Is a T rex bigger than a Spinosaurus?

More videos on YouTube The water-loving Spinosaurus had a spiny “sail” on its back, and a crocodile-like head, neck and tail, but was much larger than the Tyrannosaurus Rex. At 50 feet long, it's the largest carnivore to walk (and swim) the Earth… that we know of.

Why does at Rex have small arms?

rex's puny, undersized arms. According to Steven Stanley, a paleontologist at the University of Hawaii at Manoa, T. rex arms were used to slash prey in close proximity to the dinosaur. ... And the short arm length was actually more beneficial for slashing, considering the size of T.

Why do carnotaurus have small arms?

As fearsome as Carnotaurus looked, though, it's hard not chuckle at the dinosaur's arms—the hand and lower part of the forelimb were so reduced in size that some paleontologists have viewed them as vestigial structures that have almost entirely lost their ability to function in acquiring prey.

Why did carnivorous dinosaurs have small arms?

The precise purpose of T. rex's relatively tiny arms has long been mysterious. Over the years, scientists have suggested that they might have been used to grasp struggling prey, to help resting dinosaurs push themselves up from the ground, or to grip tight to mates during sex.

Is cloning a dinosaur possible?

"We are a long, long way from being able to reconstruct the DNA of extinct creatures, and in fact it may be impossible to resurrect the DNA of dinosaurs or other long-extinct forms. We have DNA for living creatures, including ourselves, and yet we cannot clone any living animal (from DNA alone).

Can we clone Neanderthal?

Which means that it's virtually impossible to clone in the only way that we know how to do - with the transfer of DNA from one individual into an egg cell. That means the only way to do it is synthetically, as Church suggests. However, the Neanderthal sequence is still not 100% complete.

Can humans clone?

There currently is no solid scientific evidence that anyone has cloned human embryos. In 1998, scientists in South Korea claimed to have successfully cloned a human embryo, but said the experiment was interrupted very early when the clone was just a group of four cells.

Were Neanderthals more intelligent?

“They were believed to be scavengers who made primitive tools and were incapable of language or symbolic thought.”Now, he says, researchers believe that Neanderthalswere highly intelligent, able to adapt to a wide variety of ecologicalzones, and capable of developing highly functional tools to help them do so.

Can we clone a mammoth?

Cloning, as geneticist Beth Shapiro points out in her book How to Clone a Mammoth, requires an intact and viable mammoth cell. No one has found such a cell before, and, given how cells degrade after death, it's unlikely that a suitable cell for cloning will ever be found.
