So, from the same road-cut, same layer as the object I just posted. Figure 1 is the "dorsal" surface, Figure 2 is the narrowed end through matrix. This one is better preserved to the point I can see circumferential "channels" in the margin (white arrows) and two lateral edges or "alae"? (A and B ) (Figure 3). Question-do you think it would be of any benefit to lift off the layer depicted? (Blue arrow in Figure 4). How would/could I even clean away all the other matrix? What are the "channels"?, So many questions!!....Cool eh? Thanks again and my apologies for hogging the forum! Bone
