Hello @david-powers! Sorry for the delayed response. It appears to me the best match is Dicotylophyllum hansonium from Peppe and Hickey 2014. However, there do seem to be some differences. Either you fossil has better preservation of the tertiary fabric than their specimens or it’s different. One of their figured specimens appears to have asymmetrical venation off of the secondaries (though this could be an artifact of preservation) which I did not see in yours. But the palmate, acrodromous venation and toothed margin all fit. This genus is a morphogenus, if I recall correctly, and so we don’t know what it’s related to. Hope that helps!
