paleonet Comanchean/Gulfian Unconformity

[Dee Ann Cooper <deeanncooper@xxxxxxxxx>]

does anyone have any information on the duration of
this unconformity in West Texas?  We are trying to
determine if the Cenomanian/Turonian Stage Boundary
occurs within the Boquillas Formation or during the
unconformity between the Buda Formation and the
Boquillas Formation ... we do have one Collignoniceras
woollgari (middle Turonian?) within 5 stratigraphic
feet of the base of the Boquillas Formation, however,
most published information suggests that the
Cenomanian/Turonian Stage Boundary is well above the
base of the Boquillas.  Cheers,
