CompsognathusMember3 XPNov-02-2013 10:32 AMps i just posted pics so if you refresh your page you will see the pics

Deltadromeus

CompsognathusMember0 XPNov-02-2013 11:09 AMNice, but is say Patagonia is the most dangerous place, and Africa is the second.

Rex Fan 684

CompsognathusMember0 XPNov-02-2013 11:36 AMDecent list. All 5 were very dangerous places. I think your sizes are a bit off(Sinotyrannus for example was at most 10 meters, not 11), but that does not have a whole lot to do with the list itself.

Tyrannosaurus RexMember6270 XPNov-02-2013 1:58 PMGood list. I agree with it.

Nice, although here's my ranking:

5) China

Home to some primitive Tyrannosaurs.

4) Mongolia

Home to two of the largest Tyrannosaurs, Tarbosaurus and Zhuchengtyrannus, plus the infamous Velociraptor.

3) Patagonia

A land of giants, ruled by Giganotosaurus and Argentinosaurus.

I'd put North America and Egypt as equals, given how the latter was a land of carnivores whilst the former was the domain of the deadliest terrestrial carnivore of all time.

Don't know which dinosaur I'm referring to?

Tyrannosaurus Rex, the tyrant king.  DUH.
