Inferences regarding the biology of extinct taxa are often founded primarily
on cladistically-based phylogenetic hypotheses. However, these inferences are
frequently inconsistent with the morphology and physiology of modern animals. I
suggest that reference to the biology of modern animals might be a more
appropriate tool to aid in the reconstruction...
Llamas (Lama glama) appear to have predisposing anatomical features for developing
otitis media such as a long and narrow external acoustic meatus and a trabecular
tympanic bulla. However, there is limited information available about the morphology of
the ear in this species. The aim of this study was to evaluate...
