It had a *solid* frill, unlike the open frills of the other genera.
[In fact that is effectively the defining character of the genus].
The open frills would be totally useless in actual combat, and indeed
would be extremely susceptible to serious wounds.
Also, it has been claimed (but also denied) that some _T._ specimens
show gouge marks in the frill.

The solid frill is a major difference. One that is largely unexplained.
[Note, I am not saying that more aggressive combat *is* involved in
it origin, I am just suggesting it is a possibility to consider].
The peace of God be with you.
