Because of its many wetlands, which were haunted by Pleistocene animals during waning years of the Wisconsin glaciation, Orange County, southeastern New York State is a “classic” locality of North American palaeontology. The Peale mastodons were unearthed there in the late 18th century, and these remains, more than any other, awakened natural historians and the American public to the idea of animal and human evolution (Morrison 2001). Since 1780 at least 37 mastodons are reputed to have been discovered within Orange County (Devine n.d.), but in fact as many as 65 sets of remains are known for the county (Gary Keeton, personal communication). The ASAA Mastodon is 66th on this long list. It is, however, unique for being the only proboscidean skeleton among them having a strong association with ancient human beings.
Bones came to light during 2013 on the farm of Felix Gonzales along Bowser Road, north of Middletown, New York during digging of a drainage ditch on the edge of a former pond. This un-named, peat-filled pond has been cultivated since the early 20th century, and its rich muck yields bountiful crops of truck produce when the water table is not too high for cultivation.
Mr. Gonzales (See Figure A) had the presence of mind not to allow any ransacking of the skeleton, and he carefully collected all bone fragments that appeared upon the spoil piles. Curators from the New York State Museum in Albany were guided to the findspot by local palaeontologist, Gary Keeton, shortly after the discovery was made, and they helped in the search for bone fragments. However, no agreement for future scientific explorations by the Museum could be reached. It became a question of money; customarily the Museum does not purchase specimens destined for its cabinets.
A year later Mr. Gonzales offered to the highest bidder the mastodon bones he had recovered — a mandible (See Figure B), a fragmented tusk, a loose tooth, and other pieces filling two 30-gallon barrels — via Louis J. Dianni Auctions, Hopewell Junction, NY. Their August 10, 2014, sale, which was held at Garrison Landing, NY, on the Hudson River directly opposite the United States Military Academy at West Point, was well attended. On-line bids as well as offers over the telephone were accepted. The successful bidders were ASAA Members, Dennis J. Vesper (KY) and Steve Vaughn (FL). The winning bid totaled $24,000 including New York State sales tax and auctioneer’s fees; with the bones was the right to excavate remnants of the mastodon skeleton at the Gonzales Farm.

Our trip to the farm to pick up the barrels of mastodon bones that had been auctioned took place on August 19, 2014. The writer was accompanied by ASAA Members, Bud Driver (MA) and Greg Lott (MA). We cleared a tall growth of reed and nettles covering spoil piles and margins of a water-filled drainage ditch; Felix Gonzales directed our labor and assisted us. After clearance, a reference grid for future excavations was established. We then spent two hours sieving spoil using a 1/4-inch (6 mm) mesh (See Figure C). Our labor was handsomely rewarded with 176 bone and tusk fragments — mostly of small size but some as large as my hand (See Figure E).
Although the bone appeared to be in generally good condition, its fragmentation was a mystery. My suspicions were aroused that it was the result of ancient human interference — a condition reminding me of deer limb bones from prehistoric Indian sites that had been chopped into small sections for boiling and extraction of collagen (“bone grease”). It seemed that we might be dealing with an archaeological site and not just a palaeontological one.
This surmise was confirmed when a fragment of tusk ivory with two clear chop-marks was captured upon our sieve. The chopped edge must have been sharp when fresh; however, it had been dulled by use. The entire surface appeared to be polished by prolonged handling (See Figure 1A). In the parlance of stone tool typologists, this artifact would be called a “backed flake knife.” It was an exciting find, and as I considered the implications during the long return drive from Orange County to my home in North Andover, Massachusetts time passed quickly.
On September 8, 2014, Dennis Vesper (See Figure D), four other ASAA Members (Richard Sojka, Carl Kowalski, Denis Timko, Wendy Zebehazy) and I convened at the Bowser Road site and began to excavate. During later stages of fieldwork we would be joined by: Del Beck, Wayne Cankrow, O. Kirk Spurr, Nick and Cindy Miller, John Phillips, Bud Driver, Dave Graci, Andy Jaeger, Jonathan Wiener, Eric and Greg Lott and grandson Bryce, Alexandra Waugh, Joseph Hewitt, the Vaughn family (Steve, Chuck, Louisa) from Florida and Georgia, Glenn Kreisburg, Harriettt and Jerry Botdorf, and for one day by a team of volunteers from the New York State Archaeological Association (Margaret Staudter, Theodore Komosa, Gretchen Bock, Polly Midgeley, Pat Wilson). We were entertained and educated about Orange County palaeontology by Gary Keeton, who visited daily. His son, archaeologist Glenn, also assisted us on a weekend away from work at the American Museum of Natural History — showing great enthusiasm by wading along the drainage ditch and combing ooze for fragments of bone and tusk ivory that had fallen into it.

