It has been almost thirty years since the last big fossil skeleton was discovered in Australia.
That makes the three most recent finds even more interesting.
Two of the dinosaurs were herbivores and one a carnivore.
All of them were found in ninty-eight million year old Cretaceous rock.
The remains were found in the outback of Queensland, Australia.
The Carnivore, named Australovenator had three slashing claws on each hand. Compared with Velociraptor because of it's morphology, Australovenator is more closely related to the T-rex relative: Gigantosaurus.
The herbivores are long-necks called Titanosaurs.
One of them Wintonotitan had a more upright neck, similar to a Brachiosaurus.
The other one Diamantinasaurus was a bit more heavily built than Wintonotitan with a slightly shorter neck.
Diamantinasaurus resembled Apatosaurus.
The Carnivore and one of the herbivores were found in an ox-bow lake. These lakes are formed by meandering rivers in which an extremely arced bend of a river becomes cut-off from the rest of the flow, creating a curved lake.
The other skeleton was found in what looks to have been the sandy banks of a gentle flowing river.
Also found with the dinosaurs were imprints of woody stems and branches, cones, ferns and ginkos.
Paleontologists say that they also brought back hundreds of other fossils that they haven't extracted from the rock yet.
Hundreds of fossils are still at the new dig sites waiting to be discovered.
