Diamantinasaurus

Reach, Trample
The type species of the genus is D. matildae, first described and named in 2009 by Scott Hocknull and colleagues. Meaning "Diamantina reptile", its name derived from the location of the nearby Diamantina River. The region was an extensive river plain filling the lowlands left behind by the retreating Eromanga Sea. The environment would have been a mosaic of large rivers, freshwater pools, swamps, lakes and coastal estuaries.
