par·a·cone

(par'ă-kōn),
The mesiobuccal cusp of an upper molar tooth.
[para- + G. kōnos, cone]

par·a·cone

(par'ă-kōn)
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]

Remarks--The ectoloph of this tooth is strongly pigmented on the faces of the shearing blades below the postparacrista, premetacrista, and postmetacrista, but the pigment stops before reaching the base of the paracone and metacone.
Remarks--The P4s appear to have only light pigment on the tip of the paracone.
In general, the P4 of amphicyonids is laterally compressed and the protocone is nearly in line with the paracone and metacone as exhibited by SDSM 82105.
Manipulation of an external light source helped to manifest the microwear scars on the paracone of the second molar.
4 mm ocular reticle on the paracone of the second molar.
trees were estimated using current methodology (Huber's formula and local volume tables), modem techniques (the paracone method, the centroid method, importance sampling, control-variate sampling, singly and in combination) and Cascade Correlation Artificial Neural Network (CCANN) models.
1991) found that the paracone method was slightly better than centroid methods for predicting tree bole volumes.
The paracone and metacone are subequal in size with metacone positioned slightly toward the midline (linguad).
In the second case, the holes could have been made by the paracone of the upper carnassials or by the protoconid of the lower carnassials of a large carnivore with strong jaws and very pointed carnassials.
The paracone is on the anterior margin of the tooth and is larger than the metacone, which is on the posterior margin.
DISCUSSION The material represents a didelphid because the metacone is larger than the paracone, stylar cusps A, B, C and D are present, although variable, the stylar shelf is wide, and the centrocrista is V-shaped.
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.
