Because the embryonic whorls of all the forms are smooth, carinate, or undulated
, but not spinose, we infer that the spinosity is a later degree of development and
that the relatively smooth shell represents approximately the ancestral form.

When, therefore, B and B' are compared together, it is found that each has the
same degree of spinosity, but that B' has twice the degree of asymmetry of L
which B has ; and when 0 is compared with B' it is found to have the same degree
of ...

Predator-Prey Interactions in the Fossil Record
Spinosity The last and perhaps less ambiguous morphologic trend predicted by
Vermeij (1977) and Signor and Brett (1984) is an increase in the frequency of
taxa with spines; spines may also be predicted to increase in length and
sharpness.

Deiphon's extreme spinosity suggests it was a swimmer-floater rather than a
bottom-dweller. Spinosity increases surface area without adding weight, thus
enhancing buoyancy. This specimen is about 27 mm long. Punctuated
equilibrium.

Advances in Trilobite Research
The evidence for this mode of life comes from two sources, the optics of the visual
system, and the extreme spinosity of the tiny body. Ctenopyge ceciliae (Clarkson
and Ahlberg, 2002) occurs in great numbers, at one locality only, in calcareous ...

Journal of the Royal Society of New Zealand
The "incipient" spinosity referred to in some older descriptions should more
correctly be described as "remnant" spinosity. The small spine-bases visible on
most fossil specimens are not the forerunners of spines but the only portions
remaining ...
