    Came across this odd fossil in a Chicago city park. Other similar boulders nearby had woody plant fossils. Curious what y’all can make of this one. 1st image is a stereophoto.

    Apologies that your post has gone unanswered for so long, @asa-kaplan.  @rleder has a background in paleobotany; what do you think Ronny?

    @asa-kaplan, Hi Asa, upon first look it appears like a fossil Carya, but that would not match with Pennsylvanian age, so I suggest that you might have a pseudofossil here.
