i'm pretty sure he understands that, and even if not, the second row of teeth in LEP genus is more or less irrelevant in that question.
no time to get into the details but i'll post a link to an actual gar species-wide PSI study that was done (including a fossil species) soon. you asked about tooth replacement...they don't necessarily migrate like in sharks, but they are replaceable in most cases. the crazy ones are the spotted gars we find in the wild which have huge fangs that have grown up from the lower jaws and THROUGH the upper jaw and protrude from the top of the snout...will have to dig up some pics...Richard and i have seen these "saber-tooth" gars here and there in our field work--
