Page 4: More Fossil Finds


We found quite a few snails, particularly Sinuites (pictured below).



A few different kinds of coral were found. None were abundant. The most abundant of these was the small solitary horn coral named Streptelasma. It's distinguished from Grewingkia by having attached to objects at it's point. This shows as a flattened edge to the point, rather than the sharp, straight point of the Grewingkia.


On many Richmondian sites, the Grewingkia horn coral are extremely abundant. In this site, however, they were hard to find. Here's one of them...


Just down the road, there was a road cut that gave us lots of the colonial coral, Tetradium. (below)

Don't confuse this with the ubiquitous Bryozoan. Colonial corals are hard to find in the upper Ordovician formations of the Cincinnatian. When in doubt, its' a Bryozoan.. 

Trace Fossils

Every site has some trace fossils. Here's a rock with a bunch of tracks that I think were made by a worm.
