Molar landmark and outline coordinates

These are the original point coordinates (in tps format) used in a geometric morphometric analysis of lower molar shape. For each genus, the first seven coordinates are cusp landmarks, the next 20 coordinates outline the talonid, and the final 20 coordinates outline the trigonid. (Note that the outline coordinates are not equally-spaced semilandmarks.) See Grossnickle & Newham (2016) for information concerning how these coordinates were analyzed.本数据集包含用于下颌臼齿形态几何形态计量分析的原始点坐标，格式为TPS（tps）。对于每个属而言，前7个坐标为牙尖标志点（cusp landmarks），后续20个坐标用于勾勒跟座（talonid）的轮廓，最后20个坐标则用于勾勒三角座（trigonid）的轮廓。（注：此处的轮廓坐标并非等间距半标志点（semilandmarks））有关本批坐标的具体分析方法，请参阅Grossnickle与Newham（2016）的相关研究。
