| Summary: | Several non-invasive methods are
common practice in natural sciences today. Here we present how they can be
applied and contribute to current topics in cephalopod (paleo-) biology.
Different methods will be compared in terms of time necessary to acquire the
data, amount of data, accuracy/resolution, minimum/maximum size of objects
that can be studied, the degree of post-processing needed and availability.
The main application of the methods is seen in morphometry and volumetry of
cephalopod shells. In particular we present a method for precise buoyancy
calculation. Therefore, cephalopod shells were scanned together with
different reference bodies, an approach developed in medical sciences. It is
necessary to know the volume of the reference bodies, which should have
similar absorption properties like the object of interest. Exact volumes can
be obtained from surface scanning. Depending on the dimensions of the study
object different computed tomography techniques were applied. |