The first order of business was to glean the spoil piles that lay along the ditch for ivory and bone fragments and possible cultural materials. A 1/4-inch mesh was used exclusively, and sieving was in the hands of highly experienced individuals who thoroughly inspected every load of earth. While this recovery operation was underway, units of excavation were set out to either side of the ditch. A steel probe penetrating the peat had revealed several “targets” lying only 40-45 cm below surface; all these objects later proved to be mastodon bones and teeth/tusk. Meter squares were adopted as units of excavation, and spits of varied thickness were removed from units and sieved until the top of the calcareous marl was reached. There, at the contact with the overlying peat, most of the surviving mastodon skeleton was encountered.
It was immediately obvious that many bones still lying in original anatomical order had sustained damage and were fragmented. This destruction, it seemed likely, had resulted from frost, penetration by roots (See Figure F), and passing of heavy machinery. In addition, plowshares may have been responsible for some shearing and mixing. My working hypothesis that fragmentation was a result of processing and cooking by Palaeo-Americans had to be dismissed.
The first units to be explored, Units A and B, were among the most productive of the entire site. Unit B contained the solid ivory of nearly an entire tusk, which is shown partially exposed in Figures G and J. The ivory rimming the pulp cavity (estimated weight = 10-15 kg) of this tusk, however, appeared to be missing.
Among hundreds of small fragments of mastodon skull, the nearly intact tusk, and mastodon teeth that were recovered from Unit B was a trove of Palaeo-American artifacts fashioned of ivory (See Figure 1B-D and Figure 2 — seven of the fifteen objects shown in this Figure). An ivory adze and denticulate rabot are especially noteworthy. Both tools were exhausted and may have been curated because of the exceptional raw material from which they had been made. They represent an aspect of Palaeo-American technology that is seldom observed within the archaeological record of northeastern North America.

With so many man-made objects on record for Unit B, one wonders if nearly all the ivory, bone (See Figure 3), and stone artifacts that we salvaged from ditch spoil heaps were derived from that unit?
A few ancient artifacts, in addition to small amounts of mastodon bone and ivory, lay within the peat of the plow zone and in bizarre association with agricultural plastic (See Figure H), lumps of coal, furnace clinker, 20th century bottle glass, flowerpot fragments, and nondescript items of recent vintage. The full inventory of artifacts — ancient and modern — that was retrieved from the Bowser Road site through October, 2014, is given in Table 1.
Butchering Marks Upon the Skeleton
Separate from bones showing polish, use-marks and flake scars (See Figure 4), is the remarkable series of axe chop-marks and knife cuts on bones of the ASAA Mastodon. These vestiges of human industry are in excellent condition because of contact with calcareous marl; as a result, there was hardly any need to apply preservatives to them.
Although the archaeological literature about Palaeo-Americans and proboscideans is rich in evidence of butchering and dis-articulation (See for example, Fisher 1984; Shipman et al. 1984; Joyce 2006), the marks upon bone that have been described are hardly as robust as cuts that were made to the ASAA Mastodon. Obviously, a massive, sharp stone celt (see Gramly 1993: 46 for an example) was employed. It cut through centimeters of dense bone and caused gross damage. An axe may have been needed because dis-articulation took place during winter when the mastodon carcass was frozen.

