-- Formal description of Dromaeosauroides bornholmensis n. g. n. sp.,
mentioned on DML in previous posts discussing another paper
(http://www.cmnh.org/dinoarch/2003Mar/msg00348.html) holotype and only
specimen: 1 tooth (Geological Museum Copenhagen), from Lower Cretaceous
Jydegaard Formation (Berriasian-Valanginian); Robbedale, Isle of Bornholm,
Denmark.>

  This is not the original description of this form, however. The taxon
was formally described and named in Bonde and Christiansen, 2003, New
dinosaurs from Denmark, _Comptes Rendus Palevol_ 2: 13-26.

  The holotype is MGUH DK No. 315, a presumably mesial lateral crown
lacking root and bearing distinct lingual AND labial wear facets apically,
though the labial facet is longitudinal on the crown face, and the
linguals are semi-ovate and apical, appearing to have been worn in a
for-aft direction versus the vertical, oral direction of the labial one.
The tooth is incredibly compared to only *Dromaeosaurus albertensis* with
honorable mention to *Nuthetes* from the EK Purbeck fauna, and diagnosed
by the much smaller denticles than *Dromaeosaurus* and its 60 my
difference in age from that taxon. Otherwise, the tooth is unremarkable
aside from the wear facets which are not present in such a pattern or as
extensive as in *D. bornholmensis*. The authors state that it is
"unlikely" the genus *Dromaeosaurus* spanned 60 my, so they coined a new
name.

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
