Cooper and George the Huge Australian Titanosaurs

Cooper and George Titanosaurs

Cooper and George are the names given to two huge Titanosaurs that were found in Queensland Australia.  Cooper, the smaller of the two Sauropods, is known by a 5 foot or 1.5 meter long humerus.  That is the upper arm bone.    The bigger of the two, George, is know due to a 6 foot or 1.8 Gmeter long femur.  This is the upper leg bone.  George is estimated to have been around 82 feet or 25 meters long.  On the other hand, Cooper was possibly the bigger of the two.  

Some Paleontologists think that Cooper may be more closely related to Apatasaurus.  There are even estimates that the biggest of the two could have been 100 feet or   meters long.  In any case, these are the two biggest dinosaurs ever found in Australia.  

Since Australia was once part of the Supercontinent called Gondwanna. . . that included South America, it makes sense that they would be Titanosaurs, or at least closely related to Titanosaurs....since Titanosaurs lived in South America.  

Now, if I have confused you I apologize.  The research on these two monsters is being done now.  There may be more and different conclusions or inferences as the studies continue.  Also, is is certainly possible that more fossilized bones will be found and shed more light on the size issue. 

Neither animal has been officially named, as far as I know.  Maybe the Cooper and George fossils will turn out to be from the same species of Sauropod.  In my drawing they are different species. . . . unless it turns out that they are not different species . . . then what you see in my drawing is sexual dimorphism.  The male looks somewhat different from the female.
