By the 19th century, Archimel Oldham was running a ranch, and cattle (and to a lesser extent sheep) were a major part of the fauna found at the site of Blackwater Village in the late 19th century.
In historical periods, Tohono and Archimel Oldham's brand cattle and brand images appear in rock art (Bostwick and Crocker with reference to Bostwick and Crocker 2016), indicating the integration of animals into other cultural dimensions.
Cows and sheep
Semi-wild cattle ranching was the main economic activity of the Tohono-Oldham people, and pastures were often shared—a practice dating back to missionary times—until the Great Depression of the 2030s, when the U.S. government ordered the establishment of grazing areas, severely undermining traditional grazing and water rights. Beef, in particular, has become the core of local and indigenous dishes in the form of jerky, stews, etc. Chilean Colorado, and beef tallow.
Today, beef is considered part of home cooking by members of the Tohono Oldham tribe (cf. Fazzino 2008) and pastures remain the main economic activity on the reserve.
The animal remains in this study come from historical sites associated with Mission Guevavi on land managed by the Tumacácori National Historical Park (feature 26).
The collections are currently housed at the National Park Service's Western Archaeological Conservation Center in Tucson, Arizona.
The reported samples were screened through a 6.35 mm screen.
The zoarchaeology analysis followed Reitz and Wing (cf. Reitz and Wing 2008) and was originally published in Mathwich (cf. Mathwich 2016).
Using standard zoological methods (Reitz and Wing), the authors identified vertebrate remains from the Mission Gwavi Field School with reference to Reitz and Wing, 2008).
As part of the analysis, various observations, such as elemental and taxonomic identification, were collected, which could be replicated by later researchers (Reitz and Wing refer to Reitz and Wing 2008).
Observed sex, age of death, and modified indicators were recorded.
The age range comes from observations of epiphyseal fusion and tooth eruption above the gum line.
The presence of wear and tear is significant in terms of age, as it means that the tooth erupts completely.
In this article, "goat" is the term used to describe the remains of animals that may be domestic sheep or goats.
However, during the Spanish colonial period, sheep were the most common small domestic cattle (Kessel cf. Kessel 1970; Police officer reference officer 1987), goats are also available, but in much smaller numbers.
In 1768 church inventories in the area recorded 10,069 sheep and 251 goats, or 2.4% of all small livestock.1767).
The minimum number of individuals (MNI) is reported in this study, which is derived from the minimum number of elements (MNE).
MNE is calculated by considering element parts, edges, size, and fusion; Teeth are excluded from MNE.
Sometimes, the lower classification category is smaller than the MNI of the corresponding higher classification hierarchy.
MNIs for lower classification categories are reported in parentheses but are not included in subsequent calculations.
MNI increases with the increase in smaller, discrete origins used for analysis, leading to problems with aggregation and accuracy (Dominguez-Rodrigo Dominguez-Rodrigo 2012; Grayson references Grayson 1978; Lehmann refers to Lehmann 2019), but MNI is valuable when examining the degree of fragmentation.
Debris can indicate disposal patterns, bone marrow extraction, and lipid extraction (Outram Reference Overrange 2001). The Guevavi assemblage and the contemporary Pimería Alta assemblage reflect the large number of fragmentation associated with oil refining.
For these reasons, MNI is reported, but based on the allometric growth relationship reported by Reitz and Wing, it is associated with the number of identified specimens (NISP) and biomass (see Reitz and Wing 2008) to balance the overestimation of smaller taxa by MNI.
Isotope determination of carbonates
Isotope determination of tooth enamel carbonate was analyzed to obtain information about the animal's diet.
Tooth enamel carbon is used to detect the dietary proportion of plants during tooth development.
Oxygen isotopes from tooth carbonates help researchers understand the type of water the animals consume.
Other isotopes, such as nitrogen and strontium, are valuable in explaining animal management practices and the movement of animal products.
Carbon and oxygen come from tooth enamel bioapatite, not collagen.
Carbon and oxygen were specifically chosen for their ability to illuminate plant communities and environmental water sources. These methods were originally summarized here in Mathwich and his colleagues (cf. Mathwich, Pavo-zuckerman, and Ruff 2019).
Drill 1-3 mg of enamel samples from teeth to maintain overall physical integrity and recognizability.
Sampling the teeth using small drills produces a shallow, vertical grooved bulk sample in the outer enamel of the crown, which reflects the average consumption during tooth development.
Bovine molars crowns take about a year to form (Hilson cf. Hilsen, 2005).
The composition of bioapatite in oxygen and carbon isotope 3 tooth enamel was extracted from carbon monoxide and calculated using offsets of Kohn and Cerling (refer to Kohn and Cerling 2002:465).
The powder sample was pretreated to separate the structural carbonate-apatite and remove organic matter and secondary carbonate.
Add 0.1 μ dilute solution of acetic acid to the sample, soak overnight, and remove with a pipette.
Although no longer recommended (Pellegrini and Snoeck refer to Pellegrini and Snoeck 2016), this aggressive pretreatment is standard practice in environmental isotope laboratories when performing analyses in 2015.
The sample is then rinsed with ultrapure water and allowed to dry overnight.
δ18o and δ13 measure the c of carbonate using an automated carbonate preparation device (KIEL III) connected to a gas ratiometric mass spectrometer (Finnegan MAT 252).
The powder sample reacts with dehydrated phosphoric acid under a vacuum at 70 °C.
Isotope ratio measurements are calibrated based on repeated measurements of NBS-19 and NBS-18 with an δ accuracy of 0.1‰18o and δ13C (1σ) of 0.08‰.
