Nice photos, Dick, of the patterns on your ammonite shells. They are utterly beautiful.

In the Pennsylvania cyclothem sediments of southeastern Ohio where I grew up, I once found a piece of an ammonite at a coal strip mine. An Ohio University paleontologist identified it for me as a section of one of the giant ammonites that were as much as nine feet in diameter. What a clunky monster that must have been.

I much enjoyed your photos of the Black Pine minerals on this morning's sub stack, which vanished from my desktop. That's a remarkable collection with unusual minerals that you have.

Thanks Steve. Here's the link again if you need it. Black Pine is incredibly complex and interesting! https://www.mindat.org/g/3630

I love ammonites! Thank you for writing this post, I recently saw one at the museum Caracol in TJ MX and it was probably the biggest one id seen.
