| These rocks are also of biogeographic interest because unlike truly allochthonous terranes they are parautochthonous with respect to the craton. |
| Differences in abiotic factors such as differential effects of glaciation and sea-level changes on land and in the sea may also greatly influence biogeographic patterns. |
| Ice Ages Global patterns of continental icesheet expansion and recession, isostasy, sea-level changes, and associated biogeographic records. |
| Russell reminds readers that we do not know the biogeographic origin of birds, or theropods, or dinosaurs. |
| This ancestral biogeographic distribution encompassed a much broader range, comprising Siberia and southern Europe-northern Africa. |
| The biogeographic patterns of vicariance and range expansion may also provide insight to the mechanics of this extinction event. |
