Definition and comments for the data column

@Species: Scientific names for extant and fossil species
@Locality (detail): Detailed information on the fossil locality using the latest administrative partitions and names.
@Lat./Long.: World Geodetic System 1984 (WGS84).
@Formation name: Based on current usage with that used in the original report in parenthesis.
@Geologic age: The latest chronostratigraphic chart provided by the International Commission on Stratigraphy (Cohen et al., 2013; updated).
@Age code: M0, Miocene; M1, early Miocene; M2, middle Miocene; M2-3, middle–late Miocene; M3, late Miocene; M3-PL, late Miocene–Pliocene; M-PL, Miocene–Pleistocene; M-PT, Miocene–Pleistocene; PL0, Pliocene; PL1, early Pliocene; PL1-2, early-late Pliocene; PL2, late Pliocene; PL2-, late Pliocene or later; PL-PT1, Pliocene–early Pleistocene; PL-PT2, Pliocene–middle Pleistocene; PL-PT3, Pliocene–late Pleistocene; PT0, Pleistocene; PT1, early Pleistocene; PT1-2, early–middle Pleistocene; PT2, middle Pleistocene; PT2-3, middle–late Pleistocene; PT3, late Pleistocene; PT-H, Pleistocene–Holocene; H, Holocene; R, Recent; NC, Not certain.
@Absolute age (Numerical age): The age of the formation (or layer) are sometimes determined independently by using absolute age dating methods. They are shown in parentheses. Abbreviation: 14C, radiocarbon dating; K-Ar, Potassium-Argon method; F.T., Fission-track dating.
@Comment for age: Original works for the age of the formation or stratigraphic position of tephra, for example, were shown in this field.
