Hilderbrand and colleagues wanted to determine the feeding ecology of the extinct European cave bear to determine whether individuals were herbivorous. To investigate this question, they
A) examined the structure of cave bear teeth and jaws.
B) measured the rare chemicals (such as ferosine) in the cave bears and compared them to the chemical composition of preserved remains of different food sources.
C) measured the nitrogen isotopic composition of the cave bears and compared it to the isotopic composition of the different food sources.
D) measured the ratio of carbon and nitrogen isotopes in cave bear bone samples and compared it to the ratios found in other known species whose diets were well known.
