This widespread Mesozoic species is not abundant in <strong>the</strong> <strong>Raritan</strong><br />
formation, being only recorded from <strong>the</strong> single locality <strong>of</strong><br />
Wo_)dbridge, where it is not common. This relative rarity is<br />
probably to be explained by local climatic conditions due to altitude<br />
9r to <strong>the</strong> character <strong>of</strong> <strong>the</strong> soil and its water content and<br />
<strong>the</strong>ir effect upon relative humidity. Of course, such an explanation<br />
is largely speculative. We do know, however, that Sequoia<br />
twigs are about <strong>the</strong> last fragments in floating vegetable<br />
debris to disintegrate, and that <strong>the</strong>ir remains are fotmd in deposits<br />
in which <strong>the</strong> associated vegetation is reduced to an unrecognizable<br />
mass, so that it is safe to predicate that gequoia<br />
Reichenbachi did no_ grow near <strong>the</strong> place where <strong>the</strong> <strong>Raritan</strong><br />
sediments were being laid down and that such specimens as are<br />
preserved were floated into <strong>the</strong> <strong>Raritan</strong> basin by streams, perhaps<br />
from tbe uplands where <strong>the</strong>y grew. In <strong>the</strong> succeeding<br />