By comparison, evidence for knife use at the Bowser Road site is slight (See Figure 5) and appears to have been confined to the skull.
Three parts of the mastodon skeleton show determined chopping — 1) the neck behind the skull, 2) the knee of the right hind leg, and 3) the right hind foot. Entering at the throat, the atlas and axis were chopped apart, and then the atlas was broken by repeated blows (See Figure 6). The Palaeo-American butcher may have wanted to loosen the head and then to turn it, thereby improving access to tusk ivory. Likewise, the knee of the right hind leg may have been cut up (See Figure 7) in order to free the tibia and femur. Their great lengths of dense bone may have been needed for tool-making. Parenthetically, it should be noted that neither of these bones — except for the severely damaged knee — survived at the Bowser Road site. By shearing off the outside of the right hind foot and passing through the astragalus downward to the calcaneus (See Figures 8-10), connecting tendons may have been severed. Disassembly of the hind leg, therefore, would have been easier. The excellent preservation of foot bones in contact with calcareous marl (See Figure I) facilitated recognition of butchering marks at the extremities. Likewise, we could be sure about the absence of cut-marks.
Animal Scavengers
There is remarkably little evidence of animal gnawing on the ASAA Mastodon, suggesting that the carcass had been exposed only briefly before it was visited by Palaeo-Americans. Also, the butchered mastodon may have sunk beneath the surface of the pond and remained out of reach shortly after Palaeo-Americans quitted it. Possible gnaw marks are present upon two ribs and the proximal end of the left tibia. On the tibia a broad groove (See Figure 11) may have been caused when a carnivore’s tooth slid across, but was unable to penetrate, this large bone.
The Antiquity of the Remains and Their Environmental Context
A piece of ivory of the nearly intact tusk within grid unit B was collected from the face of a break. This break lay deep within clean, gray clay (See Figure K for a section with exposed clay) — 40 cm beneath the interface of peat and marl. Therefore, contamination by modern humates seems unlikely. A portion of this ivory sample was submitted to Beta Analytic Laboratory for radiocarbon dating. Their result (Beta-391565), when corrected, is 10,950 +/- 40 RCYBP or 12,780 calendar years before present. Such an age is in basic agreement with many other North American sites having butchered proboscideans (for example, Hannus 1989) and indicates that Bowser Road site is perhaps a Clovis manifestation. The nearest well-dated Clovis site is Shawnee-Minisink along the Delaware River, northeastern Pennsylvania. It furnished several radiocarbon dates — including one of identical age to Bowser Road (Gingerich 2013: 219). The shallowly concave Clovis points of Shawnee-Minisink are reminiscent of specimens reported by Funk et al. from the Zappavigna site, approximately 75 km to the northeast in Orange County, New York (2003). Zappavigna and Bowser Road, it is worth noting, are separated by only 10-15 km of easily negotiated terrain.

A few palaeo-botanical specimens (spruce cones and a small fragment of wood) came to light during the exploration of the ASAA Mastodon; however, these remains are too sketchy for meaningful speculations about ancient environment during the Clovis visitation. Fortunately, coring for a study of ancient pollen was performed on the heels of the September, 2014, excavation; results of analysis are eagerly awaited.
In Sum
Proboscidean skeletons with clear-cut, obvious human association constitute a rare class of archaeological site world-wide (Gaudzinski et al. 2004). Single-carcass sites usually prove to be bull elephants (Ibid.), and the ASAA Mastodon, which is thought to be an aged bull (45-50 years old; Richard Laub, personal communication) is no exception.
Although the highly generalized stone artifacts (hammerstones, anvilstone, backed knife/ chopper, flakes, flake used as a scraper) and bone tools (beamers) from the Bowser Road site offer few insights about Clovis behavior, the ivory artifacts open a “window,” however slightly, to fresh interpretations. The adze, denticulate scraper, and backed flake knife have counterparts among Clovis flaked stone tools; however, until studies of their working edges are performed, we refrain from asserting that similarly-shaped ivory and stone tools had identical uses. The abraded or polished ivory “blanks” from Bowser Road (Figure 2) offer greater promise for expanding our understanding of Clovis technology. Objects of specific size and weight may have been intended for making buttons, toggles, and perhaps even non-utilitarian sculptures. Building analogies with discoveries at the Sloth Hole Clovis ivory workshop, Florida (Hemmings: 2004 174-177 ) and the Hiscock site, New York state (Laub 1995: 27-28) seem to be a route to follow.
Study of the ASAA Mastodon, its environment of deposition, and the nature of the Clovis artifact assemblage recovered among the bones has barely begun. This rare archaeological occurrence stands to yield insights far beyond the unassuming appearance and small size of the Bowser Road site.
