How about Patuxentites since these are ichnites from the Patuxent Fm. of the 
Potomac Grp? Stratigraphically and possibly  temporally, it would help to use 
names indicative of the _formational_ unit and/or the textural differnces 
between the overlying Arundel Clay (predominant clay/silt)and the predominant 
sands, gravels, and iron cemented mudstones and ss of the Patuxent Fm. We 
could also come up with something based on the inferred paleoenvironment as 
well. 

Ray,

I have just about gotten my system back on line and hope to catch up on email 
over the weekend. If you want some suggestions based on the above criteria 
let me know.
