Lone Hunter Posted March 11, 2021 Share Posted March 11, 2021 Found all these in the same place, north Irving ( Dallas County) in eroding drainage canal, lots of shale and concretions and neat little rocks you crack open with surprise inside. Is the small one Metoicoceras? Hard for me to differentiate that and Calycoceras, which the bigger one looks like to me but they wouldn't be in the same place, correct? And the little guy a Heteromorph maybe? I seem to find a lot of those. My favorite part of these is the suture mark patterns. 3 Link to comment Share on other sites More sharing options...
