All the heavy rains have provided great collecting at the road cuts outside the city. The Ordovician fossils that are the most common is the brachiopod. This brachiopod is a Platystrophia of some type. What I found interesting was this Cornulites that anchored itself in the groove of the brachiopod shell. It is thought to be a tubicolous annelid worm that orientated itself for feeding. Since this one was pointing toward the shell opening, it probably attached and grew there while the brachiopod was still alive.

The encrusting critter is a Cornulites. An enigmatic fossil of unknown origin, but probably related to molluscs.
Those are Cornulites. An enigmatic fossil of unknown affinity, but probably related to worms, or mollusks.
