Anoplosaurus
Seeley 1879
Anoplosaurus est un genre fossile de dinosaures ornithischiens herbivores de l'infra-ordre des ankylosauriens et de la famille des nodosauridés. Il est rattaché à la sous-famille des struthiosaurinés par J. I. Kirkland et ses collègues en 2103. Il a vécu en Angleterre où ses restes fossiles ont été découverts en 1872 dans les sables verts de Cambridge datés du Crétacé supérieur (Cénomanien), soit il y a environ entre 100,5 et 93,9 millions d'années.

PLATE X X X I ~ r.
The vertebral column of Anoplosaurus c~rto~ot~s.
Fig. l. Left lateral aspect of third to seventh cervical eentrums, showing how
the bodies of the vertebrae increase in depth from before backward,
and indicating at the upper anterior corner of each an attachment
for a cervical rib.
1 a. Visceral aspect of third (?) cervical vertebra, showing flattened and
rounded under surface, and expansion towards the anterior end.
Fig. 2. Left lateral aspect of fourteenth to eighteenth eentrums of the series,
showing the somewhat compressed appearance of upper parts of the
bodies of the last five dorsal vertebra.
2 a. Visceral aspect of the last dorsal vertebra, 1~o. 18.
2 b. Posterior (?) articular end of the same centrum, No. 18.
3. The sacrum, showing the neural or superior surface, and giving evi-
dence of the great expansion of the spinal cord in the region of the
second and third sacral vertebra. The outlets for the escape of the
sacral nerves at the sides of the centrum are best seen in the first
three vertebrae.
4. Dorsal surface of vertebral end of a sacral rib, showing the massive end
for attachment to the sides of the centrums of the second and third
vertebrm. Its worn upper surface gave attachment to the neural
arch.
5. Left lateral aspect of a sequence of six early caudal vertebrm numbered
25 to 30, showing decreasing depth of the centrum posteriorly, and
diminishing size in the surface for the attachment of the sacral rib
which remains in union with the 30th vertebra. The chevron facet, e,
also diminishes in size.
5 a. Posterior articular surface and facet for the chevron bone of the
vertebra ~No. 26.
