Caddo Ceramics From Mound Deposits At The Shelby Mound Site (41cp71) On Greasy Creek, Camp County, Texas, Timothy K. Perttula
Caddo Ceramics From Mound Deposits At The Shelby Mound Site (41cp71) On Greasy Creek, Camp County, Texas, Timothy K. Perttula
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
Archaeological evidence from 15th to 17th century (dating from ca. A.D. 1430-1680) Caddo sites that have been investigated in the Big Cypress Creek and Sabine River basins of northeastern Texas indicate that many of the components have been identified as belonging to the Titus phase. They represent permanent, year-round, settlements of horticultural or agricultural peoples with distinctive cultural practices and material culture. The 15th to 17th century archaeological record in these two basins “refers to a number of distinctive socio-cultural groups, not a single Caddo group; these groups or communities were surely related and/or affiliated by kinship, marriage, and social …

New Radiocarbon Dates From East Texas Caddo Sites, Timothy K. Perttula, Robert Z. Selden Jr.
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
In this article, we report the results of AMS dating of organic remains from ancestral East Texas Caddo sites in Gregg and Harrison counties. These sites are the Wade site (GC-38), a Middle Caddo period habitation in the mid-Sabine River basin, as well as from vessels (in the Gregg County Historical Museum) placed in Caddo burials at the Susie Slade (41HS13), Hyte, Eli Fields, J. O. and Henry Brown (41HS261), and the Patton (41HS825) sites in the Big Cypress and mid-Sabine River basins, and a vessel from an unknown site in the Big Cypress Creek basin.
The Distribution Of Negative Painted Pottery In The Caddo Area, Timothy K. Perttula
The Distribution Of Negative Painted Pottery In The Caddo Area, Timothy K. Perttula
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
Negative painted pottery (NPP) is one of the most distinctive kinds of pottery made by Mississippian peoples during the Middle Mississippian period (ca. A.D. 1200-1500) in eastern North America. This pottery is decorated with a “resist painting technique, which creates a lighter-colored design outlined by a black pigment” over an underlying slip/wash.
Principal production areas for NPP include the lower Ohio River valley, the Nashville Basin, and the Bootheel of southeast Missouri, and there are four main types: Kincaid Negative Painted, Nashville Negative Painted, Sikeston Negative Painted, and Angel Negative Painted. This NPP has been found in several sites in …

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
Following up on the discovery of 10 passenger pigeon elements from one bird in a Caddo burial feature (Burial 52) at the Mitchell site (41BW4) on the Red River in Bowie County, we have documented the distribution of passenger pigeon on Caddo sites in the Trans-Mississippi South. To date, we have identified 10 Caddo sites dating between ca. A.D. 1160-1710 with passenger pigeon bones, along with two Woodland period sites (generally predating ca. A.D. 800-900) in the region. These sites range as far east as the Saline River basin in Southwest Arkansas, as far west as the George C. Davis …
Caddo Ceramic Vessels From The Mcspadden Site, Robert Z. Selden Jr.
Caddo Ceramic Vessels From The Mcspadden Site, Robert Z. Selden Jr.
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
The McSpadden site (unrecorded and with no site trinomial) is located on the outskirts of Frankston, Texas, in Anderson County, where three Caddo vessels were recovered during the construction of a local roadway during the early 1950s. These vessels are currently curated in a private collection in College Station, Texas. All come from the same small area, and based upon their stylistic character and vessel forms, appear to date to the Late Caddo period (ca. A.D. 1400-1650) in this part of East Texas.

