Scientists may be a tiny step closer to making the Jurassic Park films reality after an exciting new dinosaur find.
They've found what looks like soft tissue in a dinosaur fossil bone, and say the tissue looks like it could be cells and fine blood vessels.
The find means the tissue has survived the bugs and worms that would normally have fed on it 68 million years ago.
The tissue is from the fossil of a Tyrannosaurus rex found in the US state of Montana.

In the Jurassic Park films scientists use something called DNA from dinosaurs found in the blood of mosquitoes trapped in amber for millions of years.
DNA is a special code in every living thing that explains what they are made of.
The scientists behind this find don't know yet if DNA can be extracted from the soft tissue, but the chances of it still existing are thought to be very slim.
Even if the DNA isn't there scientists still hope to learn lots from the tissue about the T. rex and species that may be linked to it and are still alive, like birds.
