One of the basic tenets of a scientific collection is that the data associated with the specimens is as important as the specimens themselves. Without the “Who, What, Where, When” for a natural history object, it has little research value and becomes a mere curiosity. So we always try to preserve these basic cornerstones of data for each specimen: who collected the object, what is it, and where and when was it collected. These data are entered into our catalog and are recorded on the individual label with each specimen.

Tucked under the scientific name on our standard museum labels is the small heading: “ID by”. This is where we record who originally identified the object. It might not seem terribly important, but it tells us if the specimen was identified by a qualified researcher or not. In short, it informs us how confident we can be that the identification is correct.

 

When I spent time working in our bird skeletal collection, I started noticing small handwritten labels inserted in the boxes of bird bones. These labels seemed to be mostly in the older boxes of bird bones recovered from archaeological sites, and included the species identification and then the initials “A.W.” I wondered who A.W. was and how they seemed to know so much about bird bones. Not having time to pursue this, I kept the initials in the back of my mind and went about other projects.

Then later when accumulating some articles on bird skeletons I began to see the name Alexander Wetmore. I went back for a more thorough look at our collection, a few other labels had his name spelled out.

He obviously was a specialist in bird bones, but who was he?

  • In 1923 and 1924 he was the lead scientist of the Tanager Expedition, a series of five biological surveys to study the flora, fauna and geology in Hawaii and other Pacific islands.
  • In 1924 he joined the Smithsonian Institution as the Superintendent of the National Zoo in Washington, D.C.
  • In 1925 he was the Assistant Secretary of the Smithsonian Institution.
  • From 1945 and 1952 he was appointed as the 6th Secretary of the Smithsonian Institution.
  • He authored numerous publications, including the books A Systematic Classification for the Birds of the World and the 4-volume Birds of the Republic of Panama.
  • Many animal species have been named in his honor, as well as the Wetmore Glacier in Antarctica.

So how did Dr. Wetmore come to take an interest in our collections?

By Marie Swartz, Archaeology Curator

When I heard about Dave’s research on Dr. Wetmore one name came to mind: Robert Goslin. Goslin was what archaeologists refer to today as a zooarchaeologist, a person with an interest in animal bones (also known as faunal remains) found at archaeological sites. Goslin authored multiple articles based upon his analysis of faunal remains present at archaeological sites including Evidence of the Occurence of the Rice Rat in Prehistoric Indian Village Sites in Ohio and Food of the Adena People.

Identifying and contextualizing faunal remains is very useful as it can reconstruct the climatic environments of the ancient past, determine if villages were occupied seasonally or year-round, and identify the diet of people inhabiting the site. Sometimes faunal remains were altered in order to create specialized tools like awls to punch leather, beamers to strip the flesh and fat from animal hide, or fish hooks to well… fish. These objects allow archaeologists to further reconstruct the past.

Tools made from various animal bones are shown, including an awl, a beamer, and a fishhook.

Bone tools found within our Archaeology Collection: an awl made from an animal scapula found at Pearson Village, a beamer made from a deer metatarsal found at Campbell Island, and a fishhook made of animal bone.

It wasn't just Goslin's specialization which made a light bulb go off in my head. Goslin had worked in the Archaeology and Natural History Departments at the Ohio History Connection from the late 1920s through the early 1960s so, naturally, he and Dr. Wetmore were academic peers. I dove into archival research to investigate and discovered numerous letters of correspondence addressed to Goslin from Dr. Wetmore dating between 1941 and 1959.

Based on Dr. Wetmore's responses, it is apparent that Goslin requested assistance in identifying bird remains from five archaeological sites located in Ohio:

1. Feurt Village

Feurt Village is a Fort Ancient culture archaeological site located near Portsmouth. A total of 31 species of bird were identified with Dr. Wetmore's assistance. The site produced the first recorded pre-contact remains of the Ivory-Billed Woodpecker and Lesser Sandhill Crane, prompting Dr. Wetmore to publish two articles in the ornithological journal, the Wilson Bulletin. Other notable species identified include the Passenger Pigeon (extinct), Raven (recovering from extirpation, or localized extinction, in Ohio), and the Greater Prairie Chicken (extirpated from Ohio around 1900).

2. Canter's Cave

Canter's Cave is a rock shelter site located in Jackson, Ohio that was occupied throughout the pre-contact period and used, like many rock shelters, for picnicking and leisure into the 19th and 20th centuries. Found within the same context as pre-contact artifacts, a total of 19 species of birds were identified from the faunal analysis. The most notable being the Mississippi Kite which was again published on by Dr. Wetmore within the Wilson Bulletin. Today the Mississippi Kite is making a return to Ohio with breeding pairs spotted in the Hocking River Valley and Shawnee State Park.

3. Seip Earthworks

Seip Earthworks is a Hopewell culture archaeological site located in Chillicothe, Ohio, and is one of eight Hopewell Ceremonial Earthwork sites currently awaiting inscription onto the UNESCO World Heritage List. Dr. Wetmore identified the Peregrine Falcon from a single maxilla, or the tip of the bird's beak.

 

5. Anderson Village

Anderson Village is a Fort Ancient culture archaeological site located adjacent to the Fort Ancient Earthworks in Oregonia, Ohio. In 1959, Dr. Wetmore returned to the Smithsonian from an expedition in Panama with a package from Goslin awaiting identification on his desk. Inside were the beaks of two Carolina Parakeets, a species that had gone extinct 41 years earlier.

4. Baum Village

Baum Village is a Fort Ancient culture archaeological site located near Chillicothe, Ohio. In 1943, Dr. Wetmore identified the Pileated Woodpecker from a single premaxilla sent by Goslin.

How are Bones Identified?!

It is unusual for complete animal skeletons to be discovered during archaeological excavation. At times only a single bone or very few bones from one species of animal is recovered. For example, only a pelvis and humerus from Canter's Cave was available to Dr. Wetmore to make his identification of the Lesser Sandhill Crane. So how can scientists and researchers in the fields of archaeology and natural history be so confident in their identifications?

  1. Provenience, provenience, provenience! - Being sure of where the faunal remains were discovered will limit the possibilities of identification. You don't need to worry about finding the bones of a koala in an Ohio cornfield!
  2. Morphology - All bones are not made alike. It's morphology, or size, shape, and even interior and exterior texture, can provide major indicators in identifying the animal as a mammal, fish, bird, reptile, or amphibian. From there, the overall size of the animal can be estimated to small, medium, or large.
  3. Compare & Contrast - Research labs - and even our own collections! - collect faunal remains of known species, sex, and age to compare unidentified bones. So the unknown bone of a small reptile can be compared to the bones of known reptiles for certain species identification. Check out this video on how Dave uses dermestid beetles to deflesh animal remains for comparative use.
  4. Textbooks - In lieu of a comparative collection, animal bone identification manuals are the next best thing!

Given experience in looking at bones, like Dr. Wetmore, Goslin, and Dave, a professional can make quick work of identifying animal bones!
