What is the closest thing to a dinosaur alive today?

In fact, birds are commonly thought to be the only animals around today that are direct descendants of dinosaurs. So next time you visit a farm, remember, all those squawking chickens are actually the closest living relative of the most incredible predator the world has ever known!

How long would at Rex live?

Tyrannosaurus rex had a life expectancy of about 28 years. Previous studies have suggested that it went through a growth spurt in its teenage years, but until recently, scientists didn’t know much about how it grew from a hatchling to a powerful predator.

What was tallest dinosaur?

The Tallest Dinosaur Brachiosaurus – the most well known of the group – was 13 metres tall. Sauroposeidon was massive and probably grew to 18.5 metres tall making it the tallest dinosaur.

What dinosaur has the longest lifespan?

But this technique doesn’t work well on many species, because their bones grew continuously and don’t have neat growth rings. Early estimates of 300-year lifespans for the largest sauropods were based on comparisons with crocodiles and turtles, which have much slower metabolisms.

How did the last dinosaur die?

The last dinosaurs died approximately 65 million years ago. Although the cause of their extinction is still a mystery, climatic change, diseases, changing plant communities, and geologic events could all have played a role.

Did any dinosaurs survive the extinction?

Birds: Birds are the only dinosaurs to survive the mass extinction event 65 million years ago. Frogs & Salamanders: These seemingly delicate amphibians survived the extinction that wiped out larger animals. Lizards: These reptiles, distant relatives of dinosaurs, survived the extinction.

How did mammals survive the extinction of the dinosaurs?

Omnivores, insectivores, and carrion -eaters survived the extinction event, perhaps because of the increased availability of their food sources. No purely herbivorous or carnivorous mammals seem to have survived. Rather, the surviving mammals and birds fed on insects, worms, and snails, which in turn fed on detritus (dead plant and animal matter).

How did dinosaurs get wiped out?

The dinosaurs were wiped out by an asteroid that struck the earth with the force of a billion Hiroshimas, according to leading scientists. The asteroid, the size of the Isle of Wight, slammed into the Yucatan peninsula in Mexico at 20 times the speed of a bullet causing earthquakes, landslides, tsunamis and wildfires.
