Principal parts of a Calamites plant (From George's Basement)
We have a sweet little Annularia radiata from Mazon Creek for this week's Fossil Friday. Annularia is the foliage for Calamites. Annularia radiata is very common in the terrestrial localities of the Mazon Creek fossil deposit.
This specimen was collected from the Pit 3 locality in the spring of 2025. It was opened via the freeze/thaw method.
