Geometric Morphometric Analyses Support Incorporating the Goshen Point Type into Plainview

Summary:Recent work has demonstrated that Goshen points overlap in time with another group of unfluted lanceolate points from the Plains, Plainview points. This has raised the question of whether the two types should be kept separate or consolidated into a single type. We sought to resolve this issue by applying geometric morphometric methods to a sample of points from well-documented Goshen and Plainview assemblages. We found that their shapes were statistically indistinguishable, which indicates that Goshen and Plainview points should be assigned to the same type. Because Plainview points were recognized before Goshen points, it is the latter type name that should be dropped. Sinking Goshen into Plainview allows us to move beyond taxonomic issues and toward understanding both the spatiotemporal variation that exists among Plainview assemblages and what it can tell us about the adaptations and social dynamics of Plainview groups. El trabajo reciente de citas ha demostrado que Goshen apunta se superponen en el tiempo con otro grupo de puntos lanceolados sin fluir de los puntos Plains, Plainview. Esto ha planteado la cuestión de si los dos tipos deben mantenerse separados o consolidados en un solo tipo. Buscamos resolver este problema mediante la aplicación de métodos morfométricos geométricos a una muestra de puntos de los bien documentados ensamblajes de Goshen y Plainview. Encontramos que sus formas fueron estadísticamente indistinguibles, y sugerimos que los puntos de Goshen y Plainview se asignen al mismo tipo. Debido a que los puntos de Plainview se reconocieron antes que los puntos de Goshen, es el último nombre de tipo el que debe abandonado. Sumergir a Goshen en Plainview nos permite ir más allá de los problemas taxonómicos y tratar de comprender la variación espaciotemporal que existe entre los conjuntos de Plainview y lo que puede decirnos acerca de las adaptaciones y la dinámica social de los grupos de Plainview.
