Having already described him in most of his present habitatory and anatomical peculiarities, it now remains to magnify him in an archaeological, fossiliferous, and antediluvian point of view.
But not alone has this Leviathan left his pre-adamite traces in the stereotype plates of nature, and in limestone and marl bequeathed his ancient bust; but upon Egyptian tablets, whose antiquity seems to claim for them an almost fossiliferous character, we find the unmistakable print of his fin.
It will be much more convenient to discuss this question in the chapter on the Imperfection of the geological record; and I will here only state that I believe the answer mainly lies in the record being incomparably less perfect than is generally supposed; the imperfection of the record being chiefly due to organic beings not inhabiting profound depths of the sea, and to their remains being embedded and preserved to a future age only in masses of sediment sufficiently thick and extensive to withstand an enormous amount of future degradation; and such fossiliferous masses can be accumulated only where much sediment is deposited on the shallow bed of the sea, whilst it slowly subsides.
In this great class we should probably have to descend far beneath the lowest known fossiliferous stratum to discover the earlier stages, by which the eye has been perfected.
Vast, and scarcely comprehensible as such changes must ever appear, yet they have all occurred within a period, recent when compared with the history of the Cordillera; and the Cordillera itself is absolutely modern as compared with many of the fossiliferous
strata of Europe and America.
beds extend from half km south of the village to the Soan River.
In its middle part greenish grey to grayish shale has two interclations of thin bedded arenaceous unfossiliferous limestone and one medium bedded poorly fossiliferous
The Jahrum Formation in this section lithologically consists of fossiliferous
limestone and beige to gray medium to thick layered dolomitic limestone.
The identification of this rock was found to be dolostone (a fossiliferous
sandy dolomite and fossiliferous
sandy limestone) the rocks that form the upper confining unit for the Floridan Aquifer System.
Significance of fossiliferous
Middle Cambrian rocks of Rhode Island to the history of the Avalonian microcontinent.
This paper presents an example of how a common type of decorative building stone, fossiliferous
limestone enriched with coiled cephalopods, can be used to teach the concept of functional morphology.
Each cycle began with deposition of carbonate pelletal mud, micrite, followed upward by fossiliferous
calcarenties and an upward shoaling oolite bar.
