1. The mesiobuccal cusp of human upper molars.
2. A cusp arising from the protocone in the evolution of the molars; thought to be the first cusp to arise, rather than the protocone.
[para- + G. kōnos, cone]

Ectoloph is convex and has a paracone fold along the entire height of the tooth.
To determine cusp relief, we measured the depth of the valley between the paracone and metacone cusps as well as the anteroposterior length of each tooth using the computer software ImageJ 1.
The protocone and paracone are equivalent in size, and separated from the hypocone-metacone complex by a deep valley.
The paracone is on the anterior margin of the tooth and is larger than the metacone, which is on the posterior margin.
Using these criteria, four age groups were identified, which were suspected to represent annual cohorts characterized as follows: 1) young adults--slight to moderate wear on paracone and metacone of P4, M1, and M2, but protocone only slightly worn, P3 with virtually no (or only slight) wear; 2) adults--distinct wear on cones of P4 and all molars but individual cones clearly separated from each other except on M3 (wear had obliterated divisions between some cones and styles), P3 moderately worn; 3) adults--cones no longer distinct on molars, some cone integrity remains on P4, top occlusal surface of P3 nearly flattened; 4) old adults--P3 appearing as a flattened peg, P4-M3 heavily worn, cones distinct (if present) only on labial margin of teeth.
The paracone is almost equal to the metacone in antero-posterior length.
