| resource partitioning among top predators in a miocene food web. | the exceptional fossil sites of cerro de los batallones (madrid basin, spain) contain abundant remains of late miocene mammals. from these fossil assemblages, we have inferred diet, resource partitioning and habitat of three sympatric carnivorous mammals based on stable isotopes. the carnivorans include three apex predators: two sabre-toothed cats (felidae) and a bear dog (amphicyonidae). herbivore and carnivore carbon isotope (δ(13)c) values from tooth enamel imply the presence of a woodland ec ... | 2013 | 23135673 |
