Late this summer I travelled to the site to search for more. After about a half hour of searching and splitting rock, I discovered that the algae and other fossils were concentrated in huge nodules. I collected some tonnage to bring back to "dissect" with a 3 lb sledge and a tile saw. Here's most of what I brought back:
Here's most of what remained as "keepers" after much splitting and cutting:
I was very pleased to have found more algae including what are likely multiple taxa.
