Multiple Phosphatic Nodules from Muncie Creek Shale that I could not Identify ( Missouri )

[Samurai]

Location: Missouri

Time period: Pennsylvanian

Formation: Muncie Creek Shale

 

 

 

Specimen 1: Fish Coprolite? 

1.8cm (nodule size)

 

 

 

 

 

 

Specimen 2: Coprolite? 2cm (nodule size)

 

 

Specimen 3: Fish Mandible? (2.6cm)

 

 

 

Specimen 4: Coprolite or Maybe Braincase (I think it is very unlikely that it is) 

2.8cm Nodule size

1.5cm (fossil size)

 

 

Specimen 5: (2.9cm)

Note: The placement of the fossilized material might be wrong as this was one of my first nodules and the fossilized material fell out. I recovered what I could. (Opened roughly 2 months ago)

 

Specimen 6: Tessellated Cartilage with some Skin impressions ? (2.5cm)

 

Specimine 7: Fish material?