Ancestral Caddo Ceramics In East Texas, Timothy K. Perttula, Robert Z. Selden Jr.
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
The most distinctive material culture item of the ancestral Caddo groups that lived in East Texas from ca. A.D. 900 to the 1830s were the ceramics they manufactured primarily for cooking, storage, and serving needs. The decorative styles and vessels forms of the ceramics found at sites in the region hint at the variety, temporal span, and geographic extent of a number of ancestral Caddo groups that lived in this area. The diversity in decoration and shape of Caddo ceramics is considerable, both in the utility ware jars and bowls, as well as in the fine ware bottles, carinated bowls, …
The Classification Of Late Caddo Period Utility Ware Jars From Sites In The Big Cypress Creek Basin Of East Texas, Timothy K. Perttula
The Classification Of Late Caddo Period Utility Ware Jars From Sites In The Big Cypress Creek Basin Of East Texas, Timothy K. Perttula
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
Much of the decorated utility wares found in Titus phase mortuary vessel assemblages in the Big Cypress Creek basin of East Texas has been typologically identified over the years as "Miscellaneous Fulton Aspect [Late Caddo] Utility Pottery," which has hindered the full appreciation of the stylistic, temporal, and stylistic diversity that exists among theses sites in the region, or to the extra-local region. The diversity apparent in the decorated utility wares from Titus phase sites has a considerable potential to she light on the existence and spatial distribution of communities of Caddo potters sharing or not sharing utility ware decorative …
Predictive Modeling Of A Caddo Structure In The Ouachita Mountains, Montgomery Counts, Arkansas, Vanessa N. Hanvey
Predictive Modeling Of A Caddo Structure In The Ouachita Mountains, Montgomery Counts, Arkansas, Vanessa N. Hanvey
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
During the Arkansas Archaeological Survey/Society Training Program in June, 2014, an arc of postmolds from a Caddo structure was uncovered at site 3MN298. The site is located in Montgomery County, Arkansas, within the Ouachita National Forest, on a bend of the Ouachita River. After reviewing the literature on Caddo architecture, an attempt was made to predict the size and shape of the building as well as the location of any associated features. In September, 2013, a small field crew effectively ground-truthed the model. This article explores the process of creating and using a predictive model to guide archaeological excavations of …
Burned Rock Mounds In North-Central And Northeastern Oklahoma, Robert L. Brooks
Burned Rock Mounds In North-Central And Northeastern Oklahoma, Robert L. Brooks
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
Burned rock mounds haven been identified in Oklahoma since the early twentieth century. The Oklahoma River Basin Survey pioneered the study of these features of the cultural landscape in the 1960's- 1970's; however, little research has taken place since that time. This paper reports on the history of research pertaining to burned rock mound features, examines their distribution on the cultural landscape and their construction, analyzes the artifact content of the mounds, and presents some thoughts on the purpose of mound construction and use
Towards A Common Understanding: A Revision Of Fourche Maline Chronology In Oklahoma, Luther J. Leith
Towards A Common Understanding: A Revision Of Fourche Maline Chronology In Oklahoma, Luther J. Leith
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
Answering the question of what Fourche Maline is has long been hampered by lack of consensus on the terminology and chronology within the ancestral Caddoan area of the four corners area of southeast Oklahoma, southwest Arkansas, northeast Texas and northwest Louisiana. To address this problem an evolution of the Oklahoma concept of Fourche Maline is presented, and developing a new chronology based on seriation of temporally sensitive artifact categories is discussed. It is concluded that Fourche Maline is a solely Woodland period culture, with a chronology that makes identifying changes over time possible. This conclusion will facilitate the understanding of …
Looped And Perforated Elbow Pipes In Northeast Texas, Jesse Todd
Looped And Perforated Elbow Pipes In Northeast Texas, Jesse Todd
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
Todd presented a general chronology for the presence of aboriginal-manufactured clay elbow pipes in Northeast Texas Caddo sites. Most of the pipe types have an extensive range in time; however, this may be true for thong elbow pipes. This paper looks further at the time range for; and the variety, of thong pipes.
Jackson refers to elbow pipes that have a hole between the keel and the bowl as "thong pipes." A string appears to have been run through the holes. He refers to the two types of pipes as "handled" and "holed," but "I use the terms "looped" and …

This three volume set written and compiled by Dr. Jim Tiller of Sam Houston State University (Huntsville, Texas) represents a significant body of work concerning the history of East Texas-Northwest Louisiana between 1803-1842. His study area includes what is now Caddo Parish in Louisiana and Harrison and Panola counties in Texas. Tiller's interest in the history of the Caddo Indian in this area is also shown by a series of articles he has written about them in recent years.
Peyoteism And The Origins Of Caddo Religious Thought, Robert Cast
Peyoteism And The Origins Of Caddo Religious Thought, Robert Cast
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
The Caddo Indians practiced a vibrant peyote religion long before John Wilson (Moonhead) or Quanah Parker re-ignited the Native American Church. Moreover, research has show the importance of the peyote plant to the Caddo long before any European contact. The peyote religion at the time of the Spanish mission in Texas was full of songs and dances in honor of one known today as (Aah-hi-u kuu-i'-ha) or Father Above, translated to mean home where God lives. Although Swanton proposes that the Hasinai medicine men used peyote "at the beginning of the eighteenth century" (a reference to Friar Hidalgo's Spanish account) …

In an attempt to better comprehend the geochemical composition of ceramic sherds across the traditional Caddo landscape, the INAA results for 1192 sherds from 164 sires are employed within this discussion (not included in this sample are sherds from sites recovered in central Texas.) After assembling the dataset, two table were used - one with geochemical data, one with site data - to catalog the sample. The shell and bone-tempered sherds were noted, but the calcium correction was only applied to 4% (n=47) of samples known to be shell-tempered.
