STRIATIONS "Fine raised lines on the surface of the
crown"
Some terminology is troublesome because it is
comparative. A tooth may be described as having "weak striations", the
question becomes, weak compared to what? To understand this terminology
better I resorted to purchasing a few inexpensive specimens to use as a guideline.
For consistency all specimens are in excellent to
pristine condition.
Very weak
Easy to miss, appears as very fine wrinkles, strong light or
magnification needed to be sure.
aka longitudinal wrinkles.
Odontaspis reticulata
Weak
Clearly visible, but still has a wrinkled look to it
aka longitudinal wrinkles.
Carcharias taurus
Moderately strong
Appears more like fine lines then wrinkles, or a mixture of
both.
aka fine longitudinal striations.
Striatoloamia macrota
Relatively strong
Very obvious, the lines become deeper and dominate.
aka longitudinal striations .
Carcharias holmdelensis
Strong to coarse
Dominates the lingual side of the crown, not easy to miss.
aka distinctive longitudinal ridges
