Ceraurus milleri and Meadowntownells sp., Ordovician (Kirkfieldian), Hastings County, Ontario, Canada -
Images have the sharpness and definition turned up to hopefully see more detail. I wish I could say the formation but the map I was looking at was particularly large and I just couldn't really tell. All I can say is that all of the possible formations were from the ordovician period. The first rock is 2.54 centimeters wide, and the second is 19.05 centimeters wide. I was thinking that it was a coral maybe? The shape reminds me of brain coral, but I also haven't seen any coral fossils like this one so I don't know. Sorry if the photos are bad, I took them on

Ceraurus mantrenseris, Upper Ordovician, Ottawa, Ontario, Canada -
Only for who is familiar with decalcified material. Upper ordovician, Italy. Scale bar 5mm. Decalcified specimen are preserved as the internal and the external mould, so the calcified part occupied the space between the two moulds. On the left side: the two moulds of the first specimen On the right side: only one mould available of another specimen (I guess conspecific), worst preservation. Any idea of what could be?
