The parapreconule is clearly visible at the anterior side of the paracone
. The basal fossa is present at the base of the protocone.
bears a parastyle which is thick proximally but thin distally.
Parastyle is usually observed on the mesiobuccal cusp (paracone
) and rarely on the distobuccal cusp (metacone) of the upper molars.
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.
of Ml is connected with protocone by an enamel bridge situated at the posterior-most end of the protocone.
"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.
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.
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.
