TOS+ is telling me that the Elasmosaurus has a CMD of 29, while the PRD lists it at 30.
CMD = 10 + Base attack bonus + Strength modifier + Dexterity modifier + special size modifier
10
+7 (Base attack bonus)+8 (Strength modifier)
+2 (Dexterity modifier)
+2 (special size modifier - Huge)
====
29
Unless I missed something (please let me know!), this appears to be an error in the Bestiary.
