Point Riche, Port aux Choix, Newfoundland


The coastline of Point Riche exposed thickly bedded limestone, with numerous fossils preserved. The fossils in the rocks were very bioturbated, indicating that they were deposited in a rough environment, probable close to shore.

The fossils that we found in the area were mainly cephalopods and gastropods. Some of the cephalopods had been recrystallized with calcium carbonate.
There was also deposits of chert (quartz) that was brownish blackish and distributed in random patterns. This chert is probable a form of secondary percipitation. It could have been that the chert filled in burrows left by animals and as the water flowed through the borrows eventually the chert was percipitated.
