The parapreconule is clearly visible at the anterior side of the paracone. The basal fossa is present at the base of the protocone.
The paracone bears a parastyle which is thick proximally but thin distally.
NAP XV 76'08, a well preserved left P4 shows an incipient wear facet on its lingual wall, affecting part of the paracone and the metastyle (Fig.
The paracone of Ml is connected with protocone by an enamel bridge situated at the posterior-most end of the protocone.
The paracone "lobule" is the largest because it likely involves the mesoloph plus the paralophule; a trace of the latter is present as an acute posterior edge.
UAP is described as the presence of a pronounced crest extending from the tip of the buccal cusp (paracone) towards the distal-occlusal ridge, almost reaching the sagittal sulcus.
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.
Rich.) 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.
The paracone and metacone are subequal in size with metacone positioned slightly toward the midline (linguad).
For all specimens, points were recorded at the midline, between the medial incisors ([ILLUSTRATION FOR FIGURE 1 OMITTED], point 1); at the cusp apices of the two upper incisors (at its distal end if the crown is spatulate; [ILLUSTRATION FOR FIGURE 1 OMITTED], points 2-3); at the apex of the [P.sup.4] paracone ([ILLUSTRATION FOR FIGURE 1A OMITTED], point 4; [ILLUSTRATION FOR FIGURE 1B OMITTED], C, point 5; for Stenodermatini and Glossophagini, an intermediate point was recorded at the apex of the [P.sup.3] paracone; [ILLUSTRATION FOR FIGURE 1B, C OMITTED], point 4); and at the apices of one or more labial cusps on two of the molars.
