3 years, 7 months ago3 years, 7 months ago@shannon-olczak@mackenzie-ross-2 I believe this is a nodule from Mazon Creek (Formation name)? It would be Late Carboniferous (Pennsylvanian). Are these two separate specimens or are they two halves of the same specimen? If they are different, the first and second appear to be the seed fern (not true fern) Alethopteris. However, the last picture…[Read more]

3 years, 7 months ago3 years, 7 months ago@mackenzie-ross-2 and @shannon-olczak sadly I cannot. All I can say is that it’s wood. Identification for petrified wood requires preserved cellular details and prepared slides via thin-section or cellulose acetate peels. I’m sorry, it’s just the nature of wood ID.

3 years, 7 months ago3 years, 7 months agoGreetings@diane-soderman ! I agree with @mackenzie-ross-2 about those being a sedimentary rock. Also, if you are in Kingsbury County then you are in the Pierre Shale Formation. The Pierre Shale covers most of eastern SD and in primarily marine late Cretaceous sediments. Ferruginious nodules, like the one you found, are common in the PSF. I have…[Read more]

3 years, 7 months ago3 years, 7 months agoGreetings @al-halt ! I agree with @mackenzie-ross-2 about the photos. At first glance it appears to be an iron nodule though.

3 years, 7 months ago3 years, 7 months ago@diane-soderman and @mackenzie-ross-2 I agree with @bill-heim that there is wood in the second picture. I also think that there is wood impression in the first. But because there is no cellular detail we won’t know what type of plant it was.

3 years, 7 months ago3 years, 7 months ago@mackenzie-ross-2 and @al-halt I agree with @leonardo-miranda that this is petrified wood. However, we can’t know which plant (family or even phylum) because there is no cellular detail preserved.To ID wood to a lower taxanomic group, you need good preservation of the cells.
