Both tiger sharks and jaguars (of all things!) are specialist
testudinate feeders. The sharks use sideways head thrashing to 'saw'
through the shells of marine turtles with their serrated teeth, while
jaguars use massive nut-cracker jaw muscles to crack tortoises like
walnuts. Apparently testudinates feature highly in the diets of both
animals.

One wonders whether Thylacoleo ever indulged in the occasional tortoise
snack (they certainly had the equipment for it)...
