Hi Morphmetters, happy 2016!
I am pleased to announce the availability of two datasets (projects) on
morphosource.org that may be of interest. There is no need to login to
see these, just click on the PROJECT tab and go to either _Delson
Primate scans_ or _Retrodeformation by algorithmic symmetrization (Delson)_
I (and colleagues) have been CT-scanning a variety of primate specimens,
mainly skulls of extant cercopithecids but other taxa and elements as
well. These are being posted to Morphosource for open access, no
permission necessary, for use in research projects. The American Museum
of Natural History Departments of Vertebrate Paleontology and Mammalogy
support this access, so please download anything of interest. More
specimens will be added as we prepare the files (including some surface
files). There are a number of other primate CT datasets on Morphosource
as well.
Of possibly more interest to this list is a smaller set of surface scans
we used in a study of "retrodeforming" deformed specimens using a GM
approach. As described in
Tallman, M., Amenta, A., Delson, E. Frost, S.R., Ghosh, D., Klukkert,
Z.S., Morrow, A. Sawyer, G.J. 2014. Evaluation of a new method of fossil
retrodeformation by symmetrization: crania of papionins (Primates,
Cercopithecidae) as a test case. /PLoS One/. Vol. 9(7). PLoS,
doi:10.1371/journal.pone.0100833,
we tested our algorithmic method by manually deforming partial plaster
casts of a papionin cranium, so that we knew the original "correct"
shape. I have now posted the surface scans of the original specimen
(cast), the deformed versions and our retrodeformed results. We hope
that colleagues will make use of these scans to test their own
retrodeformation methods. We are continuing this project (see Tallman et
al. abstract in Society of Vertebrate Paleontology 2015 Annual Meeting
Program and abstracts, p. 222; available at

and related approaches and will make additional data available as
publications are completed.
Enjoy, Eric
