Let's start with a list(C. Nasicornis won't be included, as it is the type species)
C. magnicornis
C. dentisulcatus
C. ingens
C. stechowi
C. meriani
Why so many subspecies? because of some anotomical differences...which i see as an invalid reason.
C. Magnificornis is known from one animal that while large, isn't fully grown. That is shown through the many open sutures in the skull. It differs from C. Nasicornis in the fact it has a slightly more rounded nasal horn, which could be a difference between sexes, or an age related trait. other wise, it's pretty similar to C. Nasicornis.
C. Merian appears to be a nomen dubium..
C. Stechowi and C. Ingens are too fragmentary too really know what they truly are..
now that leaves us with C. Dentisulcatus.
It's remarkably stockier then C. Nasicornis, and a tad bit larger. C. Dentisulcatus streches 7-8 meters, with material atrributed to it estimated at 9 meters. Possible sexual dimorphism? Here's a comparison of Dentisulcatus and Nasicornis..
