The concept of projectile point series was first developed in California and the Great Basin in the 1950s and 1960s. In 1981, applying the Monitor Valley projectile point key, Thomas (1981) assigned chronological ranges to five projectile point series for the Great Basin, the Gatecliff Series, the Humboldt Series, the Elko Series, the Rosegate Series, and the Desert Series, which were based on the Berkeley projectile point naming conventions. Each of these series, which are still in use today, include different morphological point forms that—although sharing the same primary designator—do not share the same temporal spans or geographic distributions. Morphologically different projectile points do not share a priori temporal, geographic, or cultural associations simply by virtue of sharing a series label. The use of the series concept and chronology in projectile point analyses in the West should be discontinued and replaced with analyses of morphological forms, geographic distributions, and temporal spans of individual point types.

弹丸点系列的概念最早于 1950 年代和 1960 年代在加利福尼亚和大盆地发展起来。1981 年，应用 Monitor Valley 弹丸点键，Thomas （1981） 为大盆地的五个弹丸点系列分配了时间范围，即 Gatecliff 系列、Humboldt 系列、Elko 系列、Rosegate 系列和 Desert 系列，它们基于伯克利射弹点命名约定。这些系列中的每一个今天仍在使用，都包含不同的形态点形式，尽管它们具有相同的主要指示符，但并不具有相同的时间跨度或地理分布。形态上不同的弹丸点不会仅仅因为共享一个系列标签而共享先验的时间、地理或文化关联。在西方的弹丸点分析中，应停止使用系列概念和年代学，取而代之的是对单个点类型的形态形式、地理分布和时间跨度的分析。
