2nd Grayson/Mainstreet ammonite I’ve ever found

I found my 2nd ever ammonite in what I’m calling the Grayson formation, based on Mancos app showing solid Grayson, though it’s fairly close to the paw paw. Tarrant County, TX. I’m not well educated on Main Street though, so maybe that fits in here somewhere? Either way, I’ve been to this spot numerous times, lots of cymatoceras nautiloids and I got my biggest turrilites from this spot too. I was thrilled to find a 2 pound, 5.5 inch ammonite. I am GUESSING it might be mortoniceras parinflatum? If anyone can confirm or correct, much appreciated! I used the Kennedy paper on Grayson/Mainstreet cephalopods. I can’t wait to clean it up with air abrasive/air scribe to see what the center looks like.
