Valentin Calderón figura como um dos pioneiros da arqueologia no Nordeste do Brasil. Membro do Programa Nacional de Pesquisas Arqueológicas entre as décadas de 1960 e 70, foi responsável pelos levantamentos sistemáticos nos sítios arqueológicos do estado da Bahia e identificou a tradição cerâmica Aratu. Calderón foi também o idealizador do Museu de Arqueologia e Etnologia da Universidade Federal da Bahia (MAE/UFBA), que hoje salvaguarda sua coleção arqueológica e seu arquivo pessoal. Em uma parceria realizada com pesquisadores do Center for Regional Heritage Research da Stephen F. Austin University, Texas, EUA, os artefatos cerâmicos da coleção Valentin Calderón foram digitalizados através do uso de tecnologias 3D. No total, foram escaneados 27 objetos cerâmicos, dentre vasilhames e urnas funerárias. A iniciativa ofereceu subsídios para pensar a digitalização como forma de preservação, principalmente no que se refere à conservação e restauração, documentação e comunicação do acervo. Os modelos 3D resultantes do processo de digitalização permitem uma análise detalhada dos artefatos e obtenção de dados sem a manipulação direta, contribuindo de forma relevante para a preservação dos acervos. Os dados e modelos serão, em breve, disponibilizados para a pesquisa e também utilizados na nova exposição de longa duração do MAE/UFBA.
On November 15, 1999, the Center for Archaeological Research (CAR), The University of Texas at San Antonio, returned 122 curation boxes containing human remains of between 103 and 125 individuals to Monsignor Balthazar Janacek, Archdiocese Director, Old Spanish Missions. These remains had been obtained during two previous Witte Memorial Museum excavations at Mission San Juan Capistrano. Subsequently, CAR returned the majority of the burial goods associated with these human remains to Monsignor Janacek. CAR then entered into an agreement with the Archdiocese of San Antonio to locate and monitor the excavation of the two reburial areas that were to coincide with two previously excavated areas. The location and monitoring of the reburial areas began on November 22, 1999. The reburial of the human remains and associated artifacts occurred on November 27, 1999. Present at the reburial ceremony were representatives of the Archdiocese of San Antonio, the National Park Service, the American Indians of Texas at the Spanish Colonial Missions, a member of CAR, and member of the press and public.
NCPTT, the friends of NCPTT, and the National NAGPRA Program will partner to offer a four-day course on the statute, regulations, requirements, and compliance aspects of NAGPRA. The objective is to introduce participants to the purpose and requirements of NAGPRA. Classroom instruction will include discussions with NAGPRA representatives from Indian tribes who will share their responsibilities and experiences. The workshop will conclude with demonstrations of innovative technologies that can be used for documenting artifacts prior to repatriation as well as for current and future research.
I will be there to discuss the work that we are doing with the Caddo Nation of Oklahoma, and to illustrate how we are capturing, analyzing and curating 3D data associated with Caddo NAGPRA materials. Further details, including the option to register for this workshop, can be found on the NCPTT website (here).
In August 1994, the Center for Archaeological Research entered into a contract with the San Antonio Parks and Recreation Department to provide monitoring for the Trevino Street improvements immediately to the north of San Fernando Cathedral in downtown San Antonio. Previous investigations had shown that the stone-lined San Pedro acequia existed at the curb line on Main Avenue.
Monitoring was conducted as the street surface was removed and, as expected, the acequia was exposed. The location of the acequia was documented by photography and measured drawings. A plan map of the location was produced and archival research revealed the history of the channel at this location.
Personnel from Prewitt and Associates, Inc., conducted test excavations at 41HE257, a prehistoric site located in central Henderson County. This work was conducted for the Texas Department of Transportation (TxDOT), Environmental Affairs Division, since part of the site is within the right of way for the southern expansion of FM 317, the Athens Loop. The work was done under Texas Antiquities Permit No. 3070 and all materials collected and records generated are curated at the Texas Archeological Laboratory, The University of Texas at Austin. The excavations showed that the site is shallow and contains few lithics or ceramic artifacts, limited botanical remains, no faunal remains, and only one possible rock feature. One radiocarbon assay indicates the presence of an early Late Prehistoric component. However, that component could be mixed with earlier and later materials, and definition of discrete components is not possible. As such, the site has little capacity to yield important information and is considered ineligible for listing in the National Register of Historic Places or designation as a State Archeological Landmark.
Cultural resources management (CRM) reports represent a rapidly growing proportion of our knowledge associated with archaeological undertakings in the United States. Historically, these reports were printed in limited numbers and distributed to a few libraries and individuals, and few were distributed beyond the political boundaries of any given state. Libraries on the distribution list are reticent to allow patrons to check out these reports due to the fact that they have—and will only ever have—a single copy. Late in 2009, the Texas Historical Commission (THC) permitting guidelines for CRM reports were updated, requiring CRM contractors to submit a digital copy of a redacted (no site locations or photographs of human remains) report before their permits could be closed. These reports, the lion’s share of which were funded with public monies, were meant to be made publicly accessible and should be available.

