What were the Velociraptors?

 


Joel Kontinen

Velociraptors were turkey sized animals. The dino sized things in the film Jurassic Park described what these Cretaceous predators looked like Deinonychus. That was what scientists thought at that time.

”In 2007, researchers confirmed that Velociraptors had feathers. The presence of feathers gave Velociraptors a whole new look that was far more bird-like than how they — or Deinonychus — were previously depicted.”

that is what evolution says.

Dinosaurs may have run like emus by keeping one foot on the ground

How did dinosaurs run? According a new  study, they run like emus, which is strange.

“If you want to imagine a dinosaur running, then perhaps look at emus. They probably shared a similar posture, which makes it most energy efficient to keep one foot on the ground when running at an intermediate pace.

Pasha van Bijlert at Utrecht University in the Netherlands and his colleagues wanted to understand why birds have a style of running that is so different to humans.

For instance, emus (Dromaius novaehollandiae), which can sprint at up to 50 kilometres per hour, always have one foot on the ground when running at intermediate speeds. This was thought to require much more energy than the “aerial” running style, in which both feet are off the ground at the same time, which is seen in other bipeds, such as people.

To learn more, the scientists built a computer model based on an emu and used physics simulations to measure the energy output of different running styles, while varying the bird’s anatomy.

“These are all changes you can’t really make in a real bird, but they represent differences between different bird species,” says van Bijlert. “For example, quails are very crouched and their tendons probably don’t store a lot of energy. Emus are, comparatively, pretty upright, but their tendons store a lot of energy.”

But dinosaurs and emus have lots of differences, Emus are birds, and dinos are not. God created each species in its own way and dinos can never really run like emus.

Britain’s ‘dinosaur highway’ discovered as hundreds of footprints found in quarry

A newly discovered ‘dinosaur highway’ has been discovered buried under mud in a quarry in England.

Researchers have discovered nearly 200 dinosaur footprints dating back 166 million years, changing what we knew about the creatures.

The dig, carried out at Dewars Farm Quarry in Oxfordshire by teams from the Universities of Oxford and Birmingham, uncovered five extensive trackways, forming part of a ‘dinosaur highway’ – with evidence of more in the surrounding area.”  

In this research, the millions of years have teemed up with evolution,  as if these dinosaurs truly lived at that time, but many things say that they did not live at that time as dinosaur DNA does not last that long. .
