Ankylosaurus died out 65.5 million years ago, at the same time as all non-avian dinosaurs, pterosaurs, plesiosaurs, and mosasaurs went extinct. They died out during the K-T Extinction Event, which is believed to have been caused by a 6 mile wide asteroid that crashed into the Yucatan Peninsula, leaving a 100 mile wide crater. The dust and ash thrown into the atmosphere blocked sunlight for months or years, which killed plants, as well as the animals that ate them, including Ankylosaurus.
Like other animals, Barosaurus were vulnerable to many types of deaths. Juvenile and hatchling Barosaurus would have often been killed by predators, and even adults may have been hunted. They could also die from disease or accidents. If you meant to ask, "How did Barosaurus become extinct?" nobody knows for sure. They lived about 150 million years ago, and died out long before the asteroid impact that famously eliminated all existing, non-avian dinosaur species 65.5 million years ago.
They either were destroyed along with the other dinosaurs or they slowly died out because of change of diet of lack of children.
Baryonyx lived between 130-125 million years ago.
It could but only Dinosaurs like routops and oranasaurus
· Bactrosaurus · Barosaurus · Brachiosaurus · Brachylophosaurus
if temperature drops quick enough, plants die. if plants die, the dinosaurs that eat plants die. if those dinosaurs die, then the carnivorous meat-eating dinosaurs die. then, all dinosaurs die.
Barosaurus is actually the genus, while lentus is the species. So, the full scientific name is: Barosaurus lentus
Birds are direct descendants of dinosaurs so they did not die out.
Dinosaurs Don't Die was created in 1975.
i think they live in the gongle
10 inches
Yes
they saw you
They already did. All the dinosaurs died out 65 million years ago.
The sheer bulk of Barosaurus kept it safe from predators, so a full grown adult would be fine. Young, old, sick, and weak would probably be hunted by Allosaurus, though.
