Americaspis americana, dorsal shield endocast from jawless fish, Silurian in Pennsylvania
traveltip1 posted a topic in Fossil Hunting Trips
I found these, endocast impressions of dorsal shields of the jawless fish Americaspis americana, in the Silurian of Pennsylvania. There are 2 1/3 dorsal shields shown. A complete shield measures approximately 2.4 x 1.0 inches (6.10 x 2.54 cm).

From the album: Chondrichthyan Teeth From The Pennsylvanian Period
The more flattened version and 3 extra fragments from another Petalodus -
Hello and good evening! I have passed this fossil a few times and it resides in a large limestone slab. I believe it could be a spine due to presence of Chondrichthyan teeth in the area and how it appears to come to a point. For reference the teeth I have found include teeth from Petalodontiformes, Eugenodontida, and other Chondrichthyans. I will note I have found some petrified wood in the area, but none in a limestone matrix so it could be a Calamite. Location: Missouri Time period: Pennsylvanian Formation: Muncie creek shale member

Multiple Phosphatic Nodules from Muncie Creek Shale that I could not Identify ( Missouri )
Samurai posted a topic in Fossil ID
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? Thank you for reading and viewing this, I hope I can better understand these images so I can use them as references in the future!

I believe this to be apart of a Petalodont root as I found the tooth in the previous image right next to this one -

I believe this to be a Caseodus tooth but if this is the wrong, possible id's are welcomed! -

I assume this is some sort of bone either from a fish or some sort of other specimen. It could be a spine of some sort but I am extremely doubtful -

Hi all, had these in the collection for a bit but need help with ID's. These come from Big Brook and guessing they are assorted fish bones and possible turtle bones.

More Information On Enchodus marchesettii? papers, ect.
Mioplosus_Lover24 posted a topic in Questions & Answers
In my collection I have an Enchodus marchesettii, but in doing more research I am unsure about the relationship it has to other Enchodus, and it's spread as there seem to be very very few specimens, and most are mislabeled Eurypholis or Spaniodon. I am just very interested if anyone has any papers on Lebanon fish. -
Members, during a trip to Brazil almost 20 years ago, I purchased this composit of 4 different fossilized fish. The fossils of the fish look authentic and I tried to take photos to demonstate the relief of each fish. But I beleive they were "arranged" into this one piece. Not sure if and how getting 4 fossils into one piece is done. I am more interested in knowing if the fish are indeed authentic and what the individual species of each are? Also, is it possible to gague what period they are from? I am hoping someone will tell me that I did not haul this 10 lb piece back to the US in vain. Thanks in advance. I look forward to any response and hope everyone is safe and well. Respectfully, Dubs

Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale Found this very small tooth like structure and was wondering if anyone could confirm if it is a tooth or not. Normally I can identify teeth if they are large enough, but this specimen is very small. I have found teeth before in these concretions but much larger such as a possible Symmorium or Glikmanius along with a tooth from a member of Eugeneodontida. Here are some images I edited that might make some details more clearer:
