Perhaps very few Tertiary formations have received a greater amount of attention from geologists and collectors of fossils, during the last forty years, than the Red Crag of Suffolk and Walton-Naze; and it seems singular that so few traces of land life have resulted from so much research. Although in its southern portions it is strictly a marine deposit, yet its distance from shore could not have been very great at any point; but putting aside the few plants and mammalian remains, most of which in the coprolite portion of the Red Crag are derivative, there is little evidence of its proximity. |
