Yep,
A professor named Atari Akari has fine tuned a method to isolate and clone usable DNA from frozen tissue, something that was previously not possible.

Dinosaur Overlord fantasists can pipe down though, as the .au article reports, there are no usable tissue samples to clone a Dino available and even if it was possible, they'd not live long TBH given the drastic change in Oxygen levels and Atmosphere from 65 million years ago ;p
Now all we need is a Woolly Squirrel.....and some nuts ¬_¬
