Comments:
The Tricrepicephalus species in the Weeks Formation referred to as Tricrepicephalus coria, have been synonomized with Tricrepicephalus. texanus (see Pratt, 1992, Peters, 2003), although this is not as yet universally accepted. The jury is still out until more specimens of Tricrepicephalus are found.
