Woolly Mammoth  (Source: blog.devonanddorsetcottages.co.uk)
A researcher from Japan plans to use a new cloning technique to make this happen

If you thought "Jurassic Park" and the large, reconstructed skeletons seen in museums were the closest we'd ever come to seeing extinct creatures come to life, you might want to think again.  

Akira Iritani, a professor at Kyoto University in Japan, is looking to resurrect the woolly mammoth now that a new cloning technique can make it possible. Not only is it possible, but the woolly mammoth could also be reborn as soon as four years from now.  

The woolly mammoth, which is an extinct species of mammoth that died out 5,000 years ago, has been difficult to clone up until now because nuclei in cells found in the muscle tissue and skin of woolly mammoth's located in the Siberian permafrost were severely damaged by the cold. Many attempts in the 1990's failed because of this. 

In 2008, Dr. Teruhiko Wakayama from the Riken Centre for Developmental Biology developed a cloning technique that allowed him to use the cells of a mouse that was frozen for 16 years to clone a new mouse. This technique has paved the way for new clone-related opportunities, and has inspired Iritani to resurrect the woolly mammoth.  

Iritani plans to use this technique to pinpoint healthy nuclei within mammoth cells in order to extract and use them for cloning.  

"Now that the technical problems have been overcome, all we need is a good sample of soft tissue from a frozen mammoth," said Iritani. 

To obtain the nuclei, Iritani will travel to Siberia this summer to find samples of mammoth tissue or skin within the permafrost. If he is unable to locate these samples, he plans to ask Russian scientists for samples that they have recovered. 

Once Iritani obtains the nuclei, he will insert it into an African elephant's egg cells. The African elephant will be the surrogate mother of the new mammoth. 

"The success rate in the cloning of cattle was poor until recently, but now stands at about 30 percent," said Iritani. "I think we have a reasonable chance of success and a healthy mammoth could be born in four or five years."

Iritani said the process would take at least four years because it will be about two years before the elephant can be impregnated, and then a 600-day gestation period is needed.

"T. Rex Soft Tissue Found Preserved"

I'm pretty sure the DNA was lost/damaged beyond any hope of cloning, but who know's what else is waiting to be found, improbably preserved...

Ah, yes, here we go. The first story was 2005. But, later, in 2010:

We might be able to control land creatures, but don't clone the sea-dwelling or the flying dinosaurs.

When they do get the T-Rex-periment going, I'm going to get an RPG

Don't worry, they wouldn't survive. The atmosphere was very different back in the days of the dinosaurs. the air pressure was almost twice what it is today, CO2 levels were much, much higher, and O2 levels were higher. Dinosaurs couldn't survive our atmosphere.

FWIW, I am no fundy, but that link summarizes the findings of that T-Rex "tissue" sample. Here is another one that goes into some detail on what they found:

There were a lot of assumptions on this one. IIRC, there was even a Discovery documentary on it.

That is why they use frog DNA to fill-in the gaps.

You might as well use plant DNA and probably will get the same results. Nothing. Because the strands are so degraded beyond repair that you won't get anything close to the real thing.

There is another problem with cloning a real dino...

The oxygen levels on earth is different than what it was 30~100 million years ago. There was much more oxygen, which allowed for bigger animals.

That is debatable. Lots of large creatures around now that still lived long ago.

The main reason, according to who you ask, is simply was more food around then combined with the heat. Heat burns energy faster, making for hungry animals.

No... we DO want to clone dinos...

For the meat! Imagine that... T.Rex steak!

You successfully craft 1 Dragon Steak.

The good about dragon steak is that (if you ask politely) the dragon can cook itself...Swooosh! Ding! It's ready come to eat me!

It's all gonna taste like chicken but more of it. On second thought, what a splendid idea!

That was my initial impression but perhaps not since T-Rex is a meat eater.

T-Rex was a scavanger. Just get small sized ones and feed all the road kill to them.
