Paralititan is the first dinosaur demonstrated to have inhabited a mangrove habitat. It lived at approximately the same time and place as giant predators Tameryraptor (formerly assigned to Carcharodontosaurus ), [ 13 ] Spinosaurus and the sauropod Aegyptosaurus .
The Morrison Formation records a very diverse dinosaur fauna in addition to fossils of other animals and plants. It is arguably most famous for its plentiful sauropod fauna. In particular, the Howe-Stephens Quarry from which Ardetosaurus is known has yielded associated skeletons of the sauropods Diplodocus and Camarasaurus , the armored ...

An adult would have been about twice as long (15 metres (49 ft) in length) [2] which is still less than half the length of its gigantic kin, like Argentinosaurus and Paralititan. In 2020 Molina-Perez and Larramendi estimated the size of the probable adult specimen (MAD 93-18), which is known from a femur, at 16.5 meters (54 ft) and 10.3 tonnes ...
In the same paper, it is suggested that in a population of Tyrannosaurus adults numbering 20,000, the number of individuals living in an area the size of California could be as high as 3,800 animals, while an area the size of Washington D.C. could support a population of only two adult Tyrannosaurus. The study does not take into account the ...
Aardonyx (Afrikaans aard, "earth" + Greek onux, "nail, claw") is a genus of basal sauropodomorph dinosaur. It is known from the type species Aardonyx celestae found from the Early Jurassic Elliot Formation of South Africa. A. celestae was named after Celeste Yates, who prepared much of the first known fossil material of the species.
