Description

1857..
BUCKMAN — OOLITES.
103
Here, then, we have a total of 43 species, only 1 1 of which are
truly liassic. It should here be remarked that this list does not
include the Ammonites bifrons or the A. Jimbriatus, upon the former
of which Dr. Wright, and, after him, Mr. Hull have laid such stress ;
the truth being, that both Dr. Wright's specimens of these Ammo-
nites (for his matrix was traced) and my own were obtained from as
much as 20 feet below the oolite- sands, in the true micaceous beds
of the Upper Lias Shales, the position of which will be made plain by
the accompanying section of beds at Frocester Hill : —

bands of obliquely-laminated
beds 40

domya 6

6. Upper Lias Shales — very mica-
ceous 20
7. Band of indurated White Lias,
with Am. bifrons and A. Jim-
briatus 1
8. Upper Lias Shales, blue.
Now, if I am right in my interpretation of this matter, Dr. Wright
has gone into the Lias Shales for his proofs that the Cephalopoda-
bed, 80 feet higher, is Lias ; nor is it difficult to understand how he
may have been led into this error, inasmuch as the upper part of the
Lias Shales has become oxidized from atmospheric exposure ; and
besides, on this slope the Inferior Oolite Sands have fallen over them,

This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:
Public domain

This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 70 years or fewer.


This work is in the public domain in the United States because it was published (or registered with the U.S. Copyright Office) before January 1, 1929.

This file has been identified as being free of known restrictions under copyright law, including all related and neighboring rights.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.


Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.
