Addendum to UPDATE (Maryland tracks)
Sorry, I neglected to mention that in the two recent Sauropod manus
track finds (as in six others of the dozen or so Sauropod manus tracks found
here in Maryland), impressions of ALL FIVE DIGITS of the manus are visible
as distinguishable units. Sorry we are not allowed to include drawings or
photos to this list, but for the lovers of sauropods who care: In these
better manus impressions, the patterns produced by digits 1 and 5 are of
SUBSTANTIALLY DIFFERENT SHAPE, one from the other. This difference is
consistent in all the seven manus prints that record them. If you haven't
learned anything about distinguishing left-side from right-side in
good-quality sauropod manus impressions, the distinction can now be made by
recognition of the differences in the impressions made by digits 1 and 5,
viewed separately and out of a track-way (series of prints).
The how-to (evidence of this) will be published, but WHERE is yet to be
determined. I'll keep you posted.
If any of you Sauropod track experts are listening, we can discuss this
matter of distinguishing right from left OFF-LIST, if you're interested.
This degree of this distinction may have a correlation with the animal's
speed (within limits, of course), but I do not believe it to be totally
kinetics-dependent. It seems linked to both form and dynamics.
