Placoderm Thoracic Plate?


Late Start Fossil Girl

Recommended Posts

My first question as a new member to the forum. Are these two placoderm plates?

The serrated edge caught my attention, as well as the hard, bone like feel and color to the fossil. 

They are very different from the brachiopods, coral, or other Devonian fossils I have found.

This came from the Deer Lake area north of Cabelas as was suggested by another fossil forum member.

Welcome to the Forum. :) 

This is a very interesting piece.

Welcome to the forum.

 

The "studding" is very similar to certain bivalve species with raised pallial lines/muscle scars. It also has the appearance of an internal mold to me.

Thank you. I’m going to read up on all the suggestions you made.

Left edge of fossil has been broken off so it should be longer then the 4.5 mm shown.

I had the same thought.

 

Also, I think the specimen is 4.5 cm not 4.5 mm.
