In the photograph below of Smithsonian specimen USNM 155408, the incisor
attrition as described by Moeller is clearly apparent. The rills
are no longer evident, and there is central mergence of the dentine in
all of the lower incisors. In life, this thylacine was displayed
at the National Zoo in Washington, DC, and died aged 7 years, 5 months
and 3 weeks. |
