I can't add to that, but I can say that grasses _were_ around at that time
period. There is this roadcut in ND where I find leaves, and once upon a
time thought I was also finding "twigs." Upon more thoughtful examination,
these "twigs" were grassblades, very similar to those which were alive and
growing among the nodules I was looking at there in the Bullion Creek
formation, south central ND.

Both fossil and modern grass sit amongst each other in my collection
