More examples of fossils to come in the spring. I have a bunch of fossils that need worked on with the air abrasive unit, which I don't want to use until it becomes a bit warmer!

Fossils Found in the silica formation
Fossils here include:
Brachiopods,
Corals,
Trilobites,
(The smallest divisions in the ruler are 1/8")
Brachiopods
Mucrospirifer mucronatus (Conrad)
These highly elliptical brachiopods contain numerous lateral ribs.
These are fairly abundant in the Silica Formation.
Formation:
Silica
Age:
Middle Devonian ~370 - 400 m.y
Location:
Silvania, OH
Size:
~ (mm)
This is a plate of Mucrospirifers. Plates of these brachiopods are very
common, however they take an air abrasive unit to properly prep. Each brachiopod is approximately
2" on this plate.
Strophodonta "demissa" (Conrad)
This brachiopod has fine ribbing on each valve.
These are fairly abundant in the Silica Formation.
Formation:
Silica
Age:
Middle Devonian ~370 - 400 m.y
Location:
Silvania, OH
Size:
~ 2" (51mm)
This is a strophodonta in matrix.
No Image Yet, it needs prepped!
Cnidaria Phylum
Corals
The Silica Formation contains a rich variety of corals. The corals easily weather from the
shale, and are therefore easy to collected. The genera in the images below include:
Bethanyphyllum (Stumm), Heliophyllum (Hall), Heterophrentis (Hall),
and possilbly others.
Horn Corals
Formation:
Silica
Age:
Middle Devonian ~370 - 400 m.y
Location:
Silvania, OH
Size:
~ (mm)
Formation:
Silica
Age:
Middle Devonian ~370 - 400 m.y
Location:
Silvania, OH
Size:
~ (mm)
Trilobites
Like all fossils found in the Silica Formation, Trilobites are exquisitely preserved.
The most common trilobites are Phacops rana. However, complete trilobites
are difficult to find. This plate shows how they are more typically found; as bits and pieces.
Preparationn by an air abrasive unit is the easiest way to prep trilos from this formation.
Formation: Silica
Age: Middle Devonian ~370 - 400 m.y
Location: Silvania, OH
Size: The black trilo cephalon (head) is ~1" across (25mm)
(The smallest divisions in the ruler are 1/8")