Using the suite of tools available to us through bepress means that the Index of Texas Archaeology (ITA) is archived in Portico, and that our content is indexed by Google, Google Scholar, CrossRef, and Altmetric. Digital object identifiers (DOIs) are being assigned to each report using CrossRef, whereby both the report and the references that each report cites—those that have a DOI—are indexed (view ITA records on CrossRef here).
In addition to CrossRef, we are also working with bepress to integrate CrossMark, which will allow readers to ensure that they are citing the most up-to-date content. Any changes in the published version will be noted in the metadata, which can be accessed by clicking on the CrossMark logo. We are also working through the process of implementing the CrossRef API to include cited-by linking, where readers will be able to view those publications that cite each of the ITA reports. This manner of increased accessibility and distribution also helps to ensure that report authors, and those authors whose work is cited in the reports, receive full credit—and accessible metrics—for their efforts, similar to their colleagues in academia.

The excavations by Atkins at the Santa Maria Creek site (41CW104) described in the following report have succeeded in bringing together a myriad of information regarding aboriginal occupations in eastern Central Texas at the dawn of the Historic period. The analysis of the materials recovered from National Register of Historic Places testing and data recovery has demonstrated that even a site buried in sandy, bioturbated sediments can still significantly add to the archeological record. This becomes even more important for areas such as Caldwell County, Texas, which have witnessed few such investigations. The report utilized a wide array of analytical techniques to unravel the site, including extensive ethnohistorical research, artifact analysis, special studies, and experimental archeology.
While pursuing a study of 3D geometric morphometrics for ceramic burial vessels that often articulate with the Native American Graves Protection and Repatriation Act (NAGPRA) from the ancestral Caddo region, there have been no shortage of potentially meaningful observations, one of which–rotational asymmetry in coil-built vessels–is discussed in this publication. Using Geomagic Design X (reverse-engineering software) and Geomagic Control X (computer aided inspection software), metrics associated with rotational asymmetry were generated then analyzed.
Results indicate variable asymmetry among the different vessel shapes (i.e., bottles, jars, etc.), which may augment and strengthen studies and discussions of vessel form. Future directions include the incorporation of directional and–possibly–fluctuating asymmetry measures for the widest vessel profiles. Preliminary results point toward substantive analytical gains that can be used to augment more traditional ceramic analyses as well as geometric morphometric studies of ceramic vessel shape.
In addition to the analysis of rotational asymmetry, there is a brief discussion for analyses of (directional and fluctuating) asymmetry using geometric morphometrics. While the bulk of that discussion remains the topic of another paper, the citation network for asymmetry studies that use geometric morphometrics was included in this paper, and can be accessed by clicking on the image or the link below.

Many thanks to the Caddo Nation of Oklahoma for the requisite permissions needed to scan the vessels, and to the Anthropology and Archaeology Laboratory for access.
Archeologists from TRC Mariah Associates Inc. of Austin conducted mitigation excavations at the Lino site (41WB437) during a six-week period in April and May 1998 under contract with the Texas Department of Transportation, Environmental Affairs Division. The prehistoric archeological site was within the right-of-way of the planned expansion of Highway 83, south of Laredo. A single 196 m2 block measuring 7m north-south by 28 m east-west was investigated following requirements of a contract that stipulated a three-pronged approach to data recovery. First, a Gradall™ was employed to carefully strip 2 to 4 cm thick layers in eight 3m wide areas within the block. Balks measuring 80 cm wide by 120 cm tall were left standing between each 3 m wide Gradall™ -stripped area. The material discovered in situ during the Gradall™ stripping was plotted using a total data station. When clusters of cultural materials were encountered during the Gradall™ stripping, these were designated as features, and a series of manual excavations in 1 by 1 m units were dug around each feature. The matrix surrounding these features was screened and in situ data recorded with the total data station. Feature matrix was collected and floated in the laboratory. A total of 124 m2 were hand excavated around 24 recognized features discovered during Gradall™ stripping. Upon reaching the target depth of 120 cm below the surface, the Gradall™ stripping ceased, having mechanically removed 187 m3 of deposits.
