The Category-Modifier system: a hierarchical classification scheme for vertebrate tooth marks - supplementary tables

Preserved records of tooth-bone interactions, known as tooth marks, can yield a wealth of information regarding organismal behavior and ecology. For this reason, workers in a wide range of disciplines, but particularly paleontology, have inspected and interpreted these features for decades. Although previous studies have gleaned invaluable insights, they have also described tooth marks using terminological frameworks that have been incompletely defined, have incorporated behavioral hypotheses in definitions, and/or have been inconsistently applied. To address these problems, we introduce the Category-Modifier (CM) system, the first system to both sort tooth marks into clearly defined main categories and use descriptive modifiers to characterize their appearance more precisely. The CM system is designed to apply to a wide range of vertebrates, to enable comparisons across disciplines and studies, and to help researchers keep their investigations into behavioral hypotheses free of circula..., Measurements of tooth marks for UALVP 57561 provided in supplementary tables 2 and 3 were taken from a silicone peel (UALVP 57561.01) using a ruler. 
Measurements and modifiers of all tooth marks from previous studies provided in supplementary tables 4 and 5 were taken from published figures using the software ImageJ with the exception of DEN2-25. Measurements for tooth marks on DEN2-25 (specimen used in D'Amore and Blumenschine 2009, 2012) were obtained from a raw spreadhseet of measurements provided to TWH by D. D'Amore. Modifiers for tooth marks on DEN2-25 (specimen used in D'Amore and Blumenschine 2009, 2012) were obtained by direct examination of the tooth marked element which was sent to TWH by D. D'Amore. , , # Supplementary tables 1-5

Supplementary tables containing specimen information and raw measurements for the tooth marks described in the main text.

## Description of the data and file structure

Supplementary table 1 contains information on the taxonomic identity, type of element and surface preserving the tooth marks shown in figures, tables and supplementary tables.

Supplementary tables 2 and 3 contains measurements and modifiers for the specimen used in the worked example (Figure 5) as outlined by the Category-Modifier system.

Supplementary tables 4 and 5 contains measurements and modifiers for select examples from the literature shown in Figure 6 as outlined by the Category-Modifier system.

被保存下来的齿-骨相互作用记录，即齿痕（tooth marks），能够提供大量关于生物体行为与生态学的信息。正因如此，数十年来，众多学科的研究者——尤其是古生物学领域——都对这类特征开展了观察与解读工作。尽管既往研究已获得了诸多宝贵的认知，但相关齿痕描述所采用的术语框架往往存在定义不完整、将行为假说纳入定义范畴、以及/或应用标准不一致等问题。为解决上述问题，本研究提出了类别-修饰系统（Category-Modifier, CM）——这是首个既能将齿痕划分为明确定义的主类别，又能通过描述性修饰语更精准地刻画其外观特征的分类体系。本CM系统旨在适用于广泛的脊椎动物类群，支持跨学科、跨研究的对比分析，并助力研究者在行为假说相关研究中避免……（原文此处截断）。

补充表2与补充表3中收录的UALVP 57561标本的齿痕测量数据，均通过直尺对该标本的硅树脂翻模（UALVP 57561.01）进行测量获得。

补充表4与补充表5中收录的既往研究中所有齿痕的测量数据与修饰语信息，除DEN2-25外，均通过ImageJ软件对已发表的图表进行测量获取。

DEN2-25标本（即D'Amore与Blumenschine 2009、2012年研究中使用的标本）的齿痕测量数据，来源于D. D'Amore提供给TWH的原始测量电子表格。

DEN2-25标本的齿痕修饰语信息，则通过直接观察该带齿痕的标本获得——该标本由D. D'Amore寄送给TWH。
