I've put discussion of the 'vertical clinger' model into the
_Archaeopteryx_ MS [in press] together with comparisons with
parulids, campephilin woodpeckers and pygmy parrots - Chatterjee's
and Palm's proposal that dromaeosaurids were well-suited for trunk
clinging is poorly founded. Palm's diagrams show little
dromaeosaurids climbing down tree-trunks head-first: that's why the
animals in my drawing are doing the same thing. BTW the
_Archaeopteryx_ MS is another rambling historical discussion.. it
does not include any real science.
There is apparently an old restoration of a climbing sloth-like
_Deinocheirus_, perhaps in a French publication. Has anyone seen it?
