but which occur in the formations either above or below, are similarly absent
at these distant points of the world. In the several successive palæozoic formations of Russia, Western Europe
and North America, a similar parallelism in the forms of life has been observed by several
authors: authors: 1859 1860 1861 1866 1869 | authors; 1872 |
so it is, according to Lyell, with the
several several 1859 1860 1861 1866 1869 | several 1872 |
European and North American tertiary deposits. Even if the few fossil species which are common to the Old and New Worlds be
kept wholly out of view, the general parallelism in the successive forms of life, in the stages of the widely separated
palæozoic and tertiary
periods,
would still be manifest, and the several formations could be easily correlated. |

These observations, however, relate to the marine inhabitants of distant parts of
the world: we have not sufficient data to judge whether the productions of the land and of fresh water change at distant points
in the same parallel manner. We may doubt whether they have thus changed: if the Megatherium, Mylodon, Macrauchenia, and Toxodon had been brought to Europe from La Plata, without any information in regard to their geological position, no one would have suspected that they had coexisted
with still living sea-shells;
but as these anomalous monsters coexisted
with the Masto- don
and Horse, it might at least have been inferred that they had lived during one of the latter
tertiary stages. |

When the marine forms of life are spoken of as
having changed simultaneously throughout the world, it must not be supposed that this expression relates to the same

or even that it has a very strict geological sense; for if all the marine animals which live at the present day
in Europe, and all those that lived in Europe during the pleistocene period (an enormously
remote period as measured by years, including the whole glacial epoch),
were to be
compared with those now living
in South America or in Australia, the most skilful naturalist would hardly be able to say whether the existing
or the pleistocene inhabitants of Europe resembled most closely those of the southern hemisphere. So, again, several highly competent observers
believe
that the existing productions of the United States are more closely related to those which lived in Europe during certain later
tertiary stages, than to those which now live here;
and if this be so, it is evident that fossiliferous beds

deposited at the present day 1859 1860 1861 1866 |

I think,
be little doubt that all the more modern
marine
formations, namely, the upper pliocene, the pleistocene and strictly modern beds, of Europe, North and South America, and Australia, from containing fossil remains in some degree allied, and from not
