given to a group of reptiles, often very large, that first appeared roughly 245 million years ago (near the beginning of the Middle Triassic Epoch) and thrived worldwide for nearly 180 million years.
