    Definitely Vinlandostrophia–the three costa in the pedicle sulcus and three costa on the brachial fold give it away, right? Thanks to the Dry Dredgers’ website for the great photos that helped with the ID (@bheimbrock, @jkallmeyer, & John Tate!). http://drydredgers.org/brachplaty.htm

    • Yes, and it looks like Vinlandostrophia ponderosa. Other species of Vinlandostrophia have different numbers of weak and strong plications. I can’t stress enough, though, that when identifying a fossil, particularly from photos, knowing the geographic location and site details are very important to correct identification. But then, I think I’m preaching to the choir here. Thanks for asking and for the compliments on the website (http://drydredgers.org), @llundgren.
