Preheat oven to 300 degrees. On greased baking sheets, arrange the pecan halves in groups of three, end to end with the flat sides down. Place a caramel on top of each cluster. Place in the oven until the caramels soften, about 5 to 8 minutes.
Remove from oven and flatten the caramels over the pecans with a butter spoon. Cool slightly. Melt the chocolate in the top of a double boiler over simmering water. Dip the turtles into the chocolate and cool on wax paper. Store in tightly covered containers in a cool place. Pack turtles in decorative tins to give as gifts. Makes 50 turtles.
