Spinosaurus vs. T. rex ( Ultimate match for the biggest and baddest dinosaur )

Spinosaurus

Spinosaurus is a carnivorous dinosaur which lived in some parts of North Africa & South Asia. It roamed on Earth about 95-75 years ago in Cretaceous period. Spinosaurus is known to be the biggest carnivorous creature ever to roam on this Earth. Measuring about 7 to 9 tonnes in weight and with a length of about 16 - 18 meters, this large lizard had sail like structure on its top.

Tyrannosaurus Rex

Tyrannosaurus rex is a well known carnivorous dinosaur which lived in some parts of North America . T-Rex lived in the last part of Cretaceous period. Most fossils discovered are dating back to 68 - 65 million years ago. Estimates suggest that it had a length of about 12 meters & a height of about 4.5 - 6 meteres. It had a weight of about 7 tonnes.

That was a little look at our two candidates.

Let's have another brief look at some features of these two giants.

PS- Spino & T-Rex lived in different periods. So, there is no way that Spino had a battle with T-Rex unless if there was time traveling in those days ;). hehe!! anyways, i thought of writing this to compare both of these awesome creatures with each other.
