“I shall kill no albatross”

Dispatches from the field with Ariel

This month I am conducting research at the Museum of the North for my dissertation. At the Museum, I am examining several bird assemblages that were excavated and analyzed during the late 1960’s and early 1970’s. All of these assemblages are from Amchitka island, which is the southernmost of the Rat Islands group in the Aleutian Islands.

As these collections were previously analyzed, my work here focuses on checking to make sure that the prior taxonomic ids were correct and seeing if there were any cut marks, burning, or pathologies that may have been missed in the prior analysis.

So far, there have been some interesting results!

One of the most interesting bones I’ve looked at was this albatross humerus that was COVERED in cut marks. Normally when we see cut marks on bird bones from the Aleutians there are only a a few present. As you can see there are cut marks all up and down the shaft of the bone. Was somebody practicing their cutting techniques? Were they removing feathers from the wing? Was the knife not sharp enough?

Also in the albatross assemblage, I found this skull that has been burned. Part of the burned area is missing (it was likely lost either while it was sitting in the ground for several thousand years or post-excavation).


Ultimately, what caused each individual cut mark or burned bone has been lost to time, but by analyzing these collections as a whole, I will be able to piece together how each species was being exploited.

This research was made possible by NSF Dissertation Research Improvement Grant #1853169 (P.I. Chevral/co-PI Taivalkoski).

Smitten with the Smithsonian

Dispatches from the field with Dr. Funk and Ariel

The success of this trip is attributed not only to the hard work of Dr. Funk and Ariel but to all of the students who have worked in the lab and made it possible to do this extensive bone analysis. The background lab work they accomplished in the 8 months prior to the trip provided a strong basis of fundamental knowledge and research.

The trip to the Smithsonian was incredibly successful for the NSF project as well as for mentoring; because of this experience, Ariel is poised to do her dissertation research. From this experience she has gained ‘how to’ knowledge and capabilities, contacts within the museum, knowledge of the available reference skeletons, and navigational bearings through the dense maze of rooms, libraries, and hallways.

During the four short weeks we were graciously hosted by the Smithsonian Museum of Natural History Birds Division, ZooArch Lab researchers analyzed over 5,000 bones. “We had aggressive goals for the analysis,” said Dr. Funk, “and because the collections of the Birds Division are so well suited to Aleutian avifauna research we were able to analyze specimens from all of the bird families we brought with us.”

Taking full advantage of their opportunity, our researchers were able to attend to some additional projects during their stay. Ariel was able to give attention to her bird bone pathology study and both researchers think they may have identified an extinct cormorant in the prehistoric bird bone collection!

During this research Ariel and Dr. Funk have identified many species that are rare today but were evidently abundant during the occupation of the Margaret Bay site (UNL-048) at about 4700 years ago. Our researchers rented an apartment on Capitol Hill, and they walked to work every day past the Capitol, the Senate offices, and down the Mall. Working on research about environmental change and actually seeing shifts in avifauna species over time in a place where environmental decisions are being legislated renews our researchers’ motivation for this project and reminds us that what we are doing is critically important.

Faunal Pathologies and the Puzzles They Pose

Authored By: Shannon Clark ’18 Zooarchaeology Lab Social Media Intern

Faunal pathologies are the effects of disease or injury on animal bones. The pathologies, or bone deformations, we find on animal bones give us IMG_0023insight into the life path of that animal. Patterns in bone abnormalities, and the contrasts and similarities between them, can inform us about environmental conditions, population health, and human involvement with animals .

In our Zooarchaeology lab, we identify pathologies in animal bones when we analyze the faunal remains excavated from archaeological sites. Some of these pathologies have known origins: injuries for example, result in distinctive anomalous bone growths. Other bone pathologies are more difficult to source.. Understanding these abnormalities involves a great deal of research and investigation, beginning sometimes with what we know about the formation of bone pathologies in humans. Zooarchaeological pathology research often crosses disciplines and involves discussion with veterinarians, veterinary texts research, and researching the results of earlier archaeological faunal analyses.

The study of zooarchaeological abnormalities in birds is complicated by the fact that pathologies sometimes are overlooked. This can happen because of limited time to perform analyses or because the identification of pathologies is not relatable to the research taking place. For whatever reason, there is a lack of avifauna pathology reference material for comparison during zooarchaeological analysis. In our lab, Ariel Taivalkoski is working to first identify, then define the source cause for pathologies.

Her process begins by identifying pathologies on bird bones. She photographs each pathology to create a comparative, visual data set which will later serve as a comparative collection for her work and research in other Zooarchaeology labs. Pathologies reveal secrets of the past that would otherwise remain unknown. As with any scientific research the answer to questions requires patience and determination. Stay tuned into our blog for further posts on the pathologies as we uncover them here in the UB Zooarchaeology Lab.
