With pretty crystal growth. From NE Wyoming. I'm guessing calcite and barite replacement and crystals but not really sure. The third pale gray one looks like it's agatized / chalcedony replacement but I haven't acid tested it. The air chamber on that one is hollow which is uncommon and makes it very translucent. |

I agree with Pat. Not boring at all. I think they're beautiful!  |

Fine specimens tims. Those connecting joints are so mechanically sophisticated, true mind blower. Mine glow orange in short wave. Must be the barite but not sure. |

Yes, the suture lines always make me wonder how these critters functioned mechanically and how limber they might have been in life (I'm guessing not very). Sometimes I'll find long pieces with half a dozen or more individual segments cemented together and they're always straight as an arrow, so I'm not sure if they're designed for articulation or something else entirely. |

Much of the blue crab's belly structure is a sophisticated connection structure that has little pivoting movement but in no way as complex as a baculite joint.  |

Cool baculites. Love them. I find a few where I live and have only found one that I think is agatized. Love the suture patterns and when polished they look amazing. Not sure what to do with the agatized one yet as I am too scared to wreck it. May try polishing it in the future.
