Prehistoric Death Battles: Riveting Rivalries

I'm still in the process of finishing up Prehistoric Death Battles: Carnivorous Carnage. For those of you that don't know, it follows a tournament format, and I've written the first two fights. However, I don't have enough time to finish Round 1, so I thought I'd announce the next season of PDB, which is Riveting Rivalries. Basically, the series shows fights between dinosaur rivals, and I'm including two fights from PDBS2 in this season, and you can expect a lot of Tyrannosaur vs Ceratopsid or carnivore vs sauropod fights. Here are the rivalries, and the first two have their links:

1. Tyrannosaurus rex vs Triceratops

2. Utahraptor vs Gastonia

3. Tyrannosaurus rex vs Eotriceratops

4. Tyrannosaurus rex vs Alamosaurus

5. Spinosaurus vs Sarcosuchus

6. Carcharodontosaurus vs Paralititan

7. Dakotaraptor vs Pachycephalosaurus

8. Albertosaurus vs Styracosaurus

9. Tyrannosaurus rex vs Ankylosaurus

10. Stegosaurus vs Allosaurus

11. Torvosaurus vs Allosaurus

12. Daspletosaurus vs Chasmosaurus

13. Giganotosaurus vs Mapusaurus

14. Giganotosaurus vs Argentinosaurus

15. Allosaurus vs Diplodocus
