4 years, 4 months ago4 years, 4 months agoHi @Randy-Fridlund – unfortunately, to be considered an eMuseum specimen, the photos must have a scale bar and only include one individual – I also agree that these are brachiopods. Happy hunting!

4 years, 4 months ago4 years, 4 months ago@randy-fridlund This is a brachiopod belonging to the order Strophominida. The flat hinge is the key feature here. Nice find!

4 years, 4 months ago4 years, 4 months ago@samantha-ocon and @randy-fridlund I’m not so sure myself. It looks like it could be a vertebrae with matrix on it but could also be a rock. Where did you find it?

4 years, 4 months ago4 years, 4 months ago@randy-fridlund and @samantha-ocon Yep. It looks like this piece has cellular material in it so ID to a taxonomic group is possible, however, it takes the right tools and techniques to see everything at the right magnification.

4 years, 4 months ago4 years, 4 months ago@samantha-ocon@randy-fridlund Yes, I agree this is agatized wood. We can’t go any further with classification just because there is no cellular material but it is a pretty specimen. I don’t see too many that are so dark with the black and red.

4 years, 4 months ago4 years, 4 months agoSame here, @Randy-Fridlund. These appear to be rugose corals in the bottom right with brachiopods dispersed throughout. Very cool!

4 years, 4 months ago4 years, 4 months agoHi @Randy-Fridlund! I’m seeing rugose corals (also known as horn corals) in the bottom right, and brachiopods (look like shells) in the rest of the specimen. Great find!

4 years, 4 months ago4 years, 4 months agoHi, @Randy-Fridlund! This appears to be recrystallized calcite – this can happen when limestone or shelly materials get exposed to water and dissolve. Over time, the dissolved calcite recrystallizes in empty spaces, which is what we are seeing here. I’m not sure I can make out anything from the pattern that is appearing here.

4 years, 4 months ago4 years, 4 months agoHi, @Randy-Fridlund, very cool specimen! I’m seeing brachiopods in there. If you have any more information about this specimen, that would be very helpful!
Not sure exactly where in Indiana but found in my yard on East side of Indianapolis. Most likely transported from probably further south towards bloomington (?)
That would make sense – you guys are centered on a Paleozoic basin! @Jbauer knows a lot more than I do.
