Not really but sort of. There isn't really an ear shape that I see, but you can see the tendency of the glass pulling to the center of the marble which, often in combination with a shorter stream fold, tends to make the ear pattern. Same concept as what makes the buttcrack pattern on a JABO but Heaton had a bit longer stream so the ingot curled around more making an ear shape instead of flat on itself making the buttcrack (which Heatons can do sometimes anyway). Same reason Cairo has the "C" shape so often.
