“They would smash all the way through the bones and crush them. You would be dead from the shock very quickly. Your experience wouldn’t be over.

Who did dinosaurs eat?
Dinosaurs ate lizards, turtles, eggs, or early mammals. Some people hunted other dinosaurs. Most ate plants, but not grass, which hadn’t evolved yet. Dinosaurs ate a wide variety of plants, including grasses, trees, shrubs, and vines.
They also ate other animals:
- Such as small mammals
- Birds
- Reptiles
- Amphibians
- Fish
- Insects
- Mollusks
- Crustaceans
- Snails
- Slugs
- Worms
- Spiders
- Centipedes
- Arachnids
- Nematodes
- Protozoa
- Bacteria
- Viruses
- Fungi
- Algae
- Cyanobacteria
- Lichens
- Sponges
- Other invertebrates
In addition, some dinosaurs were herbivores, eating plant matter, while others were omnivorous, consuming both plant and animal matter. The dinosaurs that ate the most plants were the ones that lived in warm climates, like the Triassic period, the Jurassic period and the Cretaceous period.
Who was the scariest dinosaur?
The t-rex, utahraptor, and jeholopterus are some of the scariest dinosaurs we’ve seen, but the heterodontosaur may be the scariest of all. It was a small fanged dinosaur species that lived around the toes of North America during the late Cretaceous period.
The new species is named for the fossilized remains of the creature, which was about the size of a house cat and lived in what is now the United States, Canada, Mexico, and parts of Central and South America, according to a study published in the Journal of Vertebrate Paleontology.
The fossil was found in a limestone quarry near the town of El Paso, Texas, by paleontologists from the University of Texas at Austin and the National Museum of Natural History in Washington, D.C. “This is the first time we’ve ever found a dinosaur that’s so small,” study co-author Mark Norell, an associate professor of geology and geophysics at UT Austin, told Live Science in an email.
Can dinosaurs survive today?
Variables such as temperature, food sources, and oxygen levels can affect dinosaur survival. Dinosaurs lived in warmer climates millions of years ago, so experts don’t think they could have survived in the northern part of the planet.
Arctic is a very different environment than the rest of the world,” said study co-author David Evans, a paleontologist at the Natural History Museum of Los Angeles County in California.
What killed the dinosaurs?
Scientists already know that an asteroid—or perhaps a comet—struck Earth off Mexico’s Yucatán Peninsula. The crater is thought to have caused a decades-long impact winter on the planet. Slide me › The impact of a large asteroid or comet on Earth is known as an impact winter.
A meteorite is a piece of rock that has fallen from the sky and hit the ground. Meteorites can come in a variety of sizes, shapes, and colors, but they all have one thing in common: they are made of the same material as the meteorites that fell to Earth millions of years ago.
Would at Rex eat a person?
T. rex would be able to eat people. The bite marks on the bones of triceratops and edmontosaurus were similar to those of t. rex. “It’s just a matter of how big they were and how much food they could eat.” Dinosaurs are known to have eaten a wide variety of prey, including small mammals, birds, fish, reptiles, amphibians and even humans.
In fact, some of the largest animals ever to walk the Earth — including Tyrannosaurus Rex, the world’s largest carnivorous dinosaur — were herbivores, eating plants and other plant-based foods. (Tyrannosaurus was a carnivore, too, but it was more of a scavenger than a predator.
Did humans and dinosaurs live at the same time?
After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. Small mammals, including shrew-sized primates, were alive at the time of the extinction event. Scientists have long debated whether or not these mammals were wiped out by the asteroid impact, or whether they survived and evolved into modern-day mammals.
Now, a new study published in the Journal of Vertebrate Paleontology suggests that the latter may have been the case.
The study, led by a team of researchers from the University of California, Santa Cruz, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, found that mammals that lived during the Cretaceous-Paleogene (K-Pg) extinction were more closely related to modern mammals than they were to the ancestors of modern humans.
In other words, they may not have evolved from a common ancestor, but were instead the result of a merger between two different lineages of mammals, the researchers said. The researchers analyzed the genomes of more than 1,000 mammal species from around the world and compared them to a database of human genomes.
How did dinosaurs come to Earth?
Dinosaurs arose from small dinosauromorph ancestors in the Triassic period, when the climate was harsh and dry. They faced competition from the croc-line archosaurs for tens of millions of years, but finally prevailed when Pangaea began to split, according to the study.
The study, published in Nature Communications, is the first to look at the fossil record of dinosaurs in detail. The researchers used a technique called high-resolution X-ray fluorescence (HRIX) to analyze the chemical composition of the dinosaur bones.
