They're nodular mineral developments. What you're seeing in the cross-sections are mineral crystals--not fossils. All Of The Music And Fossils-Related Pages I've Created

They are not nodular mineral developments. Nodular mineral developments would not contain fossilized fish scales, shark scales, fish vertebrae, crinoids, etc. I know what fish scales, shark scales and fish vertebrae look like. I have yet to see any natural crystal formation anywhere that looks like them. And I posted these on the fossil boards and they also agree these are coprolites.

I also see the twisting in some of the pieces that indicate shark coprolites.

In addition,if you look at the pattern in the 7th microscope photo that clearly looks organic, not a crystal. And the scales I saw in one slice were clearly placoid scales from a shark, which are very distinctive. Thought I photographed it but apparently did not. So I will have to see if I can find that piece again.

rocknrob: There was a shop in Portland, don't know if it's still there called Kenny and Zukes who made the absolute best pastrami sandwiches I have ever had. The problem is every restaurant thinks their sandwich is worth $20 now and seldom makes the grade. Nov 12, 2024 9:53:31 GMT -5

rocknrob: So, to end my thread on sandwiches. If you find your sandwich worthy of that price by all means keep going to that restaurant (chewie)
