4 years, 11 months ago4 years, 11 months agoHi James,
Your formation is older. It would be equivalent to the Lodgepole formation which is part of the Madison group in Montana. I also have some Productids from that formation too.
The examples of Echinoconchus I saw were from Kansas coming from Penn age rocks.

4 years, 11 months ago4 years, 11 months agoHi James,

Where as my specimens have spines projecting off the pedicle valve and pedicle opening. These spines are long. I have seen these spines…[Read more]

5 years ago5 years agoHey @mackenzie-smith, thank you for the reply. I had looked at Dicotylophyllum hansonium from Peppe and Hickey 2014. At first I thought my specimens matched until I brought the photo in the report to a 100 res. and notice some differences between the example and mine. This is the best match considering leafs of a tree can be different in sh…[Read more]
