What would have happened if a duo of Polacanthus met with the largest Abelisaurid ever named, Pycnonemosaurus, battled with each other? Would the Polacanthus duo use teamwork to their advantage and defeat the Pycnonemosaurus, or, would the teamwork Polacanthus duo not be enough and lose to the Pycnonemosaurus? Let's find out as we check out Mesozoic world battle series.

Note: some (yes some, because some of them might not be from the Dinopedia pages) of the info I'm getting is from the Dinopedia pages of both dinosaurs.

In the red corner, we have the largest Abelisaurid named, Pycnonemosaurus.

Pycnonemosaurus stats:

Size: 8.9 meters in length and 4 metric tons in weight

Speed: 27 mph

Bite force strength: most likely high

Weapons: large size, powerful bite, and speed (bias to speed not intended)

Defence: some osteoderms

And in the blue corner, we have a Polacanthus duo

Polacanthus duo stats:

Size: 5 meters and 2 tons (10 meters and 4 tons when added up)

Speed: N/A but I do know it is slow (I couldn't even find anything useful)

Bite force strength: N/A

Weapons: spikes, tail spikes, numbers, armor

Defence: armor, sacral shield, spikes

Pycnonemosaurus advantages: bite strength, larger (when not adding them up), and faster

Polacanthus duo advantages: better defence, tail spikes, sacral shield, numbers, armor, lower center of gravity

Pycnonemosaurus disadvantages: higher center of gravity, alone, little armor, less better defence, no sacral shield, no tail spikes

Polacanthus duo disadvantages: slower speed, no bite strength, and smaller

Where it will be taking place in: an amethyst cave

Plot:

A Polacanthus duo is seen with each other walking in a cave and would later on stumble upon an amethyst cave, a cave that they do not recognize. A Pycnonemosaurus would later stumble upon the Polacanthus duo and the amethyst cave. The Pycnonemosaurus would let out a roar-like sound before charging at the Polacanthus duo. One of the Polacanthus would rear up and would try to slam the Pycnonemosaurus on the leg only for the Pycnonemosaurus to walk over the Polacanthus' tail and would try to bite the other Polacanthus on the neck only for the Polacanthus to rear up and slam its spikes onto the Pycnonemosaurus on the back of the ankle pushing it forward. The Pycnonemosaurus would roar at the Polacanthus duo and would bite one of them on the tail and would lift it slightly off the floor and would slam it on the amethyst knocking it out the Polacanthus. The other Polacanthus would charge at the Pycnonemosaurus and would slash the Pycnonemosaurus on the foot after it tried to stomp it on the back and would later on try to slash it on the leg only for the Pycnonemosaurus to bite the Polacanthus on the leg and would pick up slightly off the floor and would throw it a few meters away. The Polacanthus that was knocked out by the Pycnonemosaurus would get up but would later bellow at the Pycnonemosaurus and would charge at it and would rear up and would try to stab it on the chest with its spikes only for the Pycnonemosaurus to bite it on the neck and would lift up slightly off the floor but the Polacanthus would slash it multiple times on the side and after that, the Pycnonemosaurus would throw it and after that, the Polacanthus would be stabbed on the chest by a sharp piece of amethyst causing the Polacanthus to bellow in pain before letting out a final bellow before closing its eyes lifelessly, dead. The Polacanthus that didn't die would see the Pycnonemosaurus looking at his friend and the Polacanthus would let out a bellow, angered at the death of his friend. The Polacanthus would later on slam the Pycnonemosaurus on the leg with his tail before stabbing the Pycnonemosaurus on the chest, injuring the Pycnonemosaurus. The Pycnonemosaurus would later look at the Polacanthus before walking away injured by the deadly blow. The Polacanthus would later mourn and would bellow in victory.

Conclusion: Though the Pycnonemosaurus was able to dispatch one of the Polacanthus in the duo, it was too distracted on his kill before being injured heavily by the last Polacanthus of the group and would be defeated. Pycnonemosaurus may have been larger but the Polacanthus spikes and armor were just a bit much for the Pycnonemo to handle.

Winner: Polacanthus