Grading of bovids
The classification of bovines reported by Passey et al. (refer to Percy, Robinson, Elif, Serin, Sponheimer, Dennis Dilling, Rodel, & Elleringer 2005) to calculate δ13C The enamel diet is α enamel diet = 1.0146.Note that the δ13c value has been corrected for modern fossil fuel consumption (1.5‰; Friedrich et al.).
The ratio of rare samples to R standard reference is 13 points 12 and, as samples or standards, they are relative to the VPDB standard (Kendall and McDonnell refer to Kendall and McDonald 1998). The terminal element of C3 used to calculate the percentage of C 4 in the animal's diet is derived from Kohn (cf. Kohn 2010), and the modern C412.5‰ VPDB terminal element is from Cerling et al. (cf. Serin, Harris, & Percy 2003).
The historical material presented here was translated by Kessel from the original Spanish into English (cf. Kessel 1970) and the author consulted the Office of Human History Research at the Arizona State Museum in Tucson.
The documents, written by Jesuit priests funded by the Spanish colonial government, represent the mission's count of herd size.
These documents, which represent the views of the missionaries, are concerned with the goods and possessions of the mission, and they are not meant to be a demonstration of livestock management.
The author's use of them for livestock management is her own interpretation of the literature.
The results of the above analysis were used to assess the presence of semi-wild management of cattle and to compare it with sheep management of the Guevavi Mission.
Several patterns related to interspecies differences emerged in these results.
First, the isotopic ratios of tooth enamel from cattle and sheep showed differences in water and grazing sources.
Second, sheep animals die at an age of less than three years, while cattle appear to die at an age greater than three years.
Third, historical sources show different conceptual classifications of domesticated species, but provide sparse information about the actual management of animals.
Stable isotope analysis
A total of 13 samples were selected for sampling from 180 stocked whole teeth that were part of a larger study consisting of adult molars (Mathwich et al.).
The Mission is unique in that it has a large sample size of teeth, and it offers the most personalized samples.
With that note, the sample is small.
Because the sample came from a larger midden feature, the sample for this item was higher than the reported MNIs, which did not include teeth.
Goats have higher MNI, but fewer adult tooth samples because baby teeth appear more frequently in collections.
Samples are selected based on their completeness, tooth location, and age.
%C4 plants in the cattle diet accounted for 75% to 104% of the animal diet, δ18O bioapatite ranged from 4.36‰ to 0.44‰±0.10 VPDB (Figure 2).%The plants in the C4 goat's diet ranged from 21% to 52%, and δ18O bioapatite ranged from 1.34‰ ~ 3.31‰±0.10 VPDB.
Mathwich and colleagues (cf. Mathwich, Pavo-zuckerman, and Ruff 2019), as well as Grimsted and Pavao-Zuckerman (cf. Grimsted and Pava-Zuckerman 2016), found that oxygen levels in both goats and cattle were very high compared to average rainfall.
Independent sampling of modern water sources and leaf enrichment found that the most likely explanation is evaporation, which results from the enrichment of water storage.
In Guevavi, goats seem to have more water than cattle.
Guevavi's data are consistent with contemporary Pimería Alta sites, suggesting that these ratios indicate a wider range of dietary differences between cattle and goats (Grimstead and Pavao-Zuckerman with reference to Grimstead and Pava-Zuckerman, 2016; Mathwich et al.
Cf. Mathwich, Pavo-zuckerman, & Ruff, 2019). Cattle eat mainly C4 plants, which reflects a reliance on semi-desert grasslands—grasses in southern Arizona—especially granma grass (Bock and Bock Reference Block and Block 1986). The high proportion of plants in C4 cattle feed is compatible with CAM plants such as edible cacti.
However, studies of pasture behavior have shown that grass is their preferred grazing food (Hanselka and Pascal refer to Hanselka and Pascal 1990).
δ scatter plot Figure 13C prescribes diet and percentage C 4 In the diet of animals, δ13C bioapatite and δ18O bioapatite were extracted by location and taxa from a large sample of cattle and goat teeth.
In cattle, epiphyseal fusion age is roughly in three main groups at the following stages of an animal's life: early (7-20 months), mid-stage (24-36 months), and late (42-48 months; Barone reference Barronne 1976; Silver Reference Silver, Broadwell and Higgs 1969). These broad categories cover a range of epiphyseal events that vary by nutrition, hormones, health, and geographic location.
Modern epiphyseal fusion rates (Moran and O'Connor cf. Moran and O'Connor 1994; Popkin et al.
Age estimation for domestication of ungulates
The total MNI of cattle was at least 5 individuals, and at least 8 goats were identified (Table 2).Of the cattle elements, 63% (17) of late fusion elements (over 36 months) were fused and 85% (17) of intermediate fusion elements (more than 24 months) were fused.
At least one younger individual is represented, but most individuals are adults aged three to nine years (Table 3).In goats, 43% (25) of early fusion elements (3-16 months) are fused, but 79% (45) of intermediate and late fusion elements (7-60 months) are not fused.
Individuals ranged in age from three to four years old, with one over four years old.
A total of 7 teeth were identified as mandibles in situ, but the sample size was not large enough to observe tooth wear at the population level.
Bovine mandibles with orthotopic teeth have well-developed M3 teeth and show considerable wear, estimating age over 36 months (Hilson cf. Hilson 2005).The estimated age of goats erupting from the teeth of the four left mandibles varies from one to two years of age at the time of death (Moran and O'Connor reference Moran and O'Connor 1994).Once erupted, M3 becomes a less reliable age indicator due to the absence of population-level wear patterns, but in general, The Gwavi cattle were older than 3 years old at the time of their death.
