| The Boreal province persisted from the Jurassic but was less marked, the Tethyan province was well populated with characteristic benthos. |
| For example, Hallowell found the bear cult was linked strictly to hunting success among the northern Boreal foraging societies. |
| The Cardioceratidae were virtually the only ammonites in the Boreal area, to which they were confined. |
| It lay between the Tethyan and Boreal realms and contains megafaunal elements of both. |
| Cape Cod is also a well-known faunal break that separates the Atlantic Boreal fauna to the north from the Atlantic Temperate fauna to the south. |
| These societies are south of Hallowell's focus of study, the northern Boreal area of North America. |
