I'm not going to join but I'll offer logistical support.
First off, you may want to clarify some things:
1.) Are bouts, species segregated? (Like a Karate tournament - Longnecks fight only Longnecks, etc) or is it not species segregated? (Like a mixed martial arts fights - Fast-Runner can fight a Swimmer)
2.) Are there armed combat divisions? (staff and stick fighting and the like?)
3.) Are there specific disciplines that the dinosaurs have to choose? (Like striking only, grappling only, no use of tails, etc.)
