Gland detection in glyptodont bones
The glyptodont belongs to the group of placental mammals. Very few specimens were found in Argentina and Uruguay exhibiting a protrusion, as an inverted spherical cap over the shell. It is not clear yet, if this protrusion corresponds to some injury made by some aggressor or if it is a cavity for accommodating some gland. The last assumption would give rise to a new species of glyptodont. Scanning electron microscopy and computed tomography have been performed on samples taken both from the “normal” part of the shell and from the protrusion. These results show cavities on the protrusion part of the shell that could belong to gland channels, that could be the pipes for the transport of the production of the gland allocated into this protrusion. It is critical to explore if these cavities are really the channels of a gland and Neutron Vibrational Spectroscopy could give information about their functionality. So in order to analyze in detail the mineral and organic content (mainly hemoglobine, with a principal band at 3500 cm-1) of these normal and protrusion parts, an Inelastic neutron scattering experiment on LAGRANGE is proposed. For this study we ask for 3 days of beamtime.
