Refined age and geological context of two of Australia’s most important Jurassic vertebrate taxa (Rhoetosaurus brownei and Siderops kehli), Queensland

Of these, the spectacular and extremely well-preserved giant amphibian, Siderops kehli, and the only known pre-Cretaceous sauropod in Australia, Rhoetosaurus brownei, are perhaps the most important.
