First is this one - which was labeled as P. benedini - measures just over 1”/3.25cm The second - thinking A. Grandis? Also just over 1”. And finally - forgot to take more pics of this one, but it’s closer to C. Planus, which I don’t believe exists in SC, so I’m not sure what it is. Person I got it from confirmed they found it themselves - also just over 1”. @Al Dente @hemipristis @Shellseeker Any help would be appreciated! I like Parotodus for the first, and A. grandis for the second. The third is tricky. I'm thinking Isurus retroflexus lateral based upon the thin, translucent edges of the blade, the labial root protrusion, and the lingual root "shelf" (faint though it is) Edited July 13, 2023 by hemipristis 1 2 1 'Those who cannot remember the past are condemned to repeat it.'
