Efforts are ramping up to have this region added to the Canadian geopark family. The UNESCO folks just finished their visit. Let's wish them all the success! Possible Nova Scotian United Nations geopark a hidden gem - Keenan

I found a few of these at Joggins fossil cliffs on Nova Scotia. I wonder if it's a nut from the Coal Age tree in the forest fossilized within the cliffs?

Another amateur find. The eyes of the untrained fossil collector can still help Science. Cheers to the astute finder. http://www.cbc.ca/news/canada/new-brunswick/joggins-mount-allison-paleontology-fossils-1.3780594
