Deliberately overly festive for my talk in May.

The remains of Terminal Pleistocene megafauna in North America represent a continent-wide case study in understanding the taphonomic processes that affect bones, and the use and reuse of bones among some of North Americas earliest inhabitants. The complex dynamics of bone fracture, bone degradation, and the effects of natural and cultural taphonomic processes present a challenge for interpreting the nature of fractured and fragmented zooarchaeological material in North America. The role of the environment in affecting bones and their suitability for use and reuse is profound. Natural processes affect the preservation of bones and their suitability for use, which presents an interpretive challenge for archaeologists examining fractured and fragmented remains. This paper seeks to explain, describe, and resolve some of the problems inherent in assessing and understanding the use and reuse of bones as raw materials, using evidence from two Terminal Pleistocene sites in North America (Owl Cave in Idaho, and the Inglewood site in Maryland) as case studies that highlight the cultural, environmental, and interpretive differences that are manifest in zooarchaeological (and paleontological) assemblages” (read more/open access).

Degenerative changes of superior articular facets in lumbar vertebra (spondylarthrosis lumbalis).



Cribra femora - porotic bone area on the anterior collum femoris - in a child (12 years old). This kind of pathological change usually indicates metabolic disorders, such as anemia.


This 9,000 year old trabecular bone is so fragile but so structurally preserved.

The search for the graves of the knights of Grunwald will begin this fall


Where exactly was the Grunwald battle fought, and is there a chance to find the graves of the knights at Grunwald - archaeologists will look for answers to these questions in autumn. The study will be a joint project of researchers from Poland, Denmark, Norway and Lithuania.

Wait, what?

Calling all lady scientists!


We want to create an index of the lady scientists on Tumblr, much like shychemist did for all scientists.  (Have we thanked you lately?!)  However, it’s a bit more challenging as not all of you announce your gender on your blogs.  So, if you identify as a woman/female,* let us know if you want to be included!

*Obviously we don’t want to be exclusionary.  This is just our cause, to give women more visibility in the sciences.  I believe that seeing a great long list alone would be encouraging to any aspiring female scientist.
