Are sharks dinosaurs?
Today’s sharks are descended from relatives that swam alongside dinosaurs in prehistoric times.
In fact, the largest predator of all time was a shark called a Megalodon.
It lived just after the dinosaurs, 23 million years ago, and only went extinct 2.6 million years ago..
What was a dinosaurs lifespan?
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.
How old is the Megalodon?
The earliest megalodon fossils (Otodus megalodon, previously known as Carcharodon or Carcharocles megalodon) date to 20 million years ago. For the next 13 million years the enormous shark dominated the oceans until becoming extinct just 3.6 million years ago.
Are chickens descendants of Velociraptors?
Bev 272. I was watching a TV show the other day and Jack Horner, paleontologist from the Museum of the Rockies in Montana said that chickens were the direct descendants of Velociraptors – I’m probably spelling that wrong. … Chickens are NOT classed as raptors in the bird world.
What dinosaur did the chicken evolve from?
VelociraptorAs dinosaurs morphed into birds, they shrank dramatically and adopted a more babylike skull shape. Shown left to right: Velociraptor, a dinosaur of the class that gave rise to birds; Archaeopteryx, often called the first bird; and a modern chicken and pigeon.
What is the closest thing to a human?
chimpanzeesEver since researchers sequenced the chimp genome in 2005, they have known that humans share about 99% of our DNA with chimpanzees, making them our closest living relatives.
Which is older dinosaurs or sharks?
As a group, sharks have been around for at least 420 million years, meaning they have survived four of the “big five” mass extinctions. That makes them older than humanity, older than Mount Everest, older than dinosaurs, older even than trees.
What came first dinosaur or man?
Non-bird dinosaurs lived between about 245 and 66 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous.
What did T Rex really sound like?
Scientists aren’t sure what T. rex sounded like, but the best guesses are based on the dinosaur’s closest living relatives: crocodiles and birds. A 2016 study suggested that T. rex probably didn’t roar, but most likely cooed, hooted, and made deep-throated booming sounds like the modern-day emu.
Are chickens smart?
4 They’re super smart. A recent study has shown that chickens are intelligent and emotional animals, and are able to “demonstrate thinking skills on par with mammals and primates”. If you hide an object from a chicken, they will still know it’s there — this is something even young human kids aren’t able to do.
What is the closest thing to a dinosaur?
crocodilesDinosaurs are classified as reptiles, a group that includes crocodiles, lizards, turtles, and snakes. Of this large group of animals, other than birds, crocodiles are the closest living things to dinosaurs.
What animal is closest to T rex?
chickenWith scientists having named the chicken as the closest living relative of the mighty T-Rex, a second group of researchers have decided to put the findings into practice – by strapping a fake dinosaur tail to the birds.
Did a chicken come from at Rex?
Tyrannosaurus rex, meet the chicken – your third cousin more than 100 million years removed. A new family tree based on protein sequences recovered from dinosaur fossils firms up the dinosaur’s avian lineage. “Palaeontologists have known this overall connection.
Are any dinosaurs alive today?
In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.
What dinosaurs had 500 teeth?
NigersaurusNigersaurus had a delicate skull and an extremely wide mouth lined with teeth especially adapted for browsing plants close to the ground. This bizarre, long-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with more than 500 replaceable teeth.
Did dinosaurs evolve into chickens?
The idea that birds evolved from dinosaurs has been around since the 19th century, when scientists discovered the fossil of an early bird called Archaeopteryx. … By doing so, they have managed to create a chicken embryo with a dinosaur-like snout and palate, similar to that of small feathered dinosaurs like Velociraptor.
Can dinosaurs come back?
While dinosaur bones can survive for millions of years, dinosaur DNA almost certainly does not. But some scientists continue to search for it – just in case. So it looks like cloning a dinosaur is off the table, but an alternate way to recreate the extinct animals would be to reverse-engineer one.
What killed the Megalodon?
A new study suggests that a tsunami of cosmic energy from a supernova killed off large ocean animals – including the huge megalodon shark – 2.6 million years ago. A shower of particles may have spelled curtains for the megalodon, a school-bus-sized shark, 2.6 million years ago.
