I purchased some Ptychodus teeth and I can not determine the exact ID on my own. They are smaller than P. whippeli or P. mortoni teeth I have and bigger than the single P. anonymous tooth I have though that is the species I originally though, and still think these are. They are from the Kamp Ranch section of Eagle Ford in Texas. I consulted a very well put together ID guide here but am still just not sure what I have, other than nice Ptychodus teeth lol
Any help would be appreciated.
