Summary[edit]

Description
English: Comparison of sample teeth from Mammut pacificus and Mammut americanum.
  • Mammut pacificus: (A–D) M3; (I–L) m3; (Q and R) M2; (U) m2; (W) M1; (Y) m1; (AA) dP4; (CC) dp4; (EE) dP3; (GG) dp3; (II) dP2; (KK) dp2
  • Mammut americanum: (E–H) M3; (M–P) m3; (S and T) M2; (V) m2; (X) M1; (Z) m1; (BB) dP4; (DD) dp4; (FF) dP3; (HH) dp3; (JJ) dP2; (LL) dp2

Remarks:

  • (A-H): Note the presence of a fifth loph in (C and D), and the weak to absent cingulum in all four M. pacificus specimens (contrast with the strong cingulum development in F).
  • (I-P): Note the absence or weak development of a cingulum in (I–L), and the variable morphology of the posterior to the fourth lophid, particularly in M. americanum
  • (Q and R): Note the weak cingulum development in (Q) and strong development in (R)
  • (EE-FF): Note the partial third loph in both taxa
  • (GG-HH): Note the partial third lophid in both taxa
Scale 10 cm

  • (I-P): Beachte die ausgebildete fünfte Leiste in (I–L) und die variable Morphologie hinter der vierten Leiste, vor allem bei M. americanum
  • (Q and R): Beachte das schwache Cingulum in (Q) und das deutliche in (R)
  • (EE-FF): Beachte die teilweise ausgebildete dritte Leiste in beiden Taxa
