Description

W. H. TWELYETBEES 0¥ A NEW THEEIODONT REPTILE.
541
Portion of Upjper Jem (right side) of Cliorhizodon orenbur
gensis, Twelvetrees, Nat. size.
i. Incisor.
c. Canine.
m
m 1-10. Molars.
Proceeding to the canine a fine recurved tooth is exhibited (c).
It is thickest at the base of the crown and somewhat compressed
laterally, though less so than the canines of any other Theriodonts
that I have seen. Its posterior edge bears no sign of serration or
crenulation. The interior is too minerahzed to show reliably details
of structure. Its exterior is faintly marked longitudinally. The
root not being split quite in the median plane, the pulp -cavity is not
displayed ; but the form of the socket and of the implanted fang is
instructively shown. The former is a cavity slightly narrowing
towards its closed termination, and the root follows the same shape.
The significance of such mode of implantation has been finely shown
by Prof. Owen in his description of fragmentary indications of a
huge kind of Theriodont reptile (Titanosuchus ferox, Ow.) from the
Cape of Good Hope*. The present fossil is a remarkably good illus-
tration of the views propounded in that memoir, and I am greatly
indebted to its illustrious author for the guidance thereby afi'orded
me. Not only the canine, but the molars too, which differ from the

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.
