Shark Teeth Identification (Cretolamna?)

[AlexMcCarthyWX]

Below are five shark teeth I am trying to make sure I have identified correctly. Teeth 1-4 were found in North Myrtle Beach, though I do not know where tooth 5 is from. I believe that #2, #3, and #4 are C. Appendiculata, but am not confident in that. I wonder if #1 is as well, the shape seems a bit different in my opinion. Thanks!

I think there is a good possibility that #1 through #4 are Cretalamna. The last tooth might be Carcharias, depending on age and location found.

The pictures for teeth 2 thru 4 are not very good and important tooth features that could affect the ID (Like nutrient grooves, striations on the crown, ornamentation on the crown etc.) can't be seen.  Tooth 5 is a sandtiger tooth.  Without a location where found and/or age of the formation where it came out of there are too many possibilities to try to ID it further to a genus/species.  I'm not familiar with the age of the formations at Myrtle beach.  If there isn't a Cretaceous formation there, then tooth 1 is Cretalamna or Otodus.  If there is Cretaceous Formation there, there are a number of other possibilities.  Teeth 3 and 4 could be Cretalamna but with the size difference of the cusplets, they could also be sand tiger teeth (can't tell from the pictures).  Tooth 3 does look like a Cretalamna tooth.

 

 

Edit:  Based on @sixgill pete Don's reply below that "the Myrtle Beach area has Cretaceous PeeDee Formation.", that changes my reply.  Tooth 1 couldn't be Otodus, but I think there are some other Cretaceous possibilities in addition to Cretalamna.  Teeth 3 and 4 wouldn't be sand tigers, so teeth 2-4 would be Cretalamna.  Based again on a Cretaceous age, tooth 5 could be further identified to the genus Carcharias.

@MarcoSr , the Myrtle Beach area has Cretaceous PeeDee Formation.

 

I believe 1 through 4 are Cretalamna. #5 is a sand tiger, likely Carcharias.

#5 is a Sand Tiger tooth

 

*EDIT* I see Collections Curator has beat me to the Sand Tiger label, great job! I second his opinion.

Good evening everyone and thank you for the additional attention to this post! I am out of town at the moment but will probably post better pictures of those teeth in a few days in case that helps with further identification. Thanks!
